摘要

为提高制导火箭全球导航卫星系统(GNSS)在高动态环境中的稳定跟踪能力,提出一种使用弹上INS辅助GNSS载波跟踪环路的方法,该方法采用INS估计GNSS的多普勒频率信息,控制GNSS跟踪环路中本地信号的载波和码发生器,进而降低高动态环境对GNSS跟踪环路的影响。仿真实验结果表明,该方法不仅能有效减小跟踪环路的相位误差和多普勒频率跟踪误差,而且可提高GNSS在高动态环境中稳定跟踪能力。

Abstract

In order to improve the stable tracking performance of guided rocket GNSS in high dynamic environment, a method for using the INS of the missile aided GNSS carrier tracking loop was proposed, which INS was used to estimate the doppler frequency information of GNSS, to control the carrier and code generator of the GNSS tracking loop’s local signal and reduce the influence of high dynamic environment on GNSS tracking loop. The simulation result shows that this method can effectively reduce the tracking loop phase error and doppler frequency tracking error, and improve the stable tracking performance of GNSS in high dynamic environment.
