The satellite laser retro-reflector is used as part of the space load of the SLR system and is mounted on the satellite surface.Its function is to directionally reflect of the laser signal and realize the precise ranging.Navigation satellite laser reflector is a main branch of spaceborne laser reflector applications.The development status of the navigation satellite laser reflector technology at home and abroad is briefly reviewed,its opto-mechanical design is discussed,and future trends and research directions are prospected.This is also useful for the design of other types of laser retro-reflector.
