2. Satellite laser ranging - Wikipedia

   en.wikipedia.org/wiki/Satellite_laser_ranging

   The laser pulse can also be reflected by the surface of a satellite without a retroreflector, which is used for tracking space debris. [1] Satellite laser ranging is a proven geodetic technique with significant potential for important contributions to scientific studies of the earth/atmosphere/ocean system. It is the most accurate technique ...

3. Laser communication in space - Wikipedia

   en.wikipedia.org/wiki/Laser_communication_in_space

   Assuming available laser technology, and considering the divergence of the interferometric signals, the range for satellite-to-satellite communications has been estimated to be approximately 2,000 km (1,200 mi). [83] These estimates are applicable to an array of satellites orbiting the Earth.
