此源程序是基于HID的gps程序，用WINDOWS自带的HID驱动，产生的xml文件与GOOGLE地图文件类似，可以实现GPS模拟定位。-this source code is about gps based on HID Driver,which is included by windows.

使用STM32(cortex-M3核)模拟GPS模块（摩托罗拉产品GT-UT ONCORE）与基站设备交换机通过双串口进行AT指令交互完成授时(cpu之systick产生1pps信号)，测试成功。-Use STM32 (cortex-M3 core) simulated GPS module (Motorola products GT-UT ONCORE) and base station equipment switches through dual serial AT commands in

车载定位系统的设计与模拟实现,关于GPS的一片好文章-Design and simulation of vehicle positioning system implementations, a good article on the GPS

proteus的arduino开发元件库，含有arduino模块，gps模块，gsm模块，能够很好模拟arduino开发(this is a library for proteus ,you can simulate arduino use this)
