Luch
Luch 5B is one of three Luch relay satellites. Luch 5A was launched on 11 December 2011 and Luch 5V was launched on 28 April 2014.[2] 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.[3]
Luch 5B was built by JSC Information Satellite Systems using the Ekspress-1000A bus. It has 4 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 has a "laser-radio channel".[2][4][5][6][7][8]
The satellite is designed to relay data from the ISS, satellites in low earth orbit and rocket launch vehicles.[5][7]
Luch 5B is located at 16° W.
Launch
Luch 5B was launched on 2 November 2012 with satellite Yamal 300K. It was launched from Baikonur Cosmodrome launchpad 81/24 by a Proton-M rocket with a Briz-M upper stage. It was launched at 21:04 UTC and after four burns of the Briz-M upper stage it was placed into geosynchronous transfer orbit at 06:33 UTC on 3 November.[1]
The launch was delayed from 30 August 2012 due to the failure of the launch of Telkom-3 and Ekspress MD2 in August 2012.[1]
