Yantar 1K
Yantar 1K

Russian military surveillance satellite. Version of the Yantar photo satellite for topographic mapping on behalf of the Red Army. Area Reconnaissance, photo (film return type) satellite built by TsSKB for GRU, Russia. Launched 1981 - 2005. Used Yantar Bus, Zenit reentry module.

AKA: 11F660;Kometa;Siluet;Spin-2. Status: Operational 1981. First Launch: 1981-02-18. Last Launch: 2005-09-02. Number: 21 . Gross mass: 6,600 kg (14,500 lb).

The Yantar-1KF system was intended to build up high precision maps based on information from the Zenit-4MT. However it became impossible to keep the spacecraft within the weight that the Soyuz-U launch vehicle could lift. It would require a Proton or Zenit vehicle. Therefore the spacecraft was cancelled.

A complete design revision beginning in 1973 led to a production version of the Yantar photo satellite for topographic mapping for the Army General Staff. The revised satellite was developed in accordance with a resolution of 3 February 1977. Camera development began in the 1980's and flight trials began in 1981. The Yantar-1KFT was equipped with the Yakhont-1 TK-350 topographic camera and an APO-Oktan-8 objective, a product of the Byelorussia Optical Camera Company. These provided a focal length of 350 mm, with photo negative size of 300 x 450 mm, covering an area of 200 x 300 km with a resolution of 10 m and a scale of 1:660,000. The camera was designed for exceptional geometric precision for cartographic purposes and each image overlapped the next by 60% to 80% to allow stereoscopic pairs to be made. Closeup images were made by the KVR-1000 camera with a focal length of 1000 mm, a negative size of 180 x 180 mm covering an area of 40 km x 40 km at 1:50,000 scale and 2 m resolution. Western description: Fourth generation topographic. Typical orbital profile: inclination 64.9 degrees with an altitude of 207-270 km. Designed duration: 40 days. First flight: Cosmos 1246. Last flight: Cosmos 2284. Transmission frequencies observed in West: 150.3 PCM-FM; 400.8 CW.
