包含三个M文件，其中ReadGpsData.m是读取导航文件，TimetoJD.m是将民用年历转换为儒略日，CalPos.m是将读取的数据计算卫星的坐标。 此程序计算结果较好。 (M consists of three documents, which is read ReadGpsData.m document navigation, TimetoJD.m is converted to civilian Julian calendar date, CalPos.m is to read the coordinates of the satellite data. Calculation of this procedure with satisfactory results.)
