TomTom has also launched its new navigation engine, NavKit.

“Where navigation used to be about getting people to unfamiliar destinations, we are now empowering drivers with easy access to the information they need to make the smartest driving decisions, every day,” said Corinne Vigreux, managing director of TomTom Consumer. “We have completely redesigned the PND to become an essential daily driving tool. By providing easy access to our world class TomTom Traffic and enabling drivers to see more than just the road ahead, drivers will feel on top of their journey like never before.”

Drivers can easily access the travel information they need via a high-resolution, capacitive touchscreen, TomTom said. A new Interactive Map responds and scales to touch. Drivers can  zoom in and out to find and explore places on the map with their fingertips and tap on the map to get an instant route to a destination.

New NavKit Engine

TomTom’s navigation engine, NavKit, will power all future TomTom navigation products and be available for licensing to automotive and enterprise customers. The configurable component architecture has been designed to enable rapid integration. NavKit has programming interfaces for adding a customised user interface, porting to any operating system and integrating navigation services. As a result, the development of a connected navigation system on any device platform becomes far quicker and simpler, TomTom said.

The new NavKit engine incorporates all the navigation logic of an on-board turn-by-turn navigation application. Every element has been enhanced to deliver an improved user experience including route planning, free text search, 2D map browsing and 3D guidance view, map-matched positioning and real-time guidance, TomTom said.

“The automotive industry’s next challenge is to create a seamless connected car experience,” said Harold Goddijn, CEO at TomTom. “To help our customers achieve this, we created NavKit, a flexible, future-proof navigation platform. NavKit makes the creation of connected navigation solutions easier and faster than ever before.”

NavKit’s architecture will allow customers and industry partners to replace components in a modular way. Its new routing engine achieves faster and more accurate dynamic routing, both on TomTom’s maps and on Navigation Data Standard (NDS) maps. Additionally, it provides better routes around traffic and fully supports TomTom Traffic, Version 6.0, including incident duration predictions and jam tail warnings. The new free text search engine provides easier and faster address and POI search. A new map visualization engine greatly improves 2D map browsing and introduces a 3D guidance view.

TomTom GO Features

The new TomTom GO series also comes with Lifetime TomTom Traffic. TomTom’s world-class traffic information pinpoints exactly where delays start and end, helping drivers to get to their destinations faster. Drivers can choose to connect to TomTom Traffic in one of two ways, either via Smartphone Connected or Always Connected. Smartphone Connected devices are ready to receive TomTom Traffic by connecting to a smartphone via Bluetooth. Smartphone Connected uses an existing smartphone data plan to access TomTom Traffic, as well as other services like TomTom Speed Cameras.

Always Connected devices offer the simplest way to receive TomTom Traffic straight out of the box, TomTom said. With connectivity built-in and with no additional costs for roaming, drivers can access TomTom Traffic and other services, including TomTom Speed Cameras.

3D Maps bring buildings and landmarks to life so that drivers always know exactly where they are.

The new TomTom GO range has a simplified product line-up. Customers can select their preferred screen size, choosing from a 4.3″, 5″ or 6″ model; then decide how they prefer to receive their TomTom Traffic information, either via Smartphone Connected or Always Connected.

Additional TomTom GO Features

Route Bar: Essential traffic and travel information at a glance. The Route Bar shows precise traffic and speed camera information on the road ahead.

Quick Search: Drivers can find their destination faster with intuitive search results. Quick Search starts finding destinations as soon as the driver starts typing.

My Places: Drivers can see their favourite locations on the map and personalise their map with My Places. This makes it easier to find and navigate to favourite locations again and again.

Lifetime Maps: Always drive with the latest map. For the life of the product, drivers can download four or more full updates of the map onto the device, every year. Drivers receive all updates to the road network, addresses and Points of Interest.

Speed Cameras (three month trial): Drivers can drive in a more relaxed way, receiving alerts for speed cameras ahead. These timely warnings increase drivers’ awareness of local speed limits and help to save money on speeding fines. As part of TomTom’s global driving community, drivers will benefit from an advanced and highly accurate warning service.

Emerging GNSS applications in automobiles support regulation, security, safety, and financial transactions, as well as navigation, guidance, traffic information, and entertainment. The GNSS sub-systems and onboard applications must demonstrate robustness under a range of environments and varying threats. A dedicated automotive GNSS test center enables engineers to design their own GNSS test scenarios including urban canyons, tunnels, and jamming sources at a controlled test site.

