Design of Positioning and Sensing Network System Based on Beidou

This paper presents a position and time information sensing network system. It uses Beidou satellite navigation system as the sensor of position information and precise time information, and takes advantage of the local area networks and Internet to build the platform of transmission. The hardware platform of system is based on ARM7 microprocessor LPC2378. It includes a highly integrated embedded sensor terminal hardware and software system, and also contains a software system of information delivery platform. The system can make use of the position and time information of Beidou satellite navigation system to achieve real-time positioning, local transfer and remote transmission. It can also realize visualized monitoring of the dynamic information of positioning and the status of satellites in the remote center. The system provides a kind of practical and high-performance solution for the application of Beidou satellite navigation system. It has some practical value for the promotion of industrial development of Beidou satellite navigation system.
