【摘要】：对于要执行特殊任务的目标，指挥人员要知道其在监控范围内的准确位置，就需要对其进行连续地跟踪定位。例如，陆军特战队员在战斗中的具体位置，公安消防人员在出警时的具体路线、具体位置，还有120救护中心的车辆如何寻求最佳救护路线，这些问题都是运动目标跟踪定位系统所要解决的。随着国内移动通信技术，Internet技术和差分GPS技术的飞速发展，在民用和军用领域，，技术人员都在寻找合适的运动目标跟踪定位技术。为了解决上述问题，设计了一种差分GPS运动目标跟踪定位系统。这个系统充分利用了GPS、GPRS、Internet的技术优势，设计完成的系统能够对运动目标进行准确的跟踪定位，让网络服务器能够及时对目标的状态做出正确的判断。差分GPS目标跟踪定位系统主要由服务器、基站和移动站三部分组成，缺一不可。基站和移动站通过GPRS网络和Internet网络把差分信息和定位信息发送到服务器，服务器通过登录权限来给移动站传输差分协议以及对目标进行跟踪定位。文中介绍了差分GPS的原理以及差分协议，阐述了差分GPS对定位精度提高的原因。分析了差分协议的组成，并利用解码软件对RTCM SC-104差分协议进行了解码。在对基础知识充分理解之后，对系统总体进行了设计，说明了系统功能实现的可行性、原理及实现方案。第二步，对移动站和基站的终端硬件进行了设计，保证功能的实现。第三步，对移动站和基站的接收发送程序及网络服务器软件进行了编写。最后试验表明所设计的差分GPS目标跟踪定位系统能满足对目标的有效跟踪定位。
[Abstract]:For the target to perform a special task, the commander needs to track and locate the target continuously if he wants to know the exact position of the target in the monitoring range. For example, the specific position of Army special combat personnel in combat, the specific route and location of public security firefighters when they go to the police, and how vehicles in the 120 Ambulance Center seek the best rescue route. These problems are all to be solved by moving target tracking and positioning system. With the rapid development of domestic mobile communication technology, Internet and differential GPS technology, in civil and military fields, technicians are looking for suitable moving target tracking and positioning technology. A differential GPS moving target tracking and positioning system is designed. This system makes full use of the technical advantage of GPS GPRSU Internet, and the system designed and completed can track and locate the moving target accurately. The differential GPS target tracking and positioning system consists of three parts: server, base station and mobile station. The base station and mobile station send the differential information and location information to the server through GPRS network and Internet network. The server transmits the differential protocol to the mobile station and tracks the target through login permission. In this paper, the principle and protocol of differential GPS are introduced, and the reasons for improving positioning accuracy of differential GPS are expounded. The composition of the differential protocol is analyzed, and the RTCM SC-104 differential protocol is decoded by decoding software. After fully understanding the basic knowledge, this paper designs the whole system, and explains the feasibility, principle and implementation scheme of the system function realization. In the second step, the terminal hardware of mobile station and base station is designed to ensure the realization of function. The third step, the mobile station and base station receiving and sending program and network server software are written. Finally, the experimental results show that the differential GPS target tracking and positioning system can effectively track and locate the target.