By Mark Dumville, William Roberts, Dave Lowe, Ben Wales, NSL, Phil Pettitt, Steven Warner, and Catherine Ferris, innovITS

Satellite navigation is a core component within most intelligent transport systems (ITS) applications. However, the performance of GNSS-based systems deteriorates when the direct signals from the satellites are blocked, reflected, and when they are subjected to interference. As a result, the ability to simulate signal blockage via urban canyons and tunnels, and signal interference via jamming and spoofing, has grown fundamental in testing applications.

The UK Center of Excellence for ITS (innovITS), in association with MIRA, Transport Research Laboratory (TRL), and Advantage West Midlands, has constructed Advance, a futuristic automotive research and development, and test and approvals center. It provides a safe, comprehensive, and fully controllable purpose-built road environment, which enables clients to test, validate and demonstrate ITS. The extensive track layout, configurable to represent virtually any urban environment, enables the precise specification of road conditions and access to infrastructure for the development of ITS innovations without the usual constraints of excessive set up costs and development time.

As such, innovITS Advance has the requirement to provide cityscape GNSS reception conditions to its clients; a decidedly nontrivial requirement as the test track has been built in an open sky, green-field environment (Figure 1).

Figure 1. innovITS Advance test circuit (right) and the environment it represents (left).

NSL, a GNSS applications and development company, was commissioned by innovITS to develop Skyclone in response to this need. The Skyclone tool is located between the raw GNSS signals and the in-vehicle system. As the vehicle travels around the Advance track, Skyclone modifies the GNSS signals to simulate their reception characteristics had they been received in a city environment and/or under a jamming attack. Skyclone combines the best parts of real signals, simulated scenarios, and record-and-replay capabilities, all in one box. It provides an advanced GNSS signal-processing tool for automotive testing, and has been specifically developed to be operated and understood by automotive testing engineers rather than GNSS experts.

Skyclone Concept

Simulating and recreating the signal-reception environment is achieved through a mix of software and hardware approaches. Figure 2 illustrates the basic Skyclone concept, in which the following operations are performed.

• In the office, the automotive engineer designs a test scenario representative of a real-world test route, using a 3D modelling tool to select building types, and add tunnels/underpasses, and jammer sources. The test scenario is saved onto an SD card for upload onto the Skyclone system.
• The 3D model in Skyclone contains all of the required information to condition the received GNSS signals to appear to have been received in the 3D environment.
• The Skyclone system is installed in a test vehicle that receives the open-air GNSS signals while it is driven around the Advance track circuit.
• The open-air GNSS signals are also received at a mobile GNSS reference receiver, based on commercial off-the-shelf GNSS technology, on the test vehicle. It determines the accurate location of the vehicle using RTK GNSS. The RTK base station is located on the test site.
• The vehicle’s location is used to access the 3D model to extract the local reception conditions (surrounding building obstructions, tunnels attenuations, jamming, and interference sources) associated with the test scenario.
• Skyclone applies satellite masking, attenuation, and interference models to condition/manipulate raw GNSS signals received at a second software receiver in the onboard system. The software receiver removes any signals that would have been obstructed by buildings and other structures, and adds attenuation and delays to the remaining signals to represent real-world reception conditions. Furthermore, the receiver can apply variable interference and/or jamming signatures to the GNSS signals.
• The conditioned signals are then transmitted to the onbaord unit (OBU) under test either via direct antenna cable, or through the air under an antenna hood (acting as an anechoic chamber on top of the test vehicle). Finally, the GNSS signals produced by Skyclone are processed by the OBU, producing a position fix to be fed into the application software.

Figure 2. Skyclone system concept.

The Skyclone output is a commercial OBU application that has been tested using only those GNSS signals that the OBU receiver would have had available if it was operating in a real-world replica environment to that which was simulated within the Skyclone test scenario.

Skyclone Architecture

The Skyclone system architecture (Figure 3) consists of five principal subsystems.

Office Subsystem Denial Scenario Manager. This software has been designed to allow users to readily design a cityscape for use within the Skyclone system. The software allows the users to select different building heights and styles, add GNSS jamming and interference, and select different road areas to be treated as tunnels.

