A location algorithm based on Stiefel manifold particle filtering

To improve precision of positioning process of spacecraft, with full consideration of light conditions, a kind of spacecraft positioning algorithm for particle filter based on Stiefel manifold was proposed. Firstly, wireless signal tracking model of spacecraft positioning was provided and observation model for moving object positioning was built based on path loss model; secondly, the concept of invariant measure was introduced and particle filter of Stiefel manifold was built to realize improvement of algorithm performance. In addition, it was applied to research on spacecraft positioning; finally, the effectiveness of the proposed model was verified through simulation experiment.
