摘要

This paper discusses the implementation of a Stellar Positioning System as well as techniques for error mitigation in experimentation and data post-processing. The hardware used during the development and testing of the Stellar Positioning System is described. Star-centroiding, star-identification, attitude estimation, and the local gravity vector were used by the Stellar Positioning System to determine latitude and longitude. Image processing, attitude filtering, and focal length estimation are presented as techniques to further improve the capabilities of the system. The resulting prototype was tested in three different locations and the results demonstrate accuracy of the Stellar Positioning System to be within 50 meters for short time intervals.
