gps导航工具包，可用于分析GPS误差，伪距及导航融合算法-This report include the review of • Principle of Radio Navigation: navigation base on trilateration has been investigated and the over determined Eq. for navigation has been solved. • GPS Ephemeris Data

gps位置速度及错误计算的说明文档。可以计算位置。-gps position, velocity and error calculation documentation. Location can be calculated.

利用Matlab进行卫星伪距定位，根据测量方式的不同，GPS定位的方法也不同，假令在无误差的情况下进行定位，即可利用Matlab将定位问题转化为非线性方程组问题。-Matlab, satellite pseudo-range position, according to the different measurement methods, GPS positioning methods are different, Jialing no error in the case of position
