The Resurs-F was a photoreconnaissance spacecraft used to monitor Earth's natural resources (primarily those of the USSR). The spacecraft flew two types of mission configurations: (1) F1, which typically lasted two weeks and used three Kate-200 and two KFA-1000 camera systems, and (2) F2, which flew in a lower orbit than F1, typically lasted 3-4 weeks, and used the MK-4 camera system. The MK-4 was a multispectral visible wavelength camera which provided 5 to 8 meter resolution. The MK-4 operated at six wavelengths: 0.635-0.69, 0.81-0.9, 0.515-0.565, 0.46-0.505, 0.58-0.8, and 0.4-0.7 micrometers. The Kate-200 was a 200 mm focal length camera which operated at three wavelengths (0.5-0.6, 0.6-0.7 0.7-0.85 micrometers) with a resolution of 15 to 30 m. The KFA-1000 was a 1000 mm focal length camera with two wavelengths (0.57-0.68 and 0.67-0.81 micrometers) at 2 to 5 m resolution. The film camera systems were returned in 2.321 diameter spherical descent capsules, which were re-used approximately three times. The F2 mission was supported by solar panels which backed up the standard battery power supply. A stellar camera was provided on each mission for pointing.
