摘要
提出了一种北斗系统处于高动态情况下的环路跟踪设计方案,分析了FLL,PLL,DLL等环路的具体设计。实验仿真结果表明,在速度为900 m/s,加速度为10 g的高动态情况下,可以实现正常跟踪,为北斗系统在高动态下的应用提供了一种解决方法。
In this paper, a tracking loop design based on the Beidou positioning system in high dynamic environment is presented, and the design of the FLL loop, the PLL loop and the DLL loop is also analyzed. Simulation results show that in a high dynamic environment with a speed of 900m/s, and the acceleration of 10g, the proposed scheme could realize normal tracking, which provides a possible solution of the Beidou system＇s application in a high dynamic environment.
