采用C#窗体应用程序编写的单点定位代码

基于JT/T808 协议及数据格式的GPS终端模拟程序，符合交通部的例子，可以参考

GPS相关工具，包括Angle Conversions，Coordinate Transformations，Date Conversions等程序组-GPS-related tools, including Angle Conversions, Coordinate Transformations, Date Conversions procedures Group, etc.

对于WAAS系统的最终衡量标准是可用性强调了导航系统的运行经济性。它被计算为时间的WAAS系统提供位置固定的准确性，完整性和连续性的指定级别的分数。最低运行性能标准（MOPS）的WAAS指定必须在99.99999％的概率得到满足的差分改正导航解决方案的垂直防护等级（VPL）和水平防护等级（HPL）的计算。因此，真正的误差不能超过保护水平不止一次107秒钟。如果计算出的保护水平超过了相应的警报上限则报警被丢弃的操作无法继续进行。如果操作已经开始这个条件是连续性违反和复飞，必须进行。否则系统被声明为划时代不可用。
