In 2011 the European GNSS Agency (GSA) awarded GMV the EEGS2 project (EGNOS Extension to Eastern Europe). The main objective of the project is to demonstrate through flight trials the benefits of the European Geostationary Navigation Overlay Service (EGNOS) in areas of Eastern Europe where it is not yet available, such as Poland, Romania, Ukraine, Moldova and Russia, and to prepare the civil aviation authorities and air navigation service providers for future use of the system.

GMV’s magicSBAS solution.

In the context of this project, after the tests conducted in Spain, the maiden flights have been successfully carried out in Moldova, using the equipment and tools developed by GMV. The Moldova demonstrations have given pilots and service providers a clear idea of the potential benefits of EGNOS and the flying procedures of the near future, GMV said.

Four flights had previously been conducted in Spain in November, December and February. The satisfactory results of these flights then paved the way for the demonstrations in Moldova.

The magicLPV system, developed under this project, enables LPV approaches (localizer performance with vertical guidance) to be carried out using the signal generated by the magicSBAS application. This test environment allows any region of the world to analyze the air-navigation benefits to be obtained with deployment of a Space Based Augmentation System (SBAS). This signal is read by Internet and transmitted by radio frequency in the vicinity of the airport, allowing LPV approaches to be made in places where SBAS is either completely unavailable or available only on a very limited basis.

Eight flights in all were carried out in various Moldovan airports, including Chișinău International Airport. Test results were highly satisfactory, demonstrating the simplicity of equipment configuration and operation, and the performance of the magicSBAS signal, GMV said.

“These trials are an important milestone for GMV, for the project and, fundamentally, for the use of EGNOS in the countries of Eastern Europe in the near future,” said Miguel Romay, executive director of GNSS–Aerospace.

GMV will continue with these demonstrations in other countries of Eastern Europe. The next trip in two weeks will be to Romania, where new flights are expected to be just as successful.

The spectrum of today’s providers seems to range from highly sophisticated scientific systems used for development by precision receiver manufacturers, through systems with GNSS and aiding solutions, to specialized systems for both general and specific application developers and also for production test. So this month I’d like to try to summarize (in no particular order) what some of the suppliers of GNSS simulation systems are up to, how they may be positioned in the market and, wherever possible, what we might expect to see from them in the future.

GSG Series 6 GNSS simulator.

Spectracom is a more recent entrant to the GNSS simulation market, though the company has been providing frequency and time synchronization test equipment for about 40 years. Spectracom has integrated GPS into these products for more than ten years, and decided three years ago to use the knowledge it had gained to get into the GNSS simulation business.

The GSG family of simulators is positioned at the “affordable” end of the simulation equipment scale, and is targeted at users and integrators of GNSS, rather than developers of receivers. Spectracom claims to have about 80 percent of the features of the top-end simulations systems, but its more capable (Series 6) systems sell in the $20-30k range. While new to the business, the Spectracom team feels that this allows them to bring the newest technology and innovation to the market.

The Spectracom system is derived from its well-known frequency/time synthesizer equipment — in fact, it has the same look front panel and chassis — and also makes use of the same “easy-to-use” concepts. “It doesn’t take a navigation scientist to operate these simulators,” said John Fischer, chief technology officer at Spectracom. The accompanying Studio View software is reportedly relatively easy to use to generate trajectories and other test scenarios by connecting to Google Maps and uploading them to the simulator.

But with all new firmware and FPGA implementation, 64 channels, and four frequency bands covering both GPS and GLONASS, the GSG family appears to be very well positioned for application developers integrating GNSS. Galileo and Beidou/Compass are in the works and expected this year, and will be supplied as upgrades to existing equipment.

Spectracom anticipates significant growth in its target market for application developers in “anything that moves,” including automotive and airborne, video matching, radar/lidar, and handheld nav devices, including mobile phones. Spectracom has a number of product lines and around 100 people working for them, but the GNSS simulation group is around 12 strong.

Rohde & Schwarz is another relatively recent GNSS simulation entrant with new products for the market.

SMBV100A vector signal generator.

Its current offering — the SMBV100A Vector Signal Generator – can simulate 24 dynamic GPS, GLONASS and Galileo satellites.  The SMBV 100A has wide bandwidth and high output power levels. Real-time test scenarios can be customized by the user — including a neat facility that allows modeling of satellite masking by downtown buildings, along with anticipated multipath for the same urban scenario.

While somewhat new to GNSS simulation, R&S has been around since the 1930s, and its experience with frequency synthesizers and similar equipment is being carried forward into what the company terms its “cost-effective” GNSS simulation offerings. R&S anticipates significant growth in automotive, aerospace, UAV, and cellular assisted-GNSS application markets.

