MSRS «Loutch»

Multifunctional space relay system (MSRS) «Loutch» was developed by order of State Space Corporation ROSCOSMOS.

In December 2015 the system was put into operation. The operator and the communication complex developer is Gonets Satellite System, PC.

Multifunctional space relay system «Loutch» is designed to meet the challenges of information support for rocket and space equipment including the International Space Station (ISS RS), provision information exchange between TV-studios, facilitation telebridges, teleconferencing, reporting, and relaying SDCM GLONASS, COSPAS SARSAT, Rosgidromet data.

The MSRS «Loutch»orbit group consists of 3 geostationary relaying satellites «Loutch-5». «Loutch-5A» was deployed in 2011, «Loutch-5B» - in 2012, «Loutch-5V» - in 2014.
