“Kurs-N” radio system for mutual measurement of motion parameters for spacecraft search, rendezvous and docking
PURPOSE of the SYSTEM
The system is designed for mutual measurement of the motion parameters, that are needed to ensure automatic docking of spacecraft.
The system provides:
- mutual search and detection of cooperated spacecraft
- measuring parameters of spacecraft’s mutual motion:
- range
- radial velocity
- orientation angles
- bearing angles along two communications lines
- basic angles for definition of mutual bank angle
- angular coordinates of an “active” spacecraft in coordinates of a “passive” spacecraft
- output of the measured data into the spacecraft control system
SYSTEM STRUCTURE
- an interrogator - “Kurs-NA” - is mounted on the spacecraft performing the main rendezvous maneuvers
- a transponder - “Kurs-MKP” - is mounted on the other spacecraft or an orbital station
