Cosmos 2454

It is a satellite of the Parouss constellation. These are military positioning satellites, used to give the position of Soviet and Russian submarines and ships. They have an accuracy of 100 meters, and are still operational today.

The Sterkh satellites are to replace the Nadezhda series in the international Search and Rescue Satellite-Aided System (COSPAS-SARSAT). Unlike the Nadezhda precursors, the Sterkh series does not provide navigation services, which has been taken over by the GLONASS system. Therefore the satellites can be much smaller and were launched piggy-back on other LEO missions.
