Network Transmission And Data Processing Of GPS Positioning Data Using RCM2200

With the rapid development of micro-electronic technology and Internet,miniaturization and network realization will be a developmental direction of DGPS. It can meet many user requirements such as device cost and algorithm agility and so on. How to obtain and process GPS data efficiently is an important technology.The RabbitCore RCM2200 microprocessor module features an integrated Ethernet port and provides for network communication systems to be built easily. This paper presents a new scheme based on RCM2200 and GPS receiver with the aim to solve DGPS location problem through network. The author first completed interface design between RCM2200 and GPS25LP-OEM,and connected RCM2200 with local area network. Then a communication controller was developed on RCM2200 microprocessor module using Dynamic C language to program,which could realize receiving GPS data and transmitting these data to local area network in the form of UDP message. In local computers,the author used Visual C++ to program and presented real-time data that was useful for location to users. The result was shown that the adopted scheme was reasonable and the presented data was reliable.
