Test-flying is a effective method to evaluate sensors′performance.A method based on data fusion for multi-sensor′s accuracy evaluation is proposed,which overcomes the shortcoming of using a single sensor as the evaluation criterion.The evaluation system designed in this paper contains the algorithms of Kalman filter,RTS fixed-interval smoothing,weighted least-square.Based on the analysis of these data fusion algorithms,this paper develops a multi-sensors' accuracy evaluation system.The design and implementation of main function modules is proposed.At last,this paper tests the evaluation system with a group simulation data.The test results shown that this system can evaluate the navigation sensors performance correctly.
