Research and Analysis for Relay Communication System of Chang'e-4 Lunar Relay Satellite

In order to realize the landing mission of Chang'e-4 satellite on the far-side of the Moon,a lunar relay communication satellite is developed to provide relay communication service between the ground station and the lander as well as the rover of Chang'e-4 on the farside of the Moon. The relay communication system is the main payload and the key to accomplish mission objectives of the relay satellite.The technical scheme of the relay communication system is studied and analyzed in this paper.