R&S has had success in the aerospace market for UAVs, and has developed the capability to model antenna patterns and UAV body mask as the vehicle rotates and attitude changes towards visible satellites. Along the same lines, R&S has hooked up its system to flight simulators and provided hardware-in-the-loop testing for clients. R&S also has the ability to run simulation scenarios for long periods of time, and for “very long” periods if the receiver is stationary — this feature makes use of large internal memory storage within the SMBV100A; of course, almanac validity limits just how long this is possible. P-code capability is provided as an option, and there is a roadmap for adding SBAS and Beidou capability later.

IFEN NavX-NCS Professional

In the meantime, IFEN in Germany is focusing on its NavX-NCS Navigation Constellation Simulator range of multi-GNSS signal simulators.

IFEN emphasizes the flexibility of its design, with a platform scalable from a 12-channel GPS L1 system up to a full multi-GNSS system with 108 channels and 9 frequencies for GPS, GLONASS, Galileo, QZSS and SBAS. With this building-block approach, channels and capabilities can be added as and when additional testing complexity is required.

IFEN claims that the capability to generate all GNSS signals — by combining different modulations with up to nine L-band frequencies — is the only existing solution on the market providing GPS, Galileo, GLONASS, QZSS and SBAS in one chassis at the same time. And, since April 2013, all IFEN NavX-NCS GNSS RF signal simulators are to include BeiDou B1 signal capability in accordance with the official Chinese BeiDou B1 ICD, and are ready for the other B2 and B3 BeiDou signals.

IFEN also founded a subsidiary in the USA in January this year called IFEN, Inc., located in California and operational with Mark Wilson (formerly with Spirent) as VP Sales. In addition, IFEN has formed a partnership with WORK Microwave — a leading European manufacturer of advanced satellite communications and navigation equipment. WORK Microwave is responsible for RF and digital hardware design while IFEN develops the associated software and manages the distribution of the product range.

Little-known IP-Solutions in Tokyo, Japan, has been working to develop its ReGen GNSS DIF signal simulator, a software simulator that simulates ionospheric effects, generates digital IF (DIF) signals similar to those recorded by an RF recorder, and comes with an optional capability of simulating integrated inertial navigation.

IP-Solutions’ digital IF baseband signal simulator ReGen has been developed in close cooperation with the Japan Aerospace Exploration Agency (JAXA) to test and validate GNSS signal processing algorithms and methods for use on board aircraft using tight and ultra-tight integration with INS, including specific scintillation models and ionospheric bubble simulation.

Various configurations of ReGen can produce multichannel GPS and GLONASS L1 signals and single-channel GPS L1, L2, L5 and GLONASS L1 and L2 signals, as well as simulating noise and interference.

Meanwhile, Spirent, arguably the original market leader in GNSS simulation, has continued along its chosen path of supplying the industry with the greatest capability and most extensive simulation systems.

Spirent has recently released test systems with support for China’s BeiDou Navigation Satellite System in addition to GPS, GLONASS and Galileo.

Spirent started shipping BeiDou-ready systems to its customers in 2012. Now these may be upgraded to full BeiDou capability using the information available in the first full issue of the BeiDou-2 Signal In Space Interface Control Document (ICD).

Also aiming at mobile applications, Spirent’s Hybrid Location Technology Solution (HLTS) integrates Wi-Fi, Assisted Global Navigation Satellite System (A-GNSS), Micro Electro-Mechanical Systems (MEMS) sensor and cellular positioning technologies. HLTS integrates four very different and distinct location technologies and provides repeatable and reliable lab-based characterization of mobile devices supporting hybrid location technologies that will enable “accurate everywhere” location — including indoor user location determination.

Other notable players in the GNSS simulation business include Racelogic, CAST Navigation and Agilent who are each pursuing their chosen niches in this expanding market segment. Racelogic’s LabSat GPS simulator is gaining popularity with a number of leading companies, providing the ability to record and replay real GNSS RF data as well as user-generated scenarios. CAST has an extensive line-up of GPS and GPS/INS simulation systems and support software, and Agilent has added to its impressive electronic testing portfolio with a very capable looking GPS simulation product line.

Several other companies — some based in China and Russia — are also trying to figure out their development and marketing strategies to conquer their chosen GNSS simulation market niche. This is all a very healthy sign that there are many other companies with new embedded GNSS applications that they are bringing to market and who therefore need GNSS simulation/test capability. Overall, this means there is still significant growth underway and far wider applications of GNSS on their way to market. Great news for the GNSS industry!

“We know that most GPS watches on the market are too bulky and complicated to use while training,” said Corinne Vigreux, managing director, TomTom Consumer. “Just as we developed easy-to-use navigation products that changed the way that people move from A to B, we have developed a range of ultra-slim GPS sport watches that are far more comfortable to wear and far easier to use. Runners and multi-sport athletes can now view their performance information at-a-glance, making it easier to achieve their fitness goals.”

The new TomTom watches feature an extra-large, high-resolution and high-contrast display that makes it easy for runners and multi-sport enthusiasts to quickly see their distance, time and pace while they workout even in bright sunshine, TomTom said.

