摘　　要：为了掌握被测量目标现场的更多真实信息,提出了图像全球定位系统(ImageGlobalPositioningSystem,IGPS)接收器的概念。IGPS接收器是在获取定位信息的同时采集被测量目标的现场真实图像。证明了IGPS的信息论依据,得出了基于贝叶斯的定位精度原理,实现了IGPS的应用实例。定位信息和图像信息通过公用移动网络的通用分组无线业务(GeneralPacketRadioService,GPRS)传输到接收信息中心。理论与实验结果证明了IGPS接收器的优越性和可行性。结果表明,通过IGPS接收器可以掌握目标更多的信息。In order to grasp more real reformation of traced target, the image global positioning system （IGPS） receiver was bring forward. The real images of measuration place were gotten while receiving global positioning information in the IGPS receiver, The information principle about IGPS was proven, Positioning accuracy principle of IGPS basing on Bayes Decision Ruler was drawn. One application of 1GPS was realized, The positioning information and images were transmitted to the server in information center through public mobile network general packet radio service （GPRS）. The feasibility and advantages of IGPS were proven by theory and experiment. The result indicates more real information of measuration target may get through IGPS.
