▍1. GPS_SPP
GPS伪距单点定位,包括导航文件、观测文件、精密钟差和精密星历的读取,对流层Hopfield模型,电离层K8模型,采用最小二乘法,最后通过调用matlab来计算测站坐标。对GPS编程初学者是很好的编程哦。(GPS pseudorange point positioning, including navigation documents, observation files, precision clock bias and precision ephemeris read, Hopfield model troposphere, ionosphere K8 model, using least square method, and finally by calling matlab to calculate station coordinates. The GPS program is a good program for beginners oh.)
