【摘要】：基于对低空低速飞机飞行轨迹的分析,利用搭建的北斗信号实验平台模拟实现了飞行过程中对飞机位置及其速度的测算,并用以分析卫星信号接收机的定位误差。通过实验接收信号解码并解析NMEA语句,对比轨迹运动方程和实际接收的数据轨迹来分析导航精度。经验证,该方法可实际应用于对安装在飞机上的接收机进行重复性的精度测试实验分析,通过对真实环境中误差影响因素的再现,以及反复实现不同动态的轨迹来进行实验测试及精度分析,节省直接实测过程中投入的人力和设备以及时间成本。
[Abstract]:Analysis of low speed and low altitude flight path based on simulation to calculate the position and speed of the aircraft during flight by Beidou signal experimental platform, and used to analysis positioning satellite signal receiver error. By decoding the received signal and experimental analysis of NMEA statements, analysis of navigation accuracy comparison of trajectory equation and the actual data received track. After verification, the method can be applied to the analysis of the precision testing experiment was repeated on the receiver mounted on the aircraft, the factors which influence on reproduction error in real environment, and repeatedly achieve different dynamic trajectories to measuring accuracy, save direct measurement process manpower and equipment time and cost.
