我在美国公司用的CA code GPS toolbox,this is matlab toolbox I write and use in my company for simulating a CA code in GPS

GNSS_SDR是一套不可多得的matlab代码。它给出了接收机每一部分的子函数，编程效率高，可读性强。此外，A soft-defined GPS and Galileo Receiver系统的介绍了整个接收机的原理，并针对程序给出说明，通俗易懂。-GNSS_SDR is a set of matlab code for GPS&Galileo Receiver.Every part of the receiver is presented as a function,so it is easy

提出了一种混合GPS/TDOA 的泰勒级数-最小二乘算法，在GPS 和TDOA 定位方法都无法独立 定位时实现了定位-Proposed a hybrid GPS/TDOA Taylor series- least squares algorithm, GPS and TDOA positioning methods are unable to locate an independent positioning

附件是《软件定义的GPS和伽利略接收机》一书的matlab代码，开发者可以学习、利用、优化和提升，详细它会给你带来很多灵感。(The appendix is the matlab code of the book "software defined GPS and Galileo Receiver". Developers can learn, use, optimize and upgrade, and it will give you a lot of inspirati
