Closed Loop Pointing System for Ground to Satellite Communications

原文（中文）

A method for measuring turbulence is provided. Laser beams encoding information is received from terrestrial locations at a set of satellite communications systems. A satellite communications systems in the set of satellite communications systems comprises a satellite and a relay system that is configured to receive a laser beam encoding information from a terrestrial location and relay the information to the satellite, wherein the relay system is positioned at a selected distance from the satellite and the selected distance is based on a speed of the satellite. Attributes for the laser beams encoding the information received by the set of the satellite communications systems from terrestrial locations are determined. The attributes are compared to an expected attribute without turbulence to form comparisons are compared. Relative turbulence levels based on the comparisons of the attributes to the expected attribute are determined.
