通过本程序，实现通过串口接受GPS接收机信号，并显示纬度、经度、航速等信息-through the procedures, accepted by serial GPS receiver signal, and display latitude, longitude, speed and other information

GPS串口通信程序，新建了一个数据库ACCESS，在显示当前GPS信息的同时可以存储以前记录过的信息，保存在数据库中，便于以后查阅。当前GPS信息包括：时间，经度，纬度，速度，真实航向以及磁偏移-GPS serial port communication program, a database of new ACCESS, show the current GPS information can be stored at the same time the information previou

实现在以gps为起点的情况下，组合导航实现航位推算，计算物体的速度和角速度，从而得出物体的距离和航向。-Gps as a starting point in order to achieve the case, dead reckoning navigation to achieve calculation speed and angular velocity of the object to draw the object distance and course.
