Potok

Potok is an element of the second generation Soviet global command and control system. Potok satellites are integrated with the Luch system – the latter handling communications between spacecraft and ground stations, the former handling communications between fixed points and digital data from the Yantar-4KS1 electro-optical reconnaissance satellite. About 10 Potoks have been placed in GSO between 1982 and the present by Proton-K launch vehicles from Baikonur.
