The Kondor-FKA is a small civilian radar Earth observation satellite designed by NPO Mashinostroyeniya as a civilian counterpart to the Kondor-E satellite. The Kondor satellite features a S-band synthetic aperture radar (SAR), which can conduct both continous swath surweys or detailed spot surveys. The swath width is 10 km. Ground resolution is 1 to 2 m in spotlight mode, 1 to 3 m in stripmap mode and 5 to 30 m in ScanSAR mode.
The 2.1a version includes conversion from analog to digital flight control system and uprated engines on the booster and the first stage with improved injection systems. The new digital flight control and telemetry systems allow the rocket to launch from a fixed rather than angled launch platform and adjust its heading in flight. A digital control system also enables the launch of larger commercial satellites with wider and longer payload fairings such as the ST-type fairing. These fairings introduce too much aerodynamic instability for the old analog system to handle.