Figure 3. Baseline Skyclone system architecture.

City Buildings. The Advance test site and surrounding area have been divided into 14 separate zones, each of which can be assigned a different city model. Ten of the zones fall inside of the test road circuit and four are external to the test site. Each zone is color-coded for ease of identification (Figure 4).

Figure 4. Skyclone city zones.

The Skyclone system uses the city models to determine GNSS signal blockage and multipath for all positions on the innovITS Advance test site. The following city models, ordered in decreasing building height and density, can be assigned to all zones: high rise, city, semi urban, residential, and parkland.

Interference and Jamming. GNSS jamming and interference can be applied to the received GNSS signals. Jamming is set by specifying a jamming origin, power, and radius. The power is described by the percentage of denied GNSS signal at the jamming origin and can be set in increments of 20 percent. The denied signal then decreases linearly to the jammer perimeter, outside of which there is no denial.

The user can select the location, radius, and strength of the jammer, can select multiple jammers, and can drag and drop the jammers around the site.

Tunnels. Tunnels can be applied to the cityscape to completely deny GNSS signals on sections of road. The user is able to allocate “tunnels” to a pre-defined series of roads within the test site. The effect of a tunnel is to completely mask the sky from all satellites.

Visualization. The visualization display interface (Figure 5) provides a graphical representation of the scenario under development, including track layout, buildings, locations, and effects of interference/jammers and tunnels. Interface/jammer locations are shown as hemispherical objects located and sized according to user definition. Tunnels appear as half-cylinder pipes covering selected roads.

Figure 5. 3D visualisation display.

Reference Subsystem

The reference subsystem obtains the precise location of the test vehicle within the test site. The reference location is used to extract relevant vehicle-location data, which is used to condition the GNSS signals.

The reference subsystem is based on a commercial off-the-shelf real-time kinematic GPS RTK system, capable of computing an accurate trajectory of the vehicle to approximately 10 centimeters. This position fix is used to compute the local environmental parameters that need to be applied to the raw GNSS signals to simulate the city scenario.

A dedicated RTK GNSS static reference system (and UHF communications links) is provided within the Skyclone system. RTK vehicle positions of the vehicles are also communicated to the 4G mesh network on the Advance test site for tracking operational progress from the control center.

Vehicle Subsystem

The vehicle subsystem acquires the GNSS signals, removes those that would be blocked due to the city environment (buildings/tunnels), conditions remaining signals, applies interference/jammer models, and re-transmits resulting the GNSS signals for use by the OBU subsystem.

The solution is based on the use of software GNSS receiver technology developed at NSL. In simple terms, the process involves capturing and digitizing the raw GNSS signals with a hardware RF front end. Figure 6 shows the system architecture, and Figure 7 shows the equipment in the innovITS demonstration vehicle.

Figure 6. Skyclone hardware architecture.

Figure 7. Equipment in the innovITS demonstration vehicle.

The digitized signals are then processed in NSL’s software receiver running on a standard commercial PC motherboard. The software receiver includes routines for signal acquisition and tracking, data demodulation and position determination.

In the Skyclone system, the raw GNSS signals are captured and digitized using the NSL stereo software receiver. The software receiver determines which signals are to be removed (denied), which signals require conditioning, and which signals can pass through unaffected. The subsystem does this through accurate knowledge of the vehicle’s location (from the reference subsystem), knowledge of the environment (from the office subsystem), and knowledge of the satellite locations (from the vehicle subsystem itself).

The Skyclone vehicle subsystem applies various filters and produces a digital output stream. This stream is converted to analog and upconverted to GNSS L1 frequency, and is sent to the transmitter module located on the same board.

The Skyclone transmitter module feeds the analog RF signal to the OBU subsystem within the confines of a shielded GPS hood, which is attached to the vehicle on a roof rack.  An alternative to the hood is to integrate directly with the cable of the OBU antenna or through the use of an external antenna port into the OBU.  The vehicle subsystem performs these tasks in near real-time allowing the OBU to continue to incorporate non-GNSS navigation sensors if applicable.

