EGNOS Activates Safety of Life Service

On March 2, ESSP (the European Satellite Services Provider) declared the safety-of-life (SoL) signal from the European Geostationary Navigation Overlay Service (EGNOS) officially available for use by aviation, following European Commission (EC) authorization to provide the service.

Similar to the U.S. Federal Aviation (FAA) Administration’s Wide Area Augmentation System (WAAS), EGNOS transmits real-time corrections to GPS signals over a large expanse of Europe and north Africa.

Japan Researchers Use GPS Permanent Array to Find Large Position Shifts From Devastating Earthquake

Based on data from Japan’s GPS Earth Observation Network System (GEONET), researchers at the Geospatial Information Authority of Japan (GSI) reported today (March 14, 2011)  that the 9.0 magnitude Tohoku earthquake on March 11 in northeast Japan caused an estimated displacement of between roughly 6 and 28 meters along two fault blocks totaling nearly 400 kilometers (248 miles).

Beihang Authors Suggest TMBOC Design for China's Compass B1 Civil Signal

Despite the fact that China's rapidly developing global navigation satellite system now has seven spacecraft in orbit intermittently broadcasting test signals, it is the only GNSS provider that has not yet published a draft version of its interface control document (ICD), although one has reportedly been completed for more than a year.

Against that background, any new source of information about the directions of the Compass design — official, semi-official, or other — draws special attention.

Munich Satellite Navigation Summit 2011: GNSS in the Balance

Reprising its role as probably the premiere European conference for high-level discussions of positioning, navigation, and timing (PNT) policy, the Munich Satellite Navigation Summit set March 1–3 in Germany will highlight the Russian GLONASS system in a special session and address the plenary theme of “GNSS in the Balance.”

Russia’s First GLONASS-K In Orbit, CDMA Signals Coming

The first new-generation satellite GLONASS-K of the GLONASS navigation system has reached its targeted orbit, the Russian Federal Space Agency (Roscosmos) announced today (February 26, 2011).

The Soyuz-2.1b rocket lifted off from Plesetsk cosmodrome at 6:07 a.m. (Moscow time) this morning. The GLONASS-K spacecraft was carried into its planned orbit by a Fregat booster at 9:41 a.m. Moscow time, according to Roscosmos public affairs office, which reported that the satellite separated from the booster as planned.
