基于GPS和GSM混合定位系统的设计与实现

本文叙述了基于GPS和GSM混合定位系统的设计和实现。介绍了基于GPS和GSM混合定位系统的系统结构及其优点。然后从移动定位终端出发，详细地介绍了定位终端的硬件设计结构，I^2C总线技术及软件结构，给出了硬件和软件的模块化设计思路。

The Combined Location System Based on GPS and GSM

This paper proposed a technology of designing a combined location system, which is based on GPS and GSM. This paper represents the architecture and advantage of the location system. And then it describes the hardware architecture of mobile location terminal, performance of signal chip that is used in this terminal, technology of I2C bus and software architecture in detail. According to these, the idea of modularization of both hardware and software is proposed.
