Research On Response Performance Test Of Airborne Beidou Receiver's Maneuver Flight Function

With the rapid development of navigation technology,the application of global navigation satellite system(GNSS)is more and more extensive in the field of civil aviation.If Beidou satellite navigation system(BDS)is going to be applied in the field of civil aviation,the airborne receivers of BDS must meet requirements about airborne navigation equipment specified in documents promulgated by radio technical commission for aeronautics(RTCA)and technical standards orders(TSO),such as positioning accuracy,velocity measurement accuracy,timing accuracy,and receiver autonomous integrity monitoring(RAIM),and also requirements of response performance of maneuver flight function.Based on the performance standards of global position system(GPS)airborne navigation equipment,the research mainly focuses on the response performance test of maneuver flight function.Taking GPS as an example and according to RTCA/DO-208,firstly the article introduces the response performance test items and standards of BDS airborne receiver's maneuver flight function,including prediction of maneuver flight,position display,track deviation display,waypoint distance display,and so on.And flight trajectories needed in maneuver flight are also introduced.Then,the algorithms used for generate the flight trajectory that the response performance test of BDS airborne receiver's maneuver flight function needs are discussed deeply,by using the transformation of simulation time step and the update of coordinate system.The algorithms include the algorithm used for generate the horizontal flight trajectory composed by flight legs and transitions between legs,and the algorithm used for generate the vertical flight trajectory designed by analytic method and regardless of the aerodynamic model.And taking a standard instrument departure(SID)of Beijing Capital International Airport as an example,the algorithms for flight trajectory generation are verified.Finally,the navigation database and the man-machine interface are designed using SQL Server and C#.NET.And the scheme of performance test is designed.Simulation of a complete flight trajectory generation and the respond performance test of airborne BDS receiver's maneuver flight function is conducted.The flight state parameters and the results ofresponse performance test during simulation are provided.Results of simulation show the research of can effectively verify the response performance test of BDS airborne receiver's maneuver flight function.
