Preparation of local base map for lunar orbiter scene matching navigation
摘要
Abstract
To prepare a lunar local base map for the lunar orbiter scene aided navigation and landing, the preparing method and related problems for the lunar local base map were researched in this paper. Based on real data from Chang-E 2 mission, error generation and restriction ways for the local base map were analyzed combining with constraints from measurement, tracking and navigation. A set of algorithm for preparing the lunar local base map was proposed according to the global base map by Lunar Reconnaissance Orbiter Camera(LROC) in LRO mission. Experimental results show that pixel features from the generated local base map are consistent with corresponding features from Chang-E 2 orthographic projection images,the maximum coordinate location error by projection is 7. 065 1 m, and the distortion error is 6. 18 m for the observing map size in 20 kmX20 km. These results meet the precision requirement of the scene aided navigation for the lunar orbiter very well.关键词