Onboard Unit Subsystem

The OBU subsystem, typically a third-party device to be tested, could be a nomadic device or an OEM fitted device, or a smartphone. It typically includes a GNSS receiver, an interface, and a software application. Examples include:

• Navigation system
• Intelligent speed adaptation system
• eCall
• Stolen-vehicle recovery system
• Telematics (fleet management) unit
• Road-user charging onboard unit
• Pay-as-you-drive black-box
• Vehicle-control applications
• Cooperative active safety applications
• Vehicle-to-vehicle and vehicle-to-infrastructure systems.

Tools Subsystem Signal Monitor

The Skyclone Monitor tool provides a continuous monitoring service of GNSS performance at the test site during tests, monitoring the L1 frequency and analyzing the RF singal received at the reference antenna. The tool generates a performance report to provide evidence of the open-sky GNSS conditions. This is necessary in the event of poor GNSS performance that may affect the outcome of the automotive tests. The Skyclone Monitor (Figure 8) is also used to detect any spurious leaked signals which will highlight the need to check the vehicle subsystem. If any spurious signals are detected, the Skyclone system is shut down so as to avoid an impact on other GNSS users at the test site. A visualization tool (Visor) is used for post-test analysis displaying the OBU-determined position alongside the RTK position within the 3D environment.

Figure 8. GNSS signal and positioning monitor.

Performance

Commissioning of the Skyclone system produced the following initial results. A test vehicle was installed with the Skyclone and RTK equipment and associated antennas.. The antennas were linked to the Skyclone system which was installed in the vehicle and powered from a 12V invertor connected to the car power supply. The output from the RTK GPS reference system was logged alongside the output of a commercial third-party GNSS receiver (acting as the OBU) interfaced to the Skyclone system. Skyclone was tested under three scenarios to provide an initial indication of behavior: city, tunnel, and jammer.

The three test cenarios were generated using the GNSS Denial Scenario Manager tool and the resulting models stored on three SD cards. The SD cards were separately installed in the Skyclone system within the vehicle before driving around the test site.

City Test. The city scenario consisted of setting all of the internal zones to “city” and setting the external zones to “high-rise.”

Figure 10A represents the points as provided by the RTK GPS reference system installed on the test vehicle. Figure 10B includes the positions generated by the COTS GPS OBU receiver after being injected with the Skyclone output. The effect of including the city scenario model is immediately apparent. The effects of the satellite masking and multipath model generate noise within the position tracks.

Figure 10A. City scenario: no Skyclone.

Figure 10B. City scenario: withSkyclone.

Tunnel Test. The tunnel scenario consists of setting all zones to open sky. A tunnel is then inserted along the central carriageway (Figure 11). A viewer location (depicted by the red line) has been located inside the tunnel, hence the satellite masking plot in the bottom right of Figure 11 is pure red, indicating complete masking of satellite coverage. The output of the tunnel scenario is presented in Figure 12. Inclusion of the tunnel model has resulted in the removal of all satellite signals in the area of track where the tunnel was located in the city model. The color shading represents signal-to-noise ratio (SNR), an indication of those instances where the output of the test OBU receiver has generated a position fix with zero (black) signal strength, hence the output was a prediction. Thus confirming the tunnel scenario is working correctly.

Figure 11. 3D model of tunnel.

Figure 12. Results.

Jammer Test. The jammer test considered the placement of a single jammer at a road intersection (Figure 13). Two tests were performed, covering low-power jammer and a high-power jammer. Figure 14A shows results from the low-power jammer. The color shading relates to the SNR as received within the NMEA output from the OBU, which continued to provide an output regardless of the jammer. However, the shading indicates that the jammer had an impact on signal reception.

Figure 13. Jammer scenario.

Figure 14A. Jammer test results: low power interference.

Figure 14B. Jammer test results: high-power interference.

In contrast the results of the high-power jammer (Figure 14B) show the effect of a jammer on the OBU output. The jammer denies access to GNSS signals and generates the desired result in denying GNSS signals to the OBU. Furthermore, the results exhibit features that the team witnessed during real GNSS jamming trials, most notably the wavering patterns that are output from GNSS receivers after they have regained tracking following jamming, before their internal filtering stabilizes to nominal behaviors.

The Future

The Advance test site is now available for commercial testing of GNSS based applications. Current activity involves integrating real-world GNSS jammer signatures into the Skyclone design tool and the inclusion of other GNSS threats and vulnerabilities.

