ARM9 GPS Positioning System Based On Embedded System

In recent years, along with the rapid development of nationa l economy, China's autoindustry come into a high-speed stage, That motorists can have a gps equipmentrequirements will become increasingly urgent. GPS gradua lly came into people's lives, givedrivers brought great convenience, GPS positioning system market is rapid ly developing.Based on this dema nd background, this paper studies the GPS positioning system. Thissystem with GPS positioning technology analyzed its accuracy, real-time, and stability.This paper ma inly studies the following contents:1, For embedded systems, vehicle-mounted navigation system of the developingsituation of domestic and foreign were studied, Overview of the embedded system concept,structure and its characteristic, and according to the embedded system structure characteristicsand design principles, outline design idea, for the embedded GPS positioning system designgroundwork.2, According to the embedded vehicle-mounted navigation system, and raises thefunctiona l requirement of the overa ll design scheme of the system, and gives the specificsoftware and hardware part of the composition. In this paper using target platform S3C2410 ison ARM920T processor kernel development companies using one of the embedded processors,wireless communication module select of GSM/GPRS wireless module, double-frequencymodule MC35i by Siemens company T15 GERMIN GPS receiver realized received theinformation of GPS;3, This paper introduces the embedded navigation systems software developmentplatform - embedded operating system under development tools simultaneously ADT detailedintroduced embedded development environment and debugging. For applica tion developmentto la y the foundation.4, This paper introduces the navigation system applica tion development, gives thelocated functiona l function, it shows that the output functions such as concrete programsection and experimental results.
