摘　　要：提出一种利奇格网模型平均方法的导航接收机可靠性处理方法。该方法从可靠性处理的原理入手修改传统可靠性处理优化的约束项,消除了不同时延信号对合成信号的影响,从而保证可靠性处理过程中有效抑制干扰,并且不影响导航信号的捕获和解码。理论分析和仿真结果表明,该方法能有效解决可靠性处理中的卫星导航信号失真问题。Reliability processing method of satellite navigation receiver based on LEACH grid model was put forward.This method modifies the constraints of traditional reliability processing optimization from the principle of reliability processing,eliminating the influence of different delay signals on synthetic signals,so as to ensure that interference is effectively suppressed in reliability processing without affecting the acquisition and decoding of navigation signals.It can effectively solve the problem of satellite navigation signal distortion in reliability processing.
