| 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 uneq... |
