Abstract: During the mission unmanned aircraft autonomy for navigation and CD4072BF3A datasheet and precision of high demand, the paper design based on synthetic aperture radar (SAR) supporting the INS / Star attitude combination of navigation and CD4072BF3A price and positioning system, and CD4072BF3A suppliers and navigation for the SAR image and the output of non-continuous multi-sensor integrated navigation system measures the output of the asynchronous nature of the establishment of a revised measure to solve intermittent combination of multi-sensor navigation Kalman filter model asynchronous focus for kind of navigation or positioning problems have some significance. 0 Introduction unmanned aircraft and manned aircraft, it has small size, low cost, easy to use, low requirements of the operational environment, the battlefield survival ability...
