The ability of data transmission and processing is an important factor in the construction of the moon-based platform. How to transmit the observation data to the earth station efficiently and accurately is a critical step to carry out the further researches. Through the joint simulation of STK and MATLAB, we simulate data transmission link from Moon-based platform to Earth and put forward a downlink communication scheme for the platform. It has been proved that the scheme of two relay satellites with 40 degrees apart and of utilizing the middle latitude earth station can receive reliable information all the time. It could make the downlink receiver get information with enough power and low bit error rate, so as to ensure the operation of the moon-based earth observation platform.
