User's Unit Of RTK-GPS System Based On Internet Studying And Designing

GPS (Global Positioning System ) is a kind of high-accuracy navigation system. With the development and perfection of GPS technology, GPS is widely used in each field. While GPS orients, based on Internet difference divide into navigation system have high accuracy , real-time character characteristic. So, setting up such a system has very important realistic meanings.SZCORS system whether such a difference based on Internet divide into GPS navigation system, this system can offer RTK service through the network in the relatively vast range. So long as having Internet place of network, user can have to go to difference assign and revise serving through Internet enhancement network (IBAN ) of network. This method of data transmission through Internet can accelerate data exchanged among man-machine and realize that the data carry on data transmission while gathering on the spot, accelerate parameter of coordinates to ask and solve.The subject named by " user's unit of RTK-GPS system based on Internet studying and designing ", stem from the application development item of the unit of user of SZCORS system. Design one suitable RTK measuring system flows and stands when it is real in SZCORS system. Studying according to SZCORS service characteristic and domestic and international GPS real-time RTK measuring system of mainstream of system, under analysing guidance in the demand, in case of meeting design considerations and technical indicator, I have designed overallly. Under the guidance of ones that design overallly, I have carried on the detailed design of the systematic hardware. Data chain linked up datum stand and flow stand is the only route. The communication way in which flow stand reach the datum stands is transmited swift , reliable , cheap expenses to choose, network cover wide, which is our design object. According to Shenzhen characteristic that area use, through comparative analysis, draw GSM datum business satisfied with the above demand. Then, suitable for the field to survey and draw to one set that works out, the running environment adopts some key module of the software of Windows CE to prove for PDA, operating system. Namely provide GPS data received and GPS data coordinate exchanged 's the basic train of thought and key algorithm .Through successful research and develop by SZCORS system's flow stood , I believe that can provide some reference for this kind of system developer , help developer choose the most suitable train of thought of development according to one's own terms.
