“Komparus” automated radio-engineering satellite control system
PURPOSE of the SYSTEM
The system is intended for spacecraft control and ensures automated control of a spacecraft constellation in orbits with a capacity of 120 object-control sessions over a 24-hour period.
SYSTEM STRUCTURE
- different modifications of the onboard equipment with the period of an active operation varying from 5 to 15 years and expectancy of failsafe operation of more than 0.99
- ground-based radio control stations are available in transportable and stationary configurations
- mobile checkout equipment which ensures autonomous checks of the “Komparus” on-board equipment, as well as comprehensive checks and prelaunch preparation of a satellite at the satellite manufacturer’s and at the launch site
The onboard equipment and the ground-based stations constitute a command-and-measurement system.
