通过两个11位gold码发生器生成两个同频的GOLD序列，在通过两个吗发生器的不不同抽头相加形成新的gold序列，即所需的北斗伪码序列

The idea behind differential GPS is to remove as much errors as possible from the range measurements by establishing these errors at a reference site. In its most simple setup, a GPS receiver is located at a well surveyed position and its (pseudo) range measurements are compared with the actual calculated range from this receiver to the SV s. The differences between measured ranges and calculated ranges at the reference receiver are applied as corrections to the ranges measured by other receiver(s) close by.

在利用GPS卫星进行单点定位过程中，需要进行电离层与对流层等误差的计算以及卫星高度角的计算，卫星高度角越高受观测误差就相对较小，本程序采用高度角随机模型加权，电离层采用K8模型加以改正，希望对GPS研究的朋友有帮助。

GPS开发经典工具，很有参考价值，你可以用它在PC平台接收数据包，这样就可以研究包结构知识-GPS development of classical tools, a good reference, you can use it in the PC platform for receiving data packets, so packets can study the structure of knowledge

基带测量信号处理的算法：1.最小二乘曲线拟合法2.线性滤波方法3.非线性滤波方法非线性滤波方法就是和深组合导航系统中利用联邦卡尔曼滤波的方法是一样的，基带信号处理相当于联邦卡尔曼滤波中的局部滤波器
