Optoelectronic Docking System

Sensors and computers control approach and coupling. Proposed optoelectronic system with no moving parts automatically controls approach of two spacecraft as they closed from distance of about 1 km to within few cm. System concept modified for use on Earth in robotic assembly, to control docking of large ships, or to guide placement of large structural components. Optoelectronic docking system automatically controls approach of active vehicle or mechanism to passive vehicle or object. Maneuvers of approaching vehicle controlled in response to optoelectronically sensed relative position of approached vehicle.
