Russian military communications satellite. Potok was one element of the second generation global command and control system (GKKRS) developed according to a decree of 17 February 1976. Military relay satellite built by NPO Prikladnoi Mekhaniki (NPO PM), Russia. Launched 1982 - 2000.

AKA: 11F663;Geizer;Geyzer;Sokol. Status: Operational 1982. First Launch: 1982-05-17. Last Launch: 2000-07-04. Number: 10 . Gross mass: 2,100 kg (4,600 lb).

The first of ten spacecraft was launched as Cosmos 1366 in 1982. These satellites were integrated with the Luch geostationary system and featured retransmission of high rate data retransmission in the centimeter wavelength range. While Luch handled communications between spacecraft and ground stations, Potok handled communications between fixed points and digital data from the Yantar-4KS1 electroptical reconnaissance satellite. Potok was the first communications spacecraft built by the Lavochkin design bureau. The Slav-2 and Sintez transponders aboard Potok were developed by G Ya Guskov at NPO Elas.

Potok was said by one account to have utilized the KAUR-4 spacecraft bus. This had an active 3-axis orientation system, with a single central body from which extended 40 square meters of solar panels. Its basic structure was that of the KAUR-3, but it was equipped with completely new systems: a digital computer, plasma station-keeping engines, hydrazine monopropellant orientation engines, and actively-scanned antennae arrays with 0.5 degrees antenna and 0.1 degree spacecraft pointing accuracy.

Potok transponders utilized a unique, hexagonal phased-array antenna. The principal ground stations for the Potok system were located at Nakhodka and in the Moscow region at Konakovo. From Geyser spacecraft positioned at 80 degrees E and 13.5 degrees W, the Potok system was designed for digital data transmissions in C-band. A third geosynchronous slot at 168 degrees West was never used. Mobile and stationary transmitter/receiver stations were used with antenna diameters of 2.6-3 m as well as compact phased-array antennas. In 1992 Russian officials offered the Geyser-Potok system for commercial international use under the name Sokol.

1976 February 17 - .

Energia; Buran; Mir; Luch; Potok approved; N1 formally cancelled. - . Nation: Russia. Spacecraft: Buran, Gamma, Luch, Mir, Mir-2, Potok.
Central Committee of the Communist Party and Council of Soviet Ministers Decree 'On work on Energia-Buran, DOS-7K nos. 7 and 8, Gamma. Geyzer (Potok), and Altair (Luch) and cancellation of the N1' was issued. The design of an improved model of the Salyut DOS-17K space station was authorised as part of the third generation of Soviet space systems in a decree. At that time it was planned that the two stations (DOS-7 and DOS-8) would be equipped with two docking ports at either end of the station and an additional two ports at the sides of the forward small diameter compartment. Luch and Potok were elements of the second generation global command and control system (GKKRS) deployed in the first half of the 1980's. Luch satellites, analogous to the US TDRS, provided communications service to the Mir space station, Buran space shuttle, Soyuz-TM spacecraft, military satellites, and the TsUPK ground control center. They also served to provide mobile fleet communications for the Soviet Navy. Additional Details: here....
