Faster GPS signal tracking using XOR method

用两种不同的方式产生GPS信号的CA码。其中一种是将G2发生器产生的序列经过相位选择器后作为输出，然后与G1发生器异或。-Produced in two different ways of CA code GPS signal. One is through the G2 phase sequence generator as the output after the selector, and then XOR with the generator G1.

自己编写的GPS程序，包括数据重建工作，主要针对GPRMC的格式重建，程序末尾添加XOR异或程序。-I have written the GPS program, including the the data reconstruction work focused rebuild the GPRMC the format, the program added at the end of the XOR exclusive or program.

generation of gold code using two maximal length (m seq) sequences. first we need to generate two maximal length sequences and then we have to xor those , we get gold code
