DESCRIPTION:A Roscosmos Soyuz rocket will launch the latest GLONASS-K navi
 gation satellite\, designated GLONASS-K1 №18L\, into medium Earth orbit 
 (MEO). The spacecraft is the 6th Uragan-K to be launched\, and overall the
  147th spacecraft of the GLONASS program. The rocket will fly in the Soyuz
  2.1b configuration with a Fregat-M upper stage.\n-\nGLONASS-K (Uragan-K) 
 spacecraft are the are the third generation of GLONASS navigation satellit
 es. The Uragan-K1 satellites have an increased lifetime of 10–12 years\,
  reduced weight of only 935kg and offer an additional L-Band navigational 
 signal. The payload consists of L-Band navigation signals in 25 channels s
 eparated by 0.5625 MHz intervals in two frequency bands: 1602.5625 - 1615.
 5 MHz and 1240 - 1260 MHz. EIRP 25 to 27 dBW. Right hand circular polarize
 d. On-board cesium clocks provide time accuracy to 1000 nanoseconds. A civ
 il reference signal on L2 frequency is to be added after the completion of
  flight testing of Glonass-M in 2004 to substantially increase the accurac
 y of navigation relaying on civil signals. A third civil reference signal 
 within the new frequency band of 1164-1215 MHz offered by the Glonass-K1 s
 atellite to enable civil airlines to use satellite-aided positioning as th
 e primary navigation facility. The new Uragan-K1 spacecraft also carries i
 nstrumentation of the KOSPAS-SARSAT international search-and-rescue system
 .\nGLONASS (Globalnaya Navigationnaya Sputnikovaya Sistema\, Global Orbiti
 ng Navigation Satellite System) is a Russian space-based navigation system
  comparable to the American GPS system\, which consists of Uragan spacecra
 ft. The operational system contains 21 satellites in 3 orbital planes\, wi
 th 3 on-orbit spares. GLONASS provides 100 meters accuracy with its C/A (d
 eliberately degraded) signals and 10–20 meter accuracy with its P (milit
 ary) signals.
