Russia Places 3 GLONASS Satellites in Orbit

Russia successfully launched three modernized GLONASS (GLONASS-M) satellites from the Baikonur Cosmodrome in Kazakhstan on October 26, a day later than planned due to a Kazakh national holiday. The Proton-K rocket, equipped with a Block DM upper stage and carrying three Uragan-M (GLONASS-M No. 18, 19, 20) satellites, lifted off at 11:35 Moscow time.

GLONASS Launch Is Back On for October 25

Investigation into a Proton-M rocket failure in September, which appeared to threaten the schedule for continued rebuilding of the GLONASS constellation, has cleared the launcher and Baikonur facility for renewed activity, including a scheduled October 25 launch of three GLONASS-M satellites.

Successful GPS Block IIR-M Spacecraft Launch

A Block IIR-M GPS satellite was launched successfully today (October 17, 2007) from Cape Canaveral Air Force Station, Florida. Expected to be set healthy for use in early November 2007, the spacecraft will be designated as PRN15/SVN55, referring to its pseudorandom noise code and space vehicle number, respectively.

Lack of Launcher Module Delays Galileo Launch

Unavailability of an upper stage of the Soyuz launcher will delay launch of the second Galileo In-Orbit Validation Element satellite (GIOVE-B) until at least March 2008. The most recent schedule had called for a late-December launch from the Baikonur Space Center in Kazakhstan.

Already behind schedule as the result of an electrical short that caused widespread damage to the spacecraft during laboratory tests in summer 2006, the Galileo program’s latest postponement reportedly stems from the lack of a Fregat module. Fregat is the portion of the Russian rocket that releases the spacecraft into its final orbit (shown with GIOVE-A in accompanying ESA photo).

Transport Ministers Leave Galileo Procurement Unresolved

The European Transport Council generally reaffirmed its commitment to the Galileo program in an October 2 meeting without resolving some underlying differences of how to finance the system following abandonment of the public-private partnership (PPP) approach earlier this year.

In its first look at the European Commission (EC) plan to complete the system by 2013 under a more traditional public procurement process, the council confirmed its intention “to take an integrated decision on the European GNSS before the end of the year.”

GLONASS has "preliminary approval" to transmit CDMA GLONASS signals at L1, L5

GLONASS has gotten “preliminary approval” to add code division multiple access (CDMA) signals to future satellites.

Since its initiation in the early 1980s, the Russian GNSS system has employed frequency division multiple access (FDMA) techniques in which the same code is used for the signals broadcast by the system, with individual spacecraft being distinguished from one another by a specific frequency allocation. Russia would almost certainly continue broadcasting FDMA signals on existing frequencies.

USAF evolves GPS architecture with $800 million upgrade to ground control segment

On September 14, Air Force crews at Schriever AFB, Colorado, completed the initial phase of an $800 million upgrade to the GPS operational control segment.

Operators in the 2nd Space Operations Squadron (2SOPS) of the USAF 50th Space Wing migrated control of the GPS satellite constellation and ground monitoring facilities from a 1970s-era mainframe computer to a distributed IT infrastructure with advanced automated features. The 50th Space Wing, through the 2nd SOPS, performs the satellite command and control mission for the Global Positioning System.
