Spaceborne laser range finder can measure the distance to the target by injecting the pulse laser with high stability through the transmitter. The design and application of laser are involved, especially the function and performance of the laser power supply are the most important. Therefore, it is particularly important to realize the external control of the satellite laser power supply and the collection of the real-time state quantity. Based on the FPGA technology, an AC / DC power supply module, a remote control telemetry module and a display control module are designed to provide an external clock signal, a Q signal and an AD / DA control signal to the laser power supply so as to realize the laser power supply Real-time telemetry and status of the state of the LD current signal, the Q-signal real-time adjustment and control of the system, the system can set the laser re-frequency and control the laser output time, you can also show real-time laser pulse number and laser power related telemetry, The design and implementation of this system are described in detail, and the improvement of the performance and function of the remote control telemetry system with high reliability is proposed.
