程序1主要使用矩阵模拟GPS 24卫星的位置，并计算出多颗卫星的伪距和时差差分方程。 方案2主要模拟GPS卫星，包括卫星轨道，运动卫星。 程序3通过计算近点角度，近点角度和接近角度角度来模拟卫星的定位。-Program 1 mainly uses the matrix to simulate the position of GPS 24 satellite, and calculate the pseudorange and clock difference equations of multi

通过对卫星的数据来进行网络编程，利用相关的插值算法实现相关的功能。(The network programming is carried out by the data of the satellite, and the related functions are realized by the relevant interpolation algorithm.)

模拟一条路线，用GPS卫星导航，得到计算轨道，最后得出误差(To simulate a route, navigate with the GPS satellite, get the calculation track, and finally get the error.)
