Global Navigation Satellite Systems Engineering, Policy, and Design
The 2015 World Congress of the International Association of Institutes of Navigation will take place at a new venue, the Corinthia Hotel, close to the well-preserved historical center of Prague, Czech Republic, on October 20 – 23, 2015. This will be the 15th meeting of all of the member organzations, who will discuss the science and practice of navigation and related technologies.

SIDEBAR: Michel Monnerat’s Compass Points
“I was born in Arles, in the south of France,” says Michel Monnerat, “but I left France before my first birthday. We moved many times, from place to place.”
Monnerat’s father worked for a civil engineering company, specializing in maritime works — harbor construction, coastal protection, and such. His family lived in Ivory Coast, Cameroon, and Tunisia, but Monnerat spent most of my early life in Lomé, the capital city of Togo.

Applanix Corporation announced that today (November 12, 2013) that the Trimble CenterPoint RTX correction service will be available across its entire airborne mapping portfolio.
Trimble CenterPoint RTX correction service is a GPS-, GLONASS-, and QZSS-enabled correction service built on Trimble RTX technology that provides high-accuracy GNSS positioning without the use of traditional reference station-based differential RTK infrastructure.

Tim Springer, PosiTim UGA common refrain in the world of GNSS is the desire for “interoperability,” the use of signals from multiple systems without a decline — and potentially even an improvement — in the quality of results.
Achieving this depends on large part in establishing comparable parameters — particularly the geodetic references and timing systems — among the GNSSs along with a dense network of ground reference stations that can provide continuous, precise monitoring of satellites’ orbital positions.

The eDLoran receiver including antenna is mounted in a standard enclosure (14x14x10cm) for GPS-RTK equipment provided by AD Navigation (Norway)The Dutch Pilots Corporation and Reelektronika announced today (January 7, 2014) the successful development and test of an Enhanced Differential Loran (eDLoran) backup to GNSS in The Netherlands.
Trials at sea and in the Rotterdam Europort harbor area met the requirement for absolute accuracies in the five-meter range, according to Durk van Willigen, CEO of Reelektronika, and Wim van Buuren, Loodswezen’s information & communications technology (ICT) and innovation manager and board member.

Lawmakers are poised to sharply limit the ability of foreign nations to own or control satellite system monitoring stations on U.S. territory, a rare show of congressional cooperation triggered by a Russian request to place stations supporting its satellite navigation system on American soil.

Editor’s Note: On November 19, Senator Roger Wicker (R-Mississippi), a member of the Senate Armed Services Committee, filed an amendment (No. 2185) to the FY 2014 National Defense Authorization Act (S. 1197),
Section 1082, that would limit the construction of satellite
positioning ground monitoring stations controlled by any foreign
government on U.S. soil. Such construction would require certification

GPS/BeiDou/MEMS configuration and GPS/MEMS configuration (left and right, respectively, top photo), Front view (center photo) and back view (lower photo) of nAX5.2Due to the huge success of GPS in both military and civil applications, several other GNSSs have been developed, built, and operated in the last few decades. GNSS, regional, and augmentation systems are comprise a growing family that also includes GLONASS, Galileo, BeiDou, and Japan’s Quasi-Zenith Satellite System (QZSS). New members, such as the Global Indian Navigation System (GINS), are preparing to join in next decade.

NovAtel Inc. has announced the NovAtel CORRECT positioning technology, which combines data from multiple GNSS satellite constellations with corrections from a variety of sources, to deliver the best position solution possible.
Designed for NovAtel’s OEM6 receivers, CORRECT capabilities can be implemented in three ways, with correction data delivered via satellite or Internet, depending on the requirements of the application: precise point positioning (PPP), TERRASTAR, or real-time kinematic (RTK).

Hemisphere GNSS has launched the Eclipse P306 and P307 multi-frequency GPS, GLONASS, and BeiDou modules, the first products to incorporate the company’s new SX4 ASIC.
With 372 channels, the modules can simultaneously track code and carrier phase signals on up to 89 satellites, are are Galileo- and QZSS-ready, and can be configured to address several diverse applications through software, according to the company.

JAVAD GNSS has introduced the Triumph-LS, a complete real-time kinematic survey system including an 864-channel receiver capable of receiving and processing all available GNSS signals, antenna, radio modem, controller, and collapsible pole. The receiver is based on JAVAD GNSS’s new Triumph 2 chip.
Trimble BD930 GNSS ModuleTrimble has introduced its BD930 module as part of its GNSS OEM portfolio.
This small module features triple-frequency support for GPS and GLONASS plus dual-frequency support for BeiDou and Galileo constellations. Capable of receiving a wide range of commercially available GNSS signals, the 220-channel BD930 takes advantage of all available signals to provide reliable RTK centimeter-level positioning.
