Abstract
In order to improve the integrated navigation performance of the civil plane and ensure the safety of the RNP operation,an onboard integrated navigation system and performance evaluation method based on DR/GPS/VOR/DME is proposed.Considering multi-sensor error,the system error model is established.The measurement model of system is designed based on residual error x2 detection method.The square-root filter based on sequential processing is used to implement position optimization estimation.Simulation result indicates that the integrated navigation can estimate the position accurately.The ANP algorithm can estimate the real-time error characteristics of integrated navigation system during the 95％ time and have high assessment precision,which can satisfy the requirement of RNP.关键词
