Russians Bring Latest Trio of GLONASS Satellites On Line

Three GLONASS-M satellites launched March 2 began transmitting healthy navigation messages today (March 28).

The Russian GNSS operational constellation now includes 23 spacecraft, including two spares in orbital plane III, slots 22 and 23, as well as GLONASS space vehicle 716, which remains in maintenance status with a malfunctioning signal generator.

Russia Launches 3 GLONASS-M Satellites

[Updated 03:35 GMT, March 2] Russian Space Forces successfully launched three GLONASS satellites from the Baikonur launch site in Kazakhstan on March 2, at 00:19 Moscow time (22:19 GMT, March 1).

The launch had been postponed from last September after an anomaly was discovered in one of the on-orbit space vehicles (SVs) navigation payload.

GLONASS Gets Its Groove Back — 19 Satellites on the Air

[UPDATED Feb. 8, 2010] The Russian GNSS system, GLONASS, has brought its contingent of transmitting satellites back up to 19, as spacecraft launched in December and others off-line for maintenance have returned to healthy status.

Meanwhile,  Voice of Russia, the Russian government's international radio broadcasting service, has reported that a monitoring station is being established at the Russian Antarctic outpost of Bellingshausen to track GLONASS  satellites. The orbital planes in the constellation are oriented so that GLONASS spacecraft pass over higher latitudes in the northern and southern hemispheres than do the other GNSS systems.

Three GLONASS-M Satellites Launched in December, All Operational as of February 1

(UPDATED FEB. 1, 2010) Russia got its GNSS program back on track with the December 14 launch of three modernized GLONASS-M satellites — resuming a schedule interrupted by problems with a navigation payload on an in-orbit spacecraft. A Proton launcher took the trio of satellites into orbit at 1038 GMT (5:38 a.m. EST) from the Baikonur Cosmodrome in central Kazakhstan.The first of the new spacecraft began transmitting signals on January 10. Another went live on January 24 and the third was declared operational in a February 1 ITAR-TASS press release.
