2009/8/20
针对GPS软件接收机提出一种跟踪部分的实现算法，该算法包括码跟踪和载波跟踪。在PC上用该算法进行模拟数据的Matlab仿真和真实数据C的实现，在集成ARCA3嵌入式微处理器的GT3000A平台上运行该程序。实验证明，该算法实现C/A码相位和载波频率的精确跟踪，并得到导航数据。
一种GPS软件接收机自适应门限快速捕获算法
2007/12/13
Abstract当前GPS接收机的搜索策略是基于C/A码相位和载波频率的串行搜索．基于二维串行搜索，本文推导了不同累加次数下捕获到信号的概率密度函数和未捕获到信号的概率密度函数，提出一种新颖的自适应门限捕获算法．该算法能根据接收卫星信号功率的不同自动地调整门限，同时保证误捕率恒定．相对于传统的固定门限的捕获算法，该算法捕获速度更快，从而减小了首次定位时间．
