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.
| Band | Frequency (GHz) | Resolution (m) |
| SAR-3 (X) | 3.49 | 5-7 |
| SLR-3 (X) | 3.49 | 1200-2000 |
| SAR-10 (S) | 9.58 | 5-7, 15, 30 |
| SAR-70 (L) | 70 | 30 |
| Band | Wavelength Region (µm) | Resolution (m) |
| 1 | 0.5-0.6 (green) | 10 |
| 2 | 0.6-0.7 (red) | 10 |
| 3 | 0.8-0.9 (NIR) | 10 |
| Band | Wavelength Region (µm) | Resolution (m) |
| 1 | 0.5-0.6 (green) | 170 |
| 2 | 0.6-0.7 (red) | 170 |
| 3 | 0.7-0.8 (NIR) | 170 |
| 4 | 0.8-1.1 (NIR) | 170 |
| 5 | 10.3-11.8 (TIR) | 600 |
Unknown at this time. The satellite has not been launched.