Skyclone offers the potential to operate with a range of platforms other than automotive. Unmanned aerial systems platforms are under investigation. NSL is examining the integration of Skyclone features within both GNSS simulators as well as an add-on to record-and-replay tools. This would enable trajectories to be captured in open-sky conditions and then replayed within urban environments.

Having access to GNSS signal-denial capability has an immediate commercial interest within the automotive sector for testing applications without the need to invest in extensive field trials. Other domains can now benefit from such developments. The technology has been developed and validated and is available for other applications and user communities.

The number of cyclists in London is on the rise, along with safety risks that arise when trucks and cyclists both are traversing busy London junctions and interchanges.

The ProNav HGV Cyclist Alert software was developed in association with Transport for London (TfL) to provide a commercial vehicle driver with an audible and visual alert as he or she approaches a junction (or section of road) that has been determined to be a location where there are  high volumes of HGVs and cyclists. A warning symbol is displayed on the navigation system’s mapping that projects a 50-meter radius “warning zone” around each HGV/Cyclist convergence area. Drivers are also provided with a short audible tone as a reminder, giving the driver plenty of time to check for any cyclists on the road, Navevo said.

The HGV Cyclist Alert software uses data provided by TfL and the up-to-date Department for Transport HGV and pedal cycle flow figures for London’s road network. The dataset uses this information to identify locations where large numbers of HGVs and cyclists converge. Initially, 100 high-convergence areas across London have been included (alerts at every junction would be counterproductive to drivers). Working with other local authorities both in London and nationally, Navevo plans to increase the level of coverage and will provide free updates when new data becomes available.

“A navigation system is something a driver is likely to be listening to as they approach a junction, and so it makes perfect sense to also alert the driver of the risk of cyclists, reminding them to be observant and drive safely,” says Navevo CEO, Nick Caesari. “The safety of drivers, cyclists and other users of the road is a concern for everybody, and we are proud to lead the navigation industry by launching this ‘world first’ safety feature, which we believe could significantly contribute in improving road safety and reducing the number of incidents involving HGVs and cyclists.”

“For many years, London has worked to lead the way in pushing for the adoption of safer lorries and safer lorry driving,”
Ian Wainwright, head of Freight and Fleet at Transport for London. “The creation of a specific cyclist alert for HGV drivers is another positive step forward and will help to further raise awareness and improve cycle safety across the capital.”

A LocataNet will provide the vitally important high-precision positioning required by the VRC to perform rigorous, consistent and repeatable scientific evaluation of the new vehicle crash avoidance systems, Locata said. VRC crash tests produce the “Top Safety Pick” ratings that have helped consumers make informed decisions about buying safer cars for years. Now research into new technology systems, which allows cars to avoid crashes in the first place, will elevate the value of the institute’s safety ratings, Locata said.

Carrying out these new tests is not a trivial exercise, Locata said. The VRC will have to research and install new robotic and positioning technology to enable the required level of precision. The LocataNet installation will furnish the IIHS with a locally controlled positioning system that is seamless over all of the VRC test areas, enabling extremely reliable automated positioning of vehicles. The newly expanded facility includes a continuous vehicle test track that traverses not only open-air roadway areas, but also a vast 300- by 700-foot fully covered testing area. Locata’s ability to provide centimeter-accurate, locally controlled positioning across both outdoor and indoor environments gives the IIHS flexibility to design a positioning system to meet their vital test requirements, while also allowing easy upgrade and expansion in the future, Locata said.

The IIHS will use Locata positioning to control automated testing of frontal collision avoidance and other safety systems.

The dramatic video footage from IIHS crash tests draws extensive media coverage, which becomes a powerful public incentive for automakers to improve the safety of their vehicles. The media, auto industry and policymakers look to the IIHS as a leader in highway safety research, and the expanded VRC will enable the IIHS to play a major role in the emerging area of crash avoidance testing, Locata said. IHS’s YouTube channel shows crash tests and dicusses the ratings system.

“Crash tests and research conducted at the VRC have helped drive life-saving improvements in vehicle designs,” said Adrian Lund, IIHS president. “Our new state-of-the-art facility will allow us to also evaluate emerging vehicle-based systems intended to prevent crashes or lessen their severity, so that we can encourage the entire industry to adopt the most effective ones.”

