Patent ID: 8081302

Claim:
An optical sensor for measuring relative position, velocity, attitude and attitude rate of a satellite comprising: a laser capable of emitting coherent electromagnetic radiation; a coherent detector for measuring coherent radiation; an energy detector for measuring coherent and non-coherent radiation; a telescope having a primary and a secondary mirror; a first beamsplitter situated to direct a first portion of said emitted coherent electromagnetic toward said coherent detector and to direct a second portion of said emitted coherent electromagnetic radiation toward said secondary mirror of said telescope; and a second beamsplitter situated to direct a first portion of light collected by said primary mirror of said telescope and relayed via said secondary mirror to said beamsplitter to said coherent detector and a second portion of said collected light to said energy detector, wherein the optical sensor, having the coherent detector and the energy detector, measures relative position, velocity, attitude and attitude rate of the satellite.
