Design And Implementation Of Beidou Satellite Positioning Terminal Based On S3C2410

The Beidou satellite navigation system established autonomously in China is independent of other global satellite navigation system.It can provide users with high precision,high reliable positioning,navigation and timing services.The construction of the Beidou satellite navigation system with intellectual property has very special significance in our national security and many other aspects.The topic research in the thesis is to develop a target position monitoring system based on embedded processor and GPRS communication way.The system can collect the target data from satellite and send them to a data bases on cloud server to realize the positioning function combined the technology of the Baidu map API.This paper is to study the front circuits' design of position data acquisition,processing and transmission for the purpose of data processing and positioning on cloud server.The design of the Beidou satellite positioning terminal consists of data receiving module,wireless transmission module,positioning data display module and data processing and control module based on ARM 9 processor S3C2410.Firstly,the Beidou satellite module receives the target location data and send them to S3C2410 processor via a serial port for data packing and processing.Secondly,the location data processed will be displayed on the local LCD screen and transmitted to the upper computer through GPRS module.The control module is designed to be a minimum system according to tailorable characteristics of the embedded software and hardware.Linux kernel,U-boot software transportation and root file system are also analyzed briefly in the thesis.Through practical test the system basically achieved the expected functions.The positioning terminal designed and location application software on the cloud server together make up the Beidou satellite target positioning system with feature of higher positioning accuracy.After perfecting this system will have great practical significance in the location fields.