To do this new research, it is essential to conduct tests under identical, controlled condition, Locata said. With Locata, IIHS researchers will be able to ensure precise positioning data is available in all of its test areas. In places where GPS signals would be unreliable or unavailable when tests are conducted under cover, Locata seamlessly delivers consistent, reliable and accurate positioning, available everywhere, the company said. It will help IIHS carry out automated, identical testing to allow “apples to apples” comparisons of motor vehicles. This is a critical advancement for testing systems that will save many lives in the future, Locata said.

Here is a video tour of the VRC.

Locata technology provides GPS-style, ground-based positioning covering local areas ranging in size from a parking lot to thousands of square miles. It provides precise positioning either in combination with, or in the total absence of, GPS. It is the first technology that can replicate GPS’s precise positioning capability without using satellites.

Locata’s current devices have already delivered new positioning capabilities to professional applications in mining, aviation, warehousing, and as “GPS backup systems” for important strategic areas. Locata is being trialed by several government bodies in urban areas as a locally controlled positioning infrastructure in applications for transport, first responders, surveyors, and container port automation. As Locata devices are further miniaturized over the next few years, this technology promises to be a game changer for the positioning capabilities available to indoor, mobile and smartphone applications, Locata said.

The partners met at the VRC on February 14 to plan out the Locata installation. From left are Robert “Bo” Jones, IIHS engineer; Paul Perrone, president, Perrone Robotics; Geoff Hoekstra, business development, Perrone Robotics; Adrian Lund, president, IIHS; David Zuby, chief research officer, IIHS; Nunzio Gambale, Locata CEO; Jimmy LaMance, Locata. The auto is the result of a crash test conducted that day.

“GPS satellites are in a constant state of motion,” said Nunzio Gambale, CEO of Locata Corporation. “In many environments, this makes it impossible to achieve the level of reliable positioning required for meaningful scientific testing. Locata readily steps into these environments to deliver an always-on, unfailing and superbly accurate positioning signal. We are honored to be chosen as the positioning technology that helps the IHS research, test and drive forward the development of life-saving automotive initiatives. This Locata installation at the legendary Vehicle Research Center will be the most publicly visible jewel in our crown to date. Relationships like this confirm the value of years of hard work we put in to invent this amazing and unique technology.”

“The Locata team is thrilled to see how rapidly our systems are being taken up by the creme-de-la-creme of the positioning industry,” continued Gambale. “We know this VRC testing is world-first, groundbreaking work that has enormous global and social value. It’s wonderful to think that our work may contribute to one day saving my life—or yours.”

But a judge of the appellate court said holding a phone to look at a map is distracted driving — the same as sending a text message — and the law applies.  “Our review of the statute’s plain language leads us to conclude that the primary evil sought to be avoided is the distraction the driver faces when using his or her hands to operate the phone. That distraction would be present whether the wireless telephone was being used as a telephone, a GPS navigator, a clock or a device for sending and receiving text messages and emails. This case requires us to determine whether using a wireless phone solely for its map application function while driving violates Vehicle Code section 23123. We hold that it does. “

The National Safety Council has noted that there is no research or evidence that indicates voice-activated technologies eliminate or even reduce the distraction to the drivers’ mind.

The Furuno eRideOPUS 7.

Furuno Electric Co., Ltd., has announced that new multi-GNSS receiver chips eRideOPUS 6 and eRideOPUS 7 will be available in August. The new receiver chips are multi-GNSS compliant single-chip LSIs, capable of concurrently receiving signals from multiple satellites in GNSS systems and satellite-based augmentation systems, as well as Japan’s Quasi-Zenith Satellite System. Both chips receive signals from GPS and Galileo; the eRideOPUS 7 also receives GLONASS signals.

The ability of concurrently receiving GNSS/GNSS augmentation signals from multiple satellites from different satellite services means that the receivers have more probability of acquiring a greater number of satellites at any single time. Subsequently, position stability as well as accuracy will be greatly improved, minimizing the chance of a position lost. Also, the receiver chips incorporate an enhanced level of noise rejection capability, implementing the anti-jamming function as well as the improvement of multipath mitigation.

Time-to-first-fix capability of the existing eRideOPUS 5 (no more than 1 second when hot started) is retained in these new receiver chips with a combination of A-GPS compatibility and self-ephemeris extraction. Moreover, the position update rate of the new receiver chips is greatly improved, achieving a 10-Hz update (every 0.1 second), which is twice as fast as the capability achieved by eRideOPUS 5.

