Fast Positioning Method by Using Priori Data for GF-3 Satellite
摘要
Abstract
For the fast positioning requirement under various attitudes of GF-3 satellite,a fast po-sitioning method by using priori data is proposed.The method regards the GF-3 satellite position and attitude data as assistant information and then judges the visibility of navigation satellites in real time by calculating the elevations,so that the time of acquisition is decreased then the posi-tioning time is reduced.The on-orbit test verifies the effectiveness of the method by using of priori data,and the positioning time is 115s,shorter than that of other LEO satellite which is 855s.The method proposed in the paper is appropriate to various kinds of remote sensing satellite on LEO.关键词
