High orbit laser satellites “Etalon-1, -2”

The Etalon high-orbit laser satellite consists of 2146 corner reflectors and is designed to reflect radiation from a quantum optical station. Satellite ranging with “Etalons” made it possible to study the effects of forces on the satellite orbits of the GLONASS system.

The satellites are currently used by the international laser ranging service for geodetic and navigation applications.
