超宽带定位系统中重要的参数，GDOP因子，本方法采用三站TDOA定位方法-UWB location system important parameter, GDOP factor, this method TDOA location method using three points

代码实现了超宽带基本定位算法，包括TOA,TDOA,以及TOA三维定位，所有代码已经在matlab 7.1下调试通过-The code is about basic positioning alogrithm of UWB,including TOA,TDOA and the 3d positioning of TOA,all of them is debuged successfully on matlab 7.10.

TDOA算法，用于解决uwb中的matlab仿真定位问题。(TDOA algorithm is used to solve the MATLAB simulation positioning problem in uwb.)
