Yantar 1K

Version of the Yantar photo satellite for topographic mapping on behalf of the Red Army.

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.
