【摘要】 详细介绍了BASS(同步信号块处理)方法在静态软件GPS接收机数据处理方面的应用。首先说明了BASS的基本思想,然后具体介绍了捕获时根据相位差求精频的方法,以及在跟踪时使用理想相关方法进行码跟踪,使用相位差方法频率跟踪的详细过程。最后,在一个C/A码周期内数字化C/A码非整数的采样率下,提出了首尾相接的BASS改进方法,成功实现了软件GPS数据的跟踪。更多还原

【Abstract】 A method BASS(Block Adjustment of Synchronizing Signal) for GPS signal processing is presented, that can be used in a static software GPS receiver. Firstly, the basic principle is introduced, then signal acquisition to get fine frequency , code tracking and carrier frequency tracking using BASS method is addressed in detail. At last, when the number of digital C/A code is non-integer during one C/A code period, end-to-end BASS method which is an improved BASS method can achieve the GPS signal tracking.更多还原
