Docking/Berthing Sensor Using A Laser Diode Rangefinder, CCD And Video Tracker

A docking/berthing sensor can support operations for NSTS orbiter retrieval of satellites or free-flyers, space station rendezvous with OMV and NSTS orbiter, and orbiter/lander docking for interplanetary missions. A laser docking sensor (LDS) has the capability to fulfill these missions due to its ability to optically resolve the target for measurement of target attitude in conjunction with the inherent compactness, low power consumption and high reliability of all-semiconductor optoelectronics. An LDS design is presented using a laser diode rangefinder, CCD array with active laser diode illumination, and multi-target video tracker.
