ANGLES-ONLY ORBIT UPDATES FOR LOW EARTH SATELLITES

摘要

This paper provides the development of a simplified covariance model for predicting the along-track error uncertainty and error uncertainty growth rate for the single-pass, angles-only orbit update, the validation of the model using simulation and real data cases, a summary of efforts made to characterize the uncertainty of general perturbations based element sets, and conclusions on the practical expectations of the single-pass, angles-only orbit update.
