摘　　要：以GRACE重力卫星激光反射器为例,理论分析了卫星激光反射器的激光入射角、速差补偿和相对有效反射面积,并对激光反射器进行了可测性分析和测距误差分析。通过TROS1000流动卫星激光测距(SLR)系统对GRACE卫星激光反射器进行测距实验,测距精度为0.9cm,实验结果与理论分析结果基本一致。Taking the laser retro-reflector on GRACE gravity satellite as an example, the main technical parameters, such as the laser incident angle of laser retro-reflector on satellite, velocity aberration compensation, and the relatively effective reflection area, are analyzed theoretically, and the testability and ranging error analyses for a laser retro-reflector on satellite are conducted as well. By using the TROS1000 mobile satellite laser ranging （SLR） system, a ranging experiment on the laser retro-reflector on GRACE satellite with a precision of 0.9 cm is conducted and the experimental result is basically consistent with the theoretical analysis result.
