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.
