An Angles-Only Navigation and Control Scheme for Noncooperative Rendezvous Operations

摘要: The use of vision sensors for noncooperative rendezvous operations is attractive, especially microspacecraft, because are usually small size, light weight, and low cost but provide rich information. However, vision-based extremely challenging. It difficult to accurately measure the relative distance between a chaser spacecraft target. In this paper, we propose systematic angles-only navigation control scheme operations. hybrid framework that combines offline trajectory planning integrates observability condition online tracking based on nonlinear model predictive control. A filter used in estimate motion by using only angle measurements. scheme, can closely track desired simultaneously guarantee estimation accuracy filter. This paper provides general practical effectiveness verified extensive simulations.
