Mission Details

Glonass-M n°61L

Uragan-M spacecraft are the second generation of GLONASS satellites with an increased lifetime of 7 years following up the first generation Uragan spacecraft.

GLONASS (Globalnaya Navigationnaya Sputnikovaya Sistema, Global Orbiting Navigation Satellite System) is a Russian space-based navigation system comparable to the American GPS system, which consists of Uragan spacecraft. The operational system contains 21 satellites in 3 orbital planes, with 3 on-orbit spares. GLONASS provides 100 meters accuracy with its C/A (deliberately degraded) signals and 10-20 meter accuracy with its P (military) signals.

The Uragan-M spacecraft are 3-axis stabilized, nadir pointing with dual solar arrays. The payload consists of L-Band navigation signals in 25 channels separated by 0.5625 MHz intervals in 2 frequency bands: 1602.5625 - 1615.5 MHz and 1240 - 1260 MHz. EIRP 25 to 27 dBW. Right hand circular polarized. On-board cesium clocks provide time accuracy to 1000 nanoseconds. A civil reference signal on L2 frequency was added after the completion of flight testing of Glonass-M in 2004 to substantially increase the accuracy of navigation relaying on civil signals.
