Among all different technologies, Internet, computer and communication are the most significant part to promote personal information exchange in speed, range and capacity. This dissertation tries to build a versatile platform for applications to mobile individuals for surveillance and control by adopting and integrating modern mature technologies. 　　In the proposed real time surveillance and control system architecture, there is an urgent demand of TCP/IP capability to connect client data into server integration through mobile communication system. Under such demand, an embedded system is designed and implemented using ARM CPU to process mobile data, transmit via communication device, collect and display mobile data by an Internet server, and offer a full function of surveillance capability to mobile users. 　　System design, implementation and verification are carried out in this dissertation with detail descriptions of the functions and performance to accomplish the system operation. Experiments on vehicle motion, ultralight flight, airport surface detection, and several other functions are verified in real time monitor on geographic information system (GIS). Experiment statistics data are demonstrated and discussed with different scenarios. 　　As for the global positioning system (GPS) being a mature technology for positioning, GPS is adopted to report client position in real time in this study. However, while GPS is suitable for real time positioning, its defect of inaccuracy can be improved by a differential correction. Using the proposed client hardware, a differential GPS (DGPS) technology can easily be established. This dissertation proposes a three reference stations installation for island-wide DGPS applications. It is proven to correct GPS error within 5 meters. 　　This dissertation verifies the proposed system design being feasible and valuable for data exchange configuration using GSM in PPP and GPRS in TCP/IP both in hardware and software. Under full development, the proposed real time surveillance and control technology using mobile communication above the ground up to 1000 feet low altitude can be viable and valuable for practical applications.
