Performance analysis and concept description of laser diode optical radar systems for precision tracking and ranging between spaceborne targets are presented. Intersatellite ranging for determining gravity disturbances on satellite orbits and range measurement for spacecraft rendezvous and docking maneuvers support are considered. Both tasks can be performed, according to theoretical studies, using diode laser systems. A ground based continuous wave (CW) laser diode ranging system was successfully tested as a first step towards creating a functional model of a spaceborne unit. For the intersatellite mission, a combination of pulsed and CW systems is proposed, that is a pulsed laser for rapid scanning and coarse ranging and a CW laser for precision ranging. Both systems are suitable for rendezvous or docking maneuvers.
