By Inside GNSSThe Federal Aviation Administration (FAA) has awarded Raytheon Company a two-year contract extension to continue to provide services for the Wide Area Augmentation System (WAAS). The $30.1 million contract extends the period of performance through Sept. 24, 2013.

The navigation message has always been considered an inherent and essential feature of a global satellite navigation system. Its primary objective is to provide receivers with information on the errors of satellite clocks and parameters to compute the positions of satellites, as well as other parameters that help generate more accurate measurements.
By Inside GNSS[Update November 9 2011] In an ex parte filing with the Federal Communications Commission (FCC) on November 8, a leading GPS advocacy group has asked that the agency “promptly rule” that LightSquared not be permitted to pursue high-powered terrestrial operations in the upper Mobile Satellite Services (MSS) band adjacent to the GPS L1 band.
By Inside GNSSFollowing a difficult 2009, the precision GNSS market is moving into a new period of sustained growth, resulting in a near doubling of shipments and revenues by 2016, according to recently completed study by ABI Research.
By Inside GNSS[Updated September 2, 2011] Amid White House efforts to keep a lid on the process and congressional hearings on the subject, the controversy surrounding LightSquared’s interference to GPS could compel the Federal Communications Commission (FCC) to require another round of testing — this time of the wireless broadband company’s lower L-band frequencies.
By Inside GNSSThe gloves have come off now that test results show clearly the probable effects on GPS of LightSquared’s proposed wireless broadband network: widespread, debilitating interference to GPS receivers.
By Dee Ann DivisInterference can pose a threat to the reception of GNSS signals in a variety of ways. Even low-level signals have the potential to interfere with GNSS receivers, which require very high sensitivity for acceptable performance due to the extremely low received GPS signal power at the Earth’s surface.
By Inside GNSSResearch released yesterday (June 22, 2011) indicates that interference from LightSquared cellular broadband transmitters could cost manufacturers and users of commercial GPS technology up to $96 billion in annual losses.
By Inside GNSSHemisphere GPS, Inc., has reported revenue growth of 41 percent and a return to profitability in the first quarter of 2011 for the three months ending March 31.
For the quarter, the Calgary, Alberta, Canada–based company generated $21.2 million in total revenues, compared to US$15.1 million in the first quarter of 2010. Revenues from all market segments increased in the first quarter of this year.
