The GPS program continues progress on several fronts — in space and on the ground.
During fall 2010, the U.S. Air Force and the Raytheon Company team developing the GPS Advanced Control Segment (OCX) successfully carried out an integrated baseline review (IBR) for the next-generation system on schedule.
When completed in 2015 under the current schedule, GPS OCX will deliver control segment enhancements designed to provide secure, accurate and reliable navigation and timing information to military, commercial and civil users.

Soyuz launch of IOV satellite. ESA illustrationEurope’s Galileo space-based navigation system still awaits launch of its first in-orbit validation (IOV) satellites — now set for August 2011 — but the program is rolling out a steady stream of announcements of milestones reached.
Most recently, European Commission (EC) and European Space Agency (ESA) officials inaugurated the Fucino Galileo Control Center, 130 kilometers (81 miles) east of Rome, which will be responsible for the Ground Mission Segment.

GMV will launch the SRX-10, a software GPS receiver for mass-market applications, at this year’s GSMA Mobile World Congress, scheduled February 14–17 in Barcelona, Spain.
As a fully hosted solution, all SRX-10 receiver functions — even signal acquisition and tracking — can be hosted on a general purpose CPU with only the requirement of adding on a low cost RF front-end, according to the company.
The company cites other benefits offered by its new software receiver, particularly its substantial flexibility and upgradeability.
Proton rocketThe recent loss of three GLONASS-M satellites in space resulted from a series of mistakes made by the Russian Energia rocket corporation, the head of the Russian state commission probing the incident said today (December 17), according to the state news agency RIA-Novosti.

China successfully launched the seventh BeiDou-2 satellite — the second inclined geostationary orbit (IGSO) — today (4 a.m., December 18 local time) from the Xichang Satellite Launch Center in Sichuan province.
In 2010 China added five spacecraft to its constellation.

Workers place the satellite fairing for the seventh BeiDou-2 satellite atop a Long March IIIA rocket at Xichang Satellite Launch Center, in southwest China’s Sichuan ProvinceChina is preparing for launch of another satellite in its Compass/BeiDou-2 GNSS system in the "coming days," according to an unnamed spokesperson at the Xichang Satellite Launch Center in southwest China’s Sichuan Province.
According to earlier news reports, this will be the second of five inclined geosynchronous orbiting (IGSO) spacecraft planned for the regional version of the system that China hopes to complete by 2012. The full (Phase III) constellation will contain only three IGSOs.

A Proton rocket carrying three modernized GLONASS (GLONASS-M) satellites failed to reach orbit following its launch Sunday (December 5, 2010), falling into the Pacific Ocean.
The Russian Federal Space Agency (Roscosmos) said that a special board had been established to investigate the event — rare for the GLONASS program — and "define next steps."
