根据卫星星历文件进行卫星坐标的解算，直接读取文件进行数据输入。-computing satellite s coordinates and input data by txt.

读取星历参数，以矩阵方式存入，进行卫星坐标解算-RINEXE Reads a RINEX NavigationMessage file andreformats the data into a matrix with 21rows and a column for each satellite.The matrix is stored in outputfile

用MATLAB编写求解伪距定位方程的程序，对实际数据进行处理，解算出接收机的位置及钟差信息。提供8个通道的两组数据如下，X, Y, Z 为WGS-84坐标系下各通道所跟踪卫星的坐标，Range为与之对应的校正后的伪距测量值。-Using MATLAB pseudorange positioning equation solver, and the actual data processing, solution and calculate the position of the receiver

卫星导航解算，通过RINEX文件提取卫星参数计算卫星坐标，然后通过伪距测量法解算出用户位置，并在GUI界面中显示。- 卫星导航解算，通过RINEX文件提取卫星参数计算卫星坐标，然后通过伪距测量法解算出用户位置，并在GUI界面中显示。 Satellite navigation solution, satellite parameters extracted by RINEX satellite coordinates, and then through the pseudo range m

在解算卫星位置时用到坐标转换，ecef坐标系转经纬度(Coordinate transformation is used to calculate the position of the satellite, and the ecef coordinate system is transferred to longitude and latitude)
