GF-1 is the first satellite of China high resolution earth observation system. In order to make good use of GF-1 data for many users, this paper describes the results of area coverage, position and phase of different spectrums, and auxiliary data application, in the light of satellite orbit, observing & receiving, image geolocation, time characters and so on. Some examples of GF-1 imaging time, GPS positioning and star sensor attitude determination data interpolation are given. Based on satellite design, this paper introduces many remote sensing imaging and data processing characters for data application.
