本文设计的FPGA模块需要对GPS、便携打印机和串口数据进行处理，将详细介绍如何设计FPGA和不同外设之间的数据传输。同时，在RTL编码中，编写使综合与布局布线效果更佳的代码。-In this paper, the design of FPGA modules need for GPS, portable printers, and serial data processing, will be details on how to design FPGA and data transfer between peripherals. At the same time, RTL coding, synthesis and preparation to make better placement and routing code.

需要先下载安装mapx，很容易找到，该程序是一个利用mapx和vc编写的与电子地图操作应用的程序-first need to download and install MapX, it is easy to find, that the procedure was a vc use MapX and prepared for the operation of the electronic map application procedures

GPRS部分源代码，一部分常用AT命令的代码实现，比如，打电话，发短信等-GPRS part of the source code, part of the AT command used a code, for example, make phone calls and send text messages, etc.

以前用VB，C#等很轻松将GPS信息解码。但是最近要使用C语言，（网上有一个VC的按位解的）苦于C操作字符串的难度，请各位大侠放出一份C代码解GPS。 我先贴上我用C解的代码，是直接将VB和C#的思路转过来的。 现在可以读出经度或纬度-before using VB, C#, etc. is easy to decode the GPS information. However, the recent use of C language, (the Internet by a VC-Solutions) cited a string C operation difficult, Please Shanhaiguan released a GPS Solution C code. I affixed my first solution with C code directly to C# and VB of the ideas turn. Can now read latitude and longitude

SIM868+STM32的定位代码,GPS,GPRS,并实现定位数据上传到OneNet平台，实现轨迹回放功能。

本文探讨了GPS精密单点定位的基本原理、方法和一些关键技术，给出了精密单点定位的精度！-This paper discusses the GPS Precise Point Positioning the basic principles, methods, and some of the key technologies, give the Precise Point Positioning Accuracy!

Lessons Learnt in Assisted GPS

用vc写的测试gps信号跟踪和俘获程序正确性和速度的程序-with vc written test gps signal capture and tracking procedures accuracy and speed the process

gps的开发程序，出自吉大的高手，gis开发是目前非常有前途的一个方向。-the development process, from the Kyrgyzstan big players and gis development is a very promising direction.

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
