| 摘 要： | 高动态的接收机指在接收信号的载波附有较高的随时间变化的多普勒频移时仍能正常工作的接收机。GPS接收机主要通过载波叉积自动频率跟踪技术以及载波辅助技术等方法来应对高多普勒频移。本次重点研究了高动态GPS接收机扩频接收核心技术中与载波叉积自动频率跟踪技术相匹配的GOLD码跟踪技术，在此基础上建立了仿真的系统模型，并根据此模型应用Matlab simulink进行了具体的实现。

| Abstract: | High-dynamic GPS receiver is the receiver that can work properly when the carrier has high Doppler frequency shift which changes with the time. CPAFC cartier frequency tracking algorithms were often used to deal with high Doppler frequency. The code-track algorithms were researched which could work with the CPAFC carrier frequency tracking algorithms, and the system model was set up and it was simulated by Matlab simulink to give the result. |
