Abstract
The ultraviolet(UV) sensor-based autonomous navigation for spacecrafts is studied.In order to guarantee accuracy and reliability of the UV satellite navigation system
the navigation system is requested to have the fault detection function and adaptive capacity.The strong tracking filter in the navigation system is used.Simulation results demonstrate that this method can obtain high orbit accuracy.When the system is failure
the filter can track abrupt state changes and gradual changes.It can greatly improve UV satellite navigation system’s navigation accuracy and working reliability.
