Abstract

Considering that the HALE UAV has high requirement to the autonomous navigation performance and precision during the imaging

the INS/star attitude integrated navigation system aided by the SAR is researched.Combining the disconnected output characteristic of the SAR image navigation and the asynchronous characteristic of the multi-sensor integrated navigation system

the multi-sensor integrated navigation filter model is designed which is applied to solve the discontinuous measurement modified value.The unequal interval asynchronous aggregated filter algorithm of the integrated navigation system is proposed.Simulation result indicates that the designed integrated navigation system can improve high-sky autonomous navigation performance and navigation precision during the SAR imaging

and have substantially improved the navigation precision of the HALE UAV.
