Loutch-5A satellite in the COSPAS-SARSAT system

A repeater which is part of the COSPAS-SARSAT payload carried by ISS-Reshetnev’s Loutch-5A data-relay satellite was switched to operational mode.

The decision to commission the distress beacon signal repeater was made at the COSPAS-SARSAT Secretariat meeting following the positive results of its in-orbit testing. The tests had been carried out at the ground receiving stations located in New Zealand and Khabarovsk (Russia).

Geostationary satellites which are equipped with payloads of the International COSPAS-SARSAT system enable real-time tracking of distress signals transmitted by radio beacons (aviation, maritime and personal use), locating their position and further transmitting this information to rescue services and the appropriate Rescue Coordination Centers. Distress signals are received and transmitted at 406 MHz.

The Loutch-5A satellite carries COSPAS-SARSAT payload and is stationed in the geostationary orbit at 167 degrees East. It enables real-time data communication between the ground and low-orbiting satellites, launch vehicles, upper stages, and the Russian segment of the International Space Station. Additionally, data-relay satellites of the Loutch series 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.
