Precise Orbit Determination of GPS-36 Satellite Using Satellite Laser Ranging [PDF]
Journal of Astronomy and Space Sciences, 2002 Satellite laser ranging is a technique for precisely measuring the range between a laser station and a satellite that is equipped with retro-reflectors. SLR technique was first used for Beacon-B satellite in 1964 with the ranging accuracy of meter level.

Laser back scatter: Limitation to higher repetition rate [kHz] Satellite Laser Ranging system
Geodesy and Geodynamics, 2021 Satellite laser ranging (SLR) with higher repetition rate is the recent trend for its various advantages. Laser backscatter (coincidence between recently transmitted pulses and received pulses near the detector) is found to be a constraint for the ...
