It will be in geosynchronous orbit. LuchLuch 5A is one of a planned three Luch relay satellites. Luch 5B was launched on 2 November 2012 and Luch 5V is expected in 2013 or 2014.[3] They are dual purpose satellites with both military and civil uses, and are similar to those in the US Tracking and Data Relay Satellite System.[6] Luch 5A was built by JSC Information Satellite Systems using the Ekspress-1000A bus. It has 6 S and Ku band channels with repeaters manufactured by Thales Alenia Space and other equipment manufactured by Sumitomo. The Ku band antenna operates at up to 150 Mbit/s and the S band antenna at up to 5 Mbit/s. The satellite also relays COSPAS/SARSAT signals and Planet-S System data.[3][8][8][10][11][12] The satellite is designed to relay data from the ISS, satellites in low earth orbit and rocket launch vehicles.[10] Luch 5A is located at 167° E. LaunchLuch 5A was launched on 11 December 2011 with satellite Amos-5. The Proton-M rocket with a Briz-M upper stage launched from Baikonur Cosmodrome launchpad 81/24 at 11:17 UTC. After four burns of the Briz-M upper stage it was placed into geosynchronous transfer orbit.
