| 摘 要： | 在INS/GPS组合导航系统中，当使用环境对GPS信号捕获的快速性有特殊要求时，运用外部信息辅助可以有效提高GPS信号的捕获速度。虽然GPS捕获算法在理论上已经比较成熟，但是在具体的工程实现中却存在诸多问题。本文针对实际应用需求，分析并建立了基于INS辅助的GPS快速捕获仿真模型，设计了相应的半实物仿真系统，并对该系统进行了多次动态仿真试验。对试验结果的分析表明，本文所采用的GPS捕获方法在实际的硬件环境中仍然有效，GPS在INS的辅助下不损失精度，而捕获速度可以提高两个数量级，满足实际系统需要。

| Abstract: | In INS/GPS integrated navigation system,if there are special requirements for the acquisition speed of GPS signals in application environment,then the speed can be dramatically improved with the aid of external information.There are still problems in the engineering implementation process although the algorithm of GPS acquisition is mature in theory.In the light of the application requirements,fast acquisition of INS-aided GPS is analyzed and set,a corresponding hardware in the loop simulation system is des... |
