Abstract

Relative navigation for satellite formation flying is very important to complete its flight mission?and the vision-based relative navigation is especially an useful method. In the paper, much attention is paid on the research of getting the accurate relative information of position and attitude with single image.
The algorithm of relative position and attitude determination for cooperated spacecraft is obtained with single image. The non-linear problem is transformed into the optimization problems in process; the objective function in view of this question is constructed, and this optimized problem has been solved by using the method of Plans Newton. As the method of Plans Newton is a faith territory method, it has certain application superiority that it can realize the algorithm overall astringency and saves the computing time.
Meanwhile, the application of vision-based relative navigation in satellites formation flying is studied. Based upon analyzing the relative motion dynamics model of the closing satellites, the relative motion model that using relative orbit elements is presented. The expression of solution of the C-W equation and influence certain parameters regarding flight pattern design are analyzed, but also the parameters of the trajectory of encirclement satellites to obtain the method is inferred, and it is shown in the figures. When using vision-based navigation, the EKF is introduced and carried on to obtain the real-time information of relative position and velocity between the satellites. The simulation result indicated that the astringency of the algorithm is well, the precision is high, and it can satisfy the demand of most space mission.
