SatComSim: a Toolkit for Analysis and Optimization of the field of view of Communications Payload in Space-Ground Communication

Abstract

For high-precision millimeter wave communication tasks, the communication field of view being occluded will seriously affect its communication quality. Accurate analysis of the field of view of the communications payload in space-ground communication, which is occluded by the solar panels and other payloads outside the satellite capsule, is the basis for optimizing the communications payload layout. In order to effectively analyze the occlusion of the communication field of view, this paper proposes a satellite communication field of view calculation simulator - SatComSim, which is based on Pro/E and STK software to obtain the basic data and calculate the occluded communication field of view through collision algorithm to provide important reference analysis results for subsequent research. Finally, we simulate the occlusion of the field of view under different layouts of payloads outside the satellite capsule and field of view ranges based on SatComSim, and optimize the communications payload layout and field of view. The simulation results show the effectiveness of SatComSim in the communications payload field of view analysis, which has an important role in optimizing the communications payload layout and improving the utilization of communication resources.
