Abstract
In this paper, a real-time calibration method for relative alignments between multiple heads star tracker (MHST) heads based on the invariability of inter-star angle principle is presented. Firstly, the ill effects of relative misalignments on accuracy of MHST attitude based on star-fusion are analyzed. Then, the invariability of inter-star angle principle and the changing feature of relative alignments are applied to build a kalman filtering model to estimate the errors. Finally, a simulation is used to illustrate that the method meets well the real-time requirement of accurate relative alignments of MHST.
