这是GPS接收机仿真的程序， GPS数据由给定文件来模拟，对于GPS爱好者很实用。-This is the GPS receiver simulation procedures, GPS data given by the paper to simulate, for GPS enthusiasts practical.

GPS中NEMA协议的校验值的计算，一字节模和计算工具。用于校验和计算。

目前GPS（全球定位系统）定位应用市场日趋成熟，正在进入应用的高速发展时期。本文以一款EverMore公司的GM-X205GPS接受模块为例，介绍了其数据格式，以及应用PIC16F874单片机RS232串口进行数据接收的程序-current GPS (Global Positioning System) location-based applications market becomes more mature, Applications are entering a period of rapid development. A EverMore paper to the GM-X205GPS accept modules for example, introduced a data format, and the application of PIC16F874 RS232 serial port for data receiving program

android gps jni源码函数调用了hw_get_module加载硬件适配模块.so文件，接着通过hw_device_t接口调用open()函数，实际执行了gps/loc_api/libloc_api/gps.c定义的open_gps函数，然后调用gps_device_t接口的get_gps_interface函数，此函数也是在gps.c中定义的，最后返回HAL层中loc_eng.cpp文件的sLocEngInterface，从而打通了上层到底层的通道。
