Loutch satellite system finally commissioned

The multifunctional data-relay system Loutch which is based on satellites designed and built by Information Satellite Systems – Reshetnev Company has successfully completed in-orbit flight tests.

Following the results of the test program that the system went through, the state commission decided to put it into service as from December 18, 2015.

The Loutch data-relay system enables data retransmission from the Russian segment of the International Space Station, manned and unmanned low-orbiting satellites when they are not visible from the Russian territory to the ground control centers and ground receiving stations. Additionally, data-relay satellites of the Loutch system are used to retransmit hydrometeorological data from the Russian Hydrometeorology and Environmental Monitoring Agency, signals of the International Satellite-Aided Search and Rescue System COSPAS-SARSAT as well as those of the Differential Correction and Monitoring System for GLONASS users.

The system’s space segment consists of Loutch-5A, Loutch-5B and Loutch-5V satellites manufactured by ISS-Reshetnev Company around its Express-1000 platform under a contract with the Russian Federal Space Agency. Satellites of the series have a 10-year designed lifetime and occupy the geostationary orbit. Three Loutch satellites were launched into orbit in the period from December 2011 to April 2014.