The new receiver chips are capable of dead-reckoning navigation, using a gyro sensor and vehicle speed pulse signals, a gyro sensor and an acceleration sensor, and wheel tick data taken from a CAN-Bus network, achieving high positioning accuracy even in locations where satellite signal reception is not available, such as inside tunnels.

In May 2013, Furuno is planning to start the delivery of evaluation kits for the receiver chips so that third-party manufacturers can evaluate the feasibility of incorporating the receiver chips into their products, and in August 2013, the new compact GNSS receiver module GN-86/GN-87 as well as
dead-reckoning-capable GV-86/GV-87, using these new receiver chips, will be made available for automotive navigation systems as well as eCall systems.

Following the recent announcement of Magellan’s SmartGPS device, the free Magellan SmartGPS Apps for iOS and Android devices are the next key elements in Magellan’s Smart Ecosystem, a cloud platform that integrates social media and navigation content directly onto a navigation map, the company said. The SmartGPS Apps automatically deliver continually updating reviews and tips for local businesses from social media including Yelp, Foursquare, and other partners to create current, local and personalized driving and pedestrian experiences.

The Magellan SmartGPS mobile apps display location-relevant information “squares” that graphically flip to show reviews, tips and offers from Yelp and Foursquare for nearby restaurants, stores and services. Users can then navigate to those locations directly from the SmartGPS App without needing to open an additional application or device. The cloud architecture enables new monetization of end users’ mobile search and navigation, and additional social media and content partners.

“We architected the Smart Ecosystem to integrate with automotive infotainment and mobile network service platforms so users can enjoy a truly mobile, connected car experience now,” said Peggy Fong, president of MiTAC Digital Corporation. “SmartGPS mobile apps connect to the vehicle dash, allowing users to easily search social media and points-of-interest for destinations, and send the locations via Bluetooth or Wi-Fi to SmartGPS-enabled vehicle navigation systems.”

Magellan’s free iOS and Android SmartGPS apps create a total-solution SmartGPS experience that is truly mobile. Magellan connects the smartphone to the vehicle dashboard, enabling location sync and sharing, hands-free operation and data connectivity. Users can pair their Magellan SmartGPS app with SmartGPS-enabled navigation systems. Using their SmartGPS App, SmartGPS enabled navigation system, or PC, users can search for a location, save the location in Magellan’s Smart Ecosystem cloud, and sync and share the location to any SmartGPS enabled device via Wi-Fi or Bluetooth.

The free Magellan SmartGPS Apps will be available in North America this Spring, and in Europe this Summer, from iTunes and Google Play. Premium versions of both apps featuring spoken turn-by-turn navigation will also be available.

Broadcom will showcase its GNSS innovations at the upcoming Mobile World Congress show in Barcelona, February 25-28.

A geographical region of interest (“geofence”) is being used by many new and innovative location-aware applications. The geofence feature enables the application to receive a notification when a user enters or exits a virtual perimeter. However, the implementation of this feature in traditional architectures is not viable, as the applications processor needs to run constantly, causing rapid drain to the device’s battery. Broadcom’s new BCM47521 overcomes this issue, making it possible to continuously monitor geofence areas while consuming 60x less battery power.

“The astounding growth of mobile devices is driving new opportunities for inventive applications that deliver valuable location-aware information,” said Scott Pomerantz, Broadcom vice president and general manager, GPS. “With the BCM47521’s low-power geofence mode, Broadcom is driving the next wave of system power consumption innovation that will allow OEMs to incorporate features that differentiate their mobile offerings and make location-aware, always-on applications a reality.”

The BCM47521 chip also provides multi-constellation support by simultaneously collecting data from GPS, GLONASS, QZSS and SBAS, and using the best received signals, resulting in faster searches and more accurate real-time navigation, Broadcom said. Broadcom’s multi-constellation technology, coupled with advanced signal processing, provides faster positioning performance for improved user experience, especially in challenging urban environments where buildings and obstructions can dramatically impact accuracy and time-to-first-fix.

A key feature is the 60x better system power efficiency versus a host-based architecture. An advanced host-offload mode monitors geofences in the background and only activates the applications processor when there is a trigger event, and smart algorithms adapt in real-time as the user gets closer to a geofence boundary.
