Abstract With the launch of high resolution satellites, more and more domestic satellites can be used in geological survey and have played important roles in national mineral resource exploration, mineral resource exploitation and monitoring, geohazard investigation and monitoring. Compared with domestic work, overseas geological work needs more domestic satellite data as important supporting data because of the lack of geological work and basic information there. However, the distribution of domestic satellite earth receiving stations abroad is very limited, and hence there is a great uncertainty for overseas data receiving and guarantee. Based on multiple factors analysis, this paper puts forward a weighted grade model to weigh scoring overseas geological service capabilities of domestic satellites and further analyze the overseas service capabilities of ZY1-02C satellite and other domestic satellites, thus providing important reference for conducting overseas data services analysis and overseas geological work.
