The Leica Nova MS50 MultiStation combines every significant measuring technology in one device for the first time, Leica said. Precision 3D scanning, extensive and precise total station capabilities, digital imagery and GNSS connectivity are brought together in the multistation. The new mergeTEC technology fuses hardware capabilities with comprehensive data-management solutions. Images are synchronized with scans, and scans are tied into total station measurements, making it easy to manage complex 3D data, Leica said.

The Leica Nova MS50 integrates 3D point cloud measurements into regular survey workflows. Users can collect and visualize their topographic survey data with detailed high-precision scans. They save time by computing results and verifying the integrity and completeness of data immediately in the field, avoiding costly reworking or returns. Ultimately, users benefit from better decisions with richer and more detailed data.

Also part of the innovative new Leica Nova solution are the Leica Nova TS50 high-precision total station and Nova TM50 monitoring station.

The Leica Nova TS50 high-precision total station has 0.5-inch angular accuracy and an optimum combination of angle and distance measuring. Integrated overview and telescope cameras with fatigue-reducing autofocus document the scene with high-quality photogrammetric images using the latest SmartWorx on-board software.

The user sees on the remote control display exactly what the Leica Nova TS50 sees, allowing for easy one-person data capture. The Leica Nova TS50 allows full control through “tap and turn” without the need to go to the instrument and back again. The 20-Hz live video stream can be combined with a graphical overlay for cost-effective recording with immediate clarification of ambiguous situations. Together with the benefits of GNSS connectivity, the Leica Nova TS50 offers complete versatility by delivering reliable results, Leica said.

For critical monitoring tasks, the new Leica Nova TM50 monitoring station provides the highest angle accuracy and offers short measurement cycles through high speed Piezo drives and a fast, highly accurate EDM. The Leica Nova TM50 includes 0.5″ angular accuracy and can measure up to 3’000 meters, which makes it the ideal sensor for monitoring tasks in mines, landslides, etc. For additional documentation, the monitoring sensor includes an overview camera and a telescope camera with 30x magnification and autofocus. The Leica Nova TM50 meets the challenge of 24-hour-a-day, 7-days-a-week monitoring applications. The Leica Nova TS50/TM50 instruments are IP65 rated and designed to withstand the roughest use in the most severe environments.

Leica GeoMoS 6.0 enhances conventional monitoring methods with automatic scanning of surfaces with the Leica Nova MS50 MultiStation.

The Leica software portfolio includes the following:

• With the new Leica Infinity software, users can seamlessly manage, visualize, process and georeference combined total station, imaging and scanning data from the Leica Nova MS50 MultiStation and other Leica Geosystems sensors.
• For AutoCAD users who have never before worked with rich point clouds or 3D datasets, the new Leica MultiWorx for AutoCAD plug-in software offers a simple way to integrate point cloud processing into existing workflows.
• Leica Cyclone and Leica GeoMoS as well as numerous other software packages from partners such as MicroSurvey and Listech can also be integrated into the workflow to meet specific needs.

The C-Tides suite combines the vertical accuracy of C-Nav’s GNSS Precise Point Positioning service with the latest advanced ocean and coastal tides models, the company said.

C-Tides Online features real-time filters and vessel dynamics, a choice of worldwide Mean Sea Surface or regional reference frame models, and tidal prediction for mission planning.

C-Tides Offline utilities include data smoothing and outlier rejection, harmonic analysis, Doodson X0 filter, and a LAT option.

“It’s been a privilege working with our academic partners to develop what is probably the worlds’ most advanced real-time GNSS tide solution,” said Russell Morton, C-Nav head of development.

C-Tides is a fully supported C-Nav utility. The results are suitable for combining with other suitably calibrated vertical components to achieve IHO SP44 Order 1 or better.

Initially, wireless carriers deployed 4G/LTE solely for data use. Without VoLTE9-1-1 capabilities, carriers must process emergency calls over 3G networks (circuit-switched fallback), even in areas where LTE is deployed. However, with TCS’ VoLTE9-1-1 service, they can now process 911 calls in an all-LTE environment, enabling them to reclaim or reuse 3G spectrum.

“As carriers increasingly move toward LTE networks, the ability to handle 911 emergency communications is critical,” said Thomas Ginter of TCS. “By leveraging VoLTE9-1-1, network operators are helping to ensure subscribers receive the responsiveness they need in an emergency situation, while expanding coverage to areas where 3G coverage is lacking.”

TCS VoLTE9-1-1 features:

• Call routing to the PSAP: The TCS VoLTE9-1-1 service routes a 4G/LTE-originated 911 call using coarse location via the route determination function component.
• PSAP telecommunicators can call back if disconnected: The TCS VoLTE9-1-1 service remains fully backwards compatible, supporting necessary functions such as providing PSAPs with full 10-digit subscriber callback numbers.
• Re-bid by a PSAP for precise location after call routing: The location retrieval function allows a wireless carrier complete flexibility in choosing its underlying high-accuracy location technology and supports updated/precise position requests.
• Emergency voice call continuity for location service: Location continuity and location delivery to the PSAPs are supported in usage scenarios where the 911 call switches from 4G/LTE to 3G/2G networks.
• Expansion beyond voice: As wireless networks advance, multimedia objects such as text, audio and video can be transferred to a compatible termination point with LTE IP networks, for example, an NG ESINet and i3 PSAP. Leveraging an all-IP network makes it easier and more cost effective to interconnect services.
• Small cell support: The TCS VoLTE9-1-1 solution supports small cells, including femtocells, microcells, and picocells, which are now commonly used in dense urban, indoor areas and enterprise networks.

