Optical Communication System with Range and Attitude Measurement Capability
نویسندگان
چکیده
A formation optical range and attitude sensor is being developed that uses a laser beam source and a modulated retro-reflector (MRR) target to measure distances between a few meters and a few kilometers with sub-millimeter resolution. Data extracted from multiple MRR targets on a single spacecraft will also provide arcminute-accuracy attitude information with over a ±10-deg field of view. Information encoded on the MRR allows a communication channel to be added to the ranging signal. A laboratory prototype demonstrated a ranging resolution of 0.2 mm with an absolute accuracy of ±2 mm over 2 m.
