GPS模块开发：vb、rs232串行通信控制

资源描述该代码主要实现的是对一个网形进行平差计算，所采用的语言为Csharp，本代码可以作为初学C#进行练手，也可以通过本程序了解GPS网平差处理的基本过程，希望对GPS研究者有所帮助。

GPS解算算法，解算星例，求解位置，转换位置，估算大气延迟，修正本地时钟等；

上一个的继续,连续有九个压缩文件,大家可以打开解压后自己慢慢享用,这个都是本人调试通过了的,希望共同进步!-A continuation of a row has nine compressed file, everyone can open their own after extracting slowly to enjoy, this is my debug adopted, and I hope common progress!

GPS开发经典工具，很有参考价值，你可以用它在PC平台接收数据包，这样就可以研究包结构知识-GPS development of classical tools, a good reference, you can use it in the PC platform for receiving data packets, so packets can study the structure of knowledge

MO中利用图片生成点符号专题　 deskfee 发表于 2005-3-15 14:34:24 用truetype字体可以比较方便的实现点符号，但用图片可以实现更加漂亮的点符号（如果你认为你做的图标足够漂亮的话，^_^），只是实现起来麻烦一点。 文件是txt,下载完后请先更改-MO use photographs to generate symbols deskfee topic published in 2005-3-15 14:34:24 truetype fonts can be used to facilitate the realization of more symbolic point, but pictures can be used to achieve a more beautiful symbol of the point (if you think you have done enough beautiful icon, ^ _ ^), but is only one point up trouble.