TCS supports half of all U.S. wireless E911 calls, serving more than 140 million wireless and IP-enabled devices.  The company holds more than 280 patents, 43 of which relate to public safety, and more than 360 pending worldwide.

MAX-M5Q: ideal positioning solution for industrial M2M and Russia’s ERA-GLONASS emergency call system.

Swiss u-blox introduces the surface-mount MAX-M5Q, a compact satellite positioning module that supports GPS and GLONASS, as well as Japanese QZSS satellite GNSS systems. High-performance GPS/GLONASS parallel operation is also supported to enhance positioning speed and accuracy.

Designed for use in rugged environments and wide temperature range, MAX-M5Q is intended for industrial machine-to-machine (M2M) applications as well as Russia’s ERA-GLONASS emergency call system. MAX-M5Q enhances positioning in poor GNSS satellite visibility conditions as well as in high latitude and polar regions, u-blox said.

“With parallel GPS/GLONASS operation, MAX-M5Q is able to track all 50 and more U.S. and Russian satellites to deliver incomparable speed, accuracy, and positional availability,” said Thomas Nigg, vice president of Product Marketing at u-blox, “Its compact size and high-reliability makes it an ideal positioning solution for mobile resource management and ERA-GLONASS emergency call applications.”

With dimensions of 9.7 x 10.1 x 2.5 mm, MAX-M5Q is the newest member of u-blox’ MAX GNSS LCC module series. Additional features include autonomous A-GPS that reduces warm start TTFF by as much as 90%, and an embedded data logger which can store location information to internal Flash memory for up to 16 hours at 15 second intervals.

Smith’s photograph was taken at 21:58:38 UTC (start) with a Canon EOS 450D Digital Rebel camera with an 18-55mm zoom lens. The camera settings were: focal length 55mm, aperture f/5.6, and an exposure of 8 seconds at an ISO value of 1600. Two images are shown below: the original, as obtained from the camera, and a greyscale image with edge enhancement.

The Centaur can be seen traveling left to right and starts its track as it crosses the constellation of Cygnus. There’s a slight wobble at the beginning as the shutter release was pressed. The glow at the bottom of the frame is from a streetlight. The elevation angle of the Centaur was approximately 12 degrees.

SVN66 will operate as PRN27 and it will eventually occupy the C-2 orbital slot, replacing SVN33/PRN03, a Block IIA satellite launched in 1996. SVN66 is currently in a drift orbit about 400 kilometers above the operational constellation. It should reach the C-2 slot within a few days from now. The satellite has already been added to the broadcast almanac although it has not yet started to transmit standard signals. It is currently marked as unhealthy in the almanac and will remain so, even after standard signals are switched on, until testing is completed sometime this summer.

A U.S. Air Force Global Positioning System satellite built by Boeing was successfully launched May 15. The fourth GPS IIF satellite, Space Vehicle Number (SVN) 66, was carried aboard a United Launch Alliance Atlas V Launch Vehicle at 5:38 p.m. EDT (21:38 UTC) May 15 from Cape Canaveral Air Force Station, Florida.

The new capabilities of the IIF satellites will provide greater navigational accuracy through improvements in atomic clock technology; a more robust signal for commercial aviation and safety-of-life applications, known as the new third civil signal (L5); and a 12-year design life providing long-term service. These upgrades improved anti-jam capabilities for the warfighter and improved security for military and civil users around the world, the Air Force said in a statement.

The Atlas rocket took off on schedule. The satellite was released from the Centaur upper stage at T+ 3 hours, 23 minutes and 52.8 seconds or about 01:02 UTC on May 16. Details on the Block IIF satellites and the Atlas rocket can be found here.

“I’m extremely pleased with today’s launch and delighted to be part of this mission that enhances our nation’s critical GPS capability. Thanks to the superb efforts of the of the 45th and 50th Space Wings, United Launch Alliance, our industry partners, the Atlas V and GPS IIF launch teams, the GPS IIF-4 mission was successfully carried out,” said Col. Bernie Gruber, director of the Space and Missile Systems Center’s Global Positioning Systems Directorate.

“The GPS constellation remains healthy and continues to meet and exceed the performance standards to which the satellites were built. Our goal is to deliver sustained, reliable GPS capabilities to America’s warfighters, our allies and civil users around the world, and this is done by maintaining GPS performance, fielding new capabilities and developing more robust modernized capabilities for the future,” said Colonel Gruber.

Here are videos of the launch:

Sun Jiadong, chief designer of BDS and an academician of the Chinese Academy of Sciences, made his comments in an interview with The Beijing News, as reported by the Chinese government’s website.

He added that this compatibility is the only way to ensure the protection of national information. “Safety issues abound in economic areas,” said Sun. “Ordinary people may have few concerns about the security of information but it is of vital significance.”

The development of Beidou also largely depends on the government’s involvement. “Even though the enterprises spare no effort in developing the system, the products they make would not be available for mass production, which will in turn be reflected by the prices. The government has to promote the research and development of the system,” Sun said. Sun cited the governments of Beijing, Shanghai, and Guangzhou as examples of local governments that were effectively helping to develop the BDS.

The use of Beidou could go beyond basic navigation functions and extend to the civilian market. It would take longer for the BDS to be available for civilians, said Sun. The use of Beidou on mobile phones relies on the development of a small and power-efficient chip. Otherwise the phone cannot be used.

When asked about when and how the cost of developing the BDS will be recovered, Sun reiterated that Beidou was developed to ensure the security of national information, and not to make profits.

The Beidou global navigation system will be available by 2020 with the launching of more than 30 satellites.
