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。
Based on the aircraft flight path,the simulation experiment platform of the BDS can be used to simulate the process of the flight and calculate the position and velocity of the aircraft. Afterwards,the flight of the general aviation from Guanghan to Suining and the flight trajectory signal through the BDS experiment platform were analyzed. The NMEA statement were received and the position data can be extracted to analyze the navigation accuracy. This method can actually be applied to test the accuracy of the receiver installed on the aircraft and save manpower and equipment during the measurement process as well as time cost.
