To meet the application requirement of real-time acquisition of observed solar data from “Kuafu A” satellite, the model, which describes the spatial relationship of position between “Kuafu A” and a single fixed station on the ground, is proposed. Then, some quantitative assessments of receiving efficiency of available domestic and oversea stations are also made. Moreover, some basic principles are illustrated for global layout for ground stations as well as a feasible optimal scheme. The results are considered as important references for real application of data communication system between spacecraft and ground of “Kuafu” project.
