Description

technical field

[0001] The invention relates to a test system, in particular to a test system suitable for remote sensing satellite laser satellite-ground communication links, which belongs to the field of satellite system level comprehensive test. Background technique

[0002] The space-borne laser communication system uses laser as the carrier of data transmission to complete the tasks of capture and tracking with the laser ground station and two-way data transmission between the satellite and the ground to meet the user's demand for high-quality, large-capacity, and high-bit-rate data communication transmission. Laser communication requires large-capacity Information is transmitted in real time, featuring high reliability and high confidentiality. According to the orbit of the satellite, the ground comprehensive test simulates the satellite-ground capture and tracking process according to the flight program. The specific process is as follows: the satellite-borne laser co...
