摘　　要：差分GPS定位能将卫星误差和星历误差消除,能把电离层延迟和对流层延迟误差部分消除,并能减小美国政府SA政策对卫星定位精度的影响,使得定位精度大大提高。所以,差分GPS定位技术在最近几年中得到了迅速发展和广泛应用。伪距差分定位技术在武警车辆遥测遥控方面的应用,为武警巡逻车辆的快速调度和合理安排很有帮助,大大提高了武警部队在治安和追捕逃犯方面的能力。因此,一些先进国家都建立了这一系统。在我国一些城市也开始建立这一系统,具有很大的应用前景。Differential GPS satellite positioning can eliminate error and error-calendar, which can eliminate the errors of ionosphere delay and troposphere delay, and can reduce the impact of SA policies on satellite from the US government, greatly enhancing positioning accuracy. Therefore, the differential GPS positioningtechnology has been the rapidly developed and applied in recent years. Application of pseudo--distance differential positioning technology in remote telemetry armed police vehicles gives a great help for armed police patrol vehicles for rapid activation and reasonable arrangements, greatly improving the security and the armed police force to hunt down fugitives in the area. Thus, some foreign countries have established this advanced system. Some cities in China have begun to establish this system, which will have the application foreground.
