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

GPS定位中应用较多的最小二乘定位，程序简单易懂，是大家学习和参考的好资料，-GPS positioning applications more least squares positioning, the program is simple and easy to understand, we study and reference information

最小二乘算法实现定位解算的MATLAB代码，并且包含GDOP、HDOP、TDOP等计算-Least-squares algorithm using MATLAB code positioning solver, and includes GDOP, HDOP, TDOP, etc.

组合导航定位中GPS与北斗组合单点定位算法，包含最小二乘与方差分量估计(The combination algorithm of GPS and Beidou in single point location)
