Inside GNSS • May/June 2013


Existing methods for improving the GNSS performance commonly attempt to enhance the signal processing and navigation estimation parts of a single receiver. Such approaches, however, leave unexplored the potential benefits inherent to the integration of data from multiple receivers.

BeiDou to Restart Satellite Launches Next Year, Shift B1 Signal Frequency after 2016

China will begin launching BeiDou-2 satellites again in 2013 as it begins its test program for the third generation of the nation’s GNSS program.

After launching 16 satellites since 2007 (including six last year) to establish the current regional constellation with 14 operational satellites and publishing an official interface control document December 27, China called a halt to further launches to evaluate the performance of the system and complete a development plan for the system.

IGS Launches Real-Time Service for High-Precision GNSS

The International GNSS Service (IGS), a worldwide federation of agencies involved in high-precision GNSS) applications, has announced the launch of its Real-Time Service (RTS).

The RTS is a global scale GNSS orbit and clock correction service that enables real-time precise point positioning (PPP) and related applications requiring access to IGS low latency products. The RTS is offered in beta as a GPS-only service for the development and testing of applications.

Letters: Get a Start on GNSS Interoperability Now

“The GNSS Quartet” (January-February 2013, Inside GNSS, aptly named and coauthored by Glen Gibbons, Dee Ann Divis, and Peter Gutierrez) is reminiscent of Dr. Brad Parkinson’s observation about “interchangeability” at his ION GNSS 2011 plenary session. With interoperability taken to its logical level of completion, a position solution should be readily obtainable from four satellites, each belonging to a different constellation.

GNSS Hotspots

Cape Canaveral and Plesetsk
√ [updated April 1] After three delays, a single GLONASS-M satellite will go up from Plesetsk space center on April 26. The United States will send up SVN66, the fourth GPSIIF satellite— on an Atlas V launcher for the first time—during the early evening of May 15. It had been delayed from March.

The PNT Boom

The navigation world is booming with new ideas at the moment to meet some of the greatest positioning challenges of our times. To realize demanding applications — such as reliable pedestrian navigation, lane identification, and robustness against interference, jamming and spoofing — we need to bring these different ideas together.

East Meets West: Hemisphere GNSS's New Era

Although not on the scale or at the strategic level of China National Offshore Oil Corporation’s takeover of Canada’s Nexen Inc., the recent acquisition of the Precise Products business of Hemisphere GPS by Beijing UniStrong Science & Technology Co. Ltd. marks a notable achievement in the GNSS world — the acquisition of a North American manufacturer with core GNSS receiver intellectual property by a Chinese enterprise.
