Abstract
A remote site optical transponder device which automatically amplifies an incident laser pulse and returns it to its source is described. The device is especially useful in high precision ranging e.g. determining the motion of planets accurately and in tracking space craft. The device is powered by a long life power source and has a steerable laser light collector / transmitter system. Other essential components are a laser amplifier medium whose excitation means is triggered by part of the energy contained in an incident pulse from a laser tracking system and also a reflector.