The new watches feature TomTom’s Graphical Training Partner. Easy-to-read full-screen graphics help users get the most out of their workouts. They can view their real-time performance at-a-glance with three graphical training modes:

Race: Race against a personal best or most recent run. Quickly track performance with real-time graphics, to continue to improve run-after-run.
Goal: Set a distance, time or calorie goal and see progress toward that goal with simple, full-screen graphics and alerts.
Zone: Set a target for pace or heart-rate (with optional heart-rate monitor) and track progress in a simple full-screen graph throughout a workout.

The new TomTom range includes an intuitive one-button control that enables users to easily navigate up-down-left-right through menus to access key stats and watch features, the company said. Unlike the majority of existing GPS watches on the market that feature multiple small and hard-to-operate buttons, the one-button control is easy to operate while moving and can be easily controlled in all weather conditions and while wearing gloves.

In addition to their ability to deliver at-a-glance performance information, the TomTom Runner and TomTom Multi-Sport include advanced features designed to address the needs of runners and multi-sport enthusiasts alike:

Ultra-slim design: At just 11.5mm, the slim design of the watch module comfortably fits men and women, and all wrist sizes.

TomTom Multi-Sport includes all the features included in TomTom Runner, and also allows multi-sport athletes to track their distance, time, speed and other key metrics when they cycle or swim. The TomTom Multi-Sport is also enhanced with the following features and options:

Dedicated bike mount: Easily see key stats at-a-glance with the specially designed bike mount.
Cadence sensor: Track cadence, speed and distance, indoors and out.
Built-in altimeter: Accurately track elevation, ascent, descent and grade with the built-in barometric altimeter.
Swimming motion sensor: Check detailed swim metrics such as laps, strokes, time and speed, and calculate a SWOLF score to show swim efficiency.

The TomTom Runner and TomTom Multi-Sport will be available in Summer 2013.

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.

The app, called VRPETERS (Vehicle Rollover Prevention Education Training Emergency Reporting System), uses sensors and GPS capability built into smartphones that can detect rollovers. Once the app detects a rollover, it sends an automatic emergency e-mail and phone message with the coordinates of the accident location to family or emergency responders.

“The tractor is the main power source for field operations, and tractor rollover accidents have been killing people since the beginning of their use in agricultural production,” said Bulent Koc, assistant professor of agricultural systems management at MU and developer of the app. “More and more farmers are using their smartphones to monitor weather or calculate production inputs while operating machinery. Since they already have their phones with them, installing VRPETERS could help save lives.”

Data from the NIOSH show that one out of every 10 tractor operators will roll a tractor at least once. NIOSH also notes that only half of the 4.7 million tractors on U.S. farms have rollover protection. In order to minimize false alarm rollovers on the app, Koc and his research assistant Bo Liu designed a device that must be attached to the tractor. This device helps calculate the stability characteristics of the tractor and will provide a warning to the driver when the tractor approaches its rollover point.

“Many farmers think they can jump out of their tractors in the event of a rollover, but this isn’t the case usually,” Koc said. “Side rollovers can occur in just three-quarters of a second and most people need a second or more to react to an event. So, VRPETERS can benefit farmers when a rollover occurs because they often can’t reach their phones to make an emergency call.”

VRPETERS can benefit more than just farmers, as the app also can be used on construction vehicles, trucks, snowmobiles, military vehicles, riding lawnmowers and all-terrain vehicles.

In addition to the rollover device installed on tractors and other dangerous equipment, Koc and Liu designed another device that can be used with VRPETERS. This device can be installed on vehicles and can be used as a backup to stream data to a smartphone or tablet. “With this additional device, parents or fleet managers can obtain real time data on how machines are being used,” Koc said. “If the device detects improper operation, an intervention can occur before an accident happens.”

Initial testing of VRPETERS was done using a remote-controlled model tractor. Once fully tested on a standard tractor, Koc and Liu will look for an industry partner to market the app.

“We kept the design of the enhanced SPAN-CPT identical to our legacy product to ensure a seamless upgrade process for our customers who would like to take advantage of the improved positioning capabilities,” said Jason Hamilton, NovAtel director of marketing. “The enhanced SPAN-CPT is fully backwards compatible with the previous generation of product. It retains the same compact form factor with identical pin-out and log structure.”

As with the previous generation product, the upgraded SPAN-CPT integrates NovAtel’s precision receiver technology with fiber optic gyro and MEMS accelerometer inertial components from KVH Industries in one compact unit. The tight-coupling of the GNSS and INS technologies optimizes the raw GNSS and IMU data, delivering a superior position, velocity and attitude solution, NovAtel said. Comprised entirely of commercial components, the SPAN-CPT minimizes the operational complexities of working across international boundaries.

Production of the OEM6 supported SPAN-CPT begins June 1.
