Sensor Specifications: Almaz-1B

The successor to the Almaz-1 mission, Almaz-1B, was initially set for launch at the end of 1998; the new launch date is unknown. The satellite will have a polar, circular, sun-synchronous 400-km orbit. Almaz-1B will carry the following sensor packages: the On-board Radar Complex, the Selva Opto-electronic Equipment, and a LIDAR instrument. The On-board Radar Complex consists of the SAR/SLR-3, SAR-10, and SAR-70. The SAR/SLR-3 instrument can operate either as in SAR or side-looking radar. The Selva Opto-electronic Equipment consists of the MSU-E, MSU-SK, and Spectro-Radiometer for Ocean Satellite Monitoring (SROSM). The specifications for the MSU instruments are below. The SROSM has eleven channels from 0.42 - 12.5 µm at 600-m resolution; wavelengths are unknown at this time.
