Abstract: Relative navigation of the non-cooperative space target is a key technology for the missions such as on-orbit servicing and close-range surveillance. Recent research shows that a weak observation exists along the range direction when the line-of-sight angle is used as the measurement information for medium range relative navigation, and double line-of-sight relative navigation is an effective solution to this problem. This paper studies an autonomous double line-of-sight measurement relative navigation method based on the formation of dual chase spacecraft. The overall architecture and detailed algorithms for the double line-of-sight measurement relative navigation method are introduced. Based on the geometric configuration among the dual chase spacecraft and the target, the propagation equation for the errors in the double line-of-sight measurement method is developed and its in-fluencing factors are analyzed. The configuration of the dual chaser formation and its influence on the performance of the method is also discussed. Numerical simulations verifies the relevant conclusions obtained.
