Roscosmos has confirmed a successful launch of three GLONASS-M satellites on March 1 at 21:19 UTC. The satellites were released from the upper stage at 00:52 UTC on March 2. This launch was the Block 40 GLONASS launch postponed from September 2009. More>>

Adding GLONASS to GPS gives a total of about 50 satellites, for a significant improvement in navigation availability, reliability, robustness, and convergence time through a new multi-GNSS precise point positioning (PPP) service. System performance and field results demonstrate that there is no...More>>

The three new GLONASS-M satellites launched on December 14 have been set operational: GLONASS 730 in orbital slot 1, was set healthy on January 30. This brings to 18 the number of satellites currently in service, although GLONASS 722 continues to provide a healthy signal only on its L1 frequency....More>>

Spirent Communications plc today introduced a testing capability for assisted GLONASS (A-GLONASS) on UMTS mobile devices and chipsets. Supported on Spirent’s 8100 UMTS Location Technology Solution (ULTS), the new A-GLONASS testing capability gives early adopters of A-GLONASS a competitive edge...More>>

The Russian space agency Roscosmos launched a venerable Proton rocket carrying three GLONASS-M satellites into orbit on December 14. Each 3,000-pound satellite is designed to last seven years. They join a constellation numbering 19 satellites, although only 16 are healthy. PLUS: Loran and Galileo...More>>

Although falling short of its goal of global service — read 24 operating satellites on orbit — in the near term, GLONASS’s heroic catch-up effort should inspire cautious confidence among manufacturers. More is needed, but this measure of optimism should encourage companies to keep plans for...More>>

The Russian space agency Roscosmos launched a venerable Proton rocket carrying three GLONASS-M satellites into orbit on December 14. Each 3,000-pound satellite is designed to last seven years. They join a constellation now numbering 19 satellites, although one of those is about to be decommissioned...More>>

Four Galileo in-orbit validation (IOV) satellites scheduled to launch next year have already missed their first pad date.The European version of Russia’s Soyuz rocket is now scheduled to carry the four IOV satellites into orbit in two launches in November 2010 and early 2011, as announced by...More>>

A planned late-September launch of a three new GLONASS-M satellites from the Baikonur space center was postponed due to a problem with signals emanating from a previously launched GLONASS-M satellites, now on orbit. Initially, a new launch date of October 29 was set by Roscosmos, the Russian space...More>>

Just a few observations, as of mid-day Thursday: Attendence by the non-US satellite providers was rather disappointing, save for the Gallileo and QZSS contingents. What was to be a panel presentation by spokepersons from the various foreign systems under development was rather abbreviated, with...More>>
