Luch 5V (Russian:Луч-5В meaningray and sometimestransliterated asLoutch-5V) is a RussianLuchrelay satellite which transmits data from theRussian Orbital Segment of theInternational Space Station, and from other satellites inlow Earth orbit. It currently is stationed in the 95° Eastgeosynchronous orbit slot of the Luch network.
Luch 5V is the third of theMKSR Luch Constellation.Luch 5A was launched on December 11, 2011, andLuch 5B 2 November 2012.[2][4] They aredual purpose satellites with both military and civil uses, and are similar to those in the USTracking and Data Relay Satellite System.[5]
Luch 5V was built byJSC Information Satellite Systems using the Ekspress-1000A bus, and is an almost clone of the Luch 5A. The only differences are some structural designs that had to be adapted for its companion to orbit,KazSat-3.[6] It has 6S andKu band channels with repeaters manufactured byThales Alenia Space and other equipment manufactured bySumitomo. The Ku band antenna operates at up to 150Mbit/s and the S band antenna at up to 5 Mbit/s. The satellite also relaysCOSPAS/SARSAT signals and Planet-S System data.[2][7][8][9][10]
The satellite is designed to relay data from the ISS, the newSoyuz-MS andProgress-MS spacecraft, satellites in low earth orbit and rocket launch vehicles.[7][3][11]
Luch 5V was launched on 28 April 2014 on a dual launch withcommunication satelliteKazSat-3. TheProton-M rocket with aBriz-M upper stage launched fromBaikonur Cosmodrome launchpad81/24 at 04:25 UTC. After five burns of the Briz-M upper stage it was placed intogeosynchronous orbit.[3][1][12]
