摘　　要：载波相位实时动态差分技术(RTK)是一种高精度GPS定位技术,定位精度达到"厘米"级,它在实际道路驾驶技能自动化考试系统中的成功应用,解决了考车行驶过程中的距离测量问题。给出了该技术在道路考试中实现"车车"之间、"车线"之间距离检测算法及在具体考试项目里的典型应用,并指出应用过程中需要注意的事项。Real Time Kinematic （RTK）, based on the use of carrier phase measurements of GPS, is a high-precise posi- tioning technology. The positioning accuracy achieves centimeters. It was successfully applied in automatic test system for testing a person＇s ability to drive a vehicle and solved the problems of dynamic distance measuring. And in the paper, the algo- rithm used to measure distance between cars and between cars and road surface markings was introduced. The typical applica- tion of the system in the driving test subjects and some precautions in the application were proposed as well.
