Design of satellite navigation information transmission system based on DSP and Ethernet chip W5100

A kind of satellite navigation transmission system based on DSP and Ethernet hardwired TCP/IP stack chip W5100 is designed to satisfy the long distance and abundant data transmission required in satellite navigation signal processing. The system is made up of central processor and a number of data processing units. Each processing unit collects and processes satellite navigation information under the control of DSP, and sends the information to central processor with the flexible and fast transmission ability of W5100. The system is simple and efficient, and the transmission speed of every processing unit can reach 3Mbytes/s, which satisfies the system design require. The system has been put in practical application.
