摘要 利用交互式多模型的带宽自适应调整特性实现了高动态与静态环境下通用的GPS信号载波跟踪算法。仿真结果表明,该算法在保证满足高动态GPS信号载波跟踪要求的前提下,降低了静态时的频率跟踪误差,避免了不同动态环境下多个载波跟踪算法及切换方案的设计。 A unique GPS signal carrier tracking algorithm used in high dynamic and static environments was proposed. The algorithm was developed based on the nature of adaptive bandwidth adjusting of lMM, Simulation results show that the new scheme reduces the RMS frequency error in static environment, while the requirements for carrier tracking in high dynamic are achieved. Multiple algorithms for different environments and their exchange schemes are avoided.
