英文摘要：

Global positioning system （GPS） has been widely applied in the fields such as positioning, navigation and precise time service. The performance index and output data format of GSU-36 GPS receiver produced by KODEN Corporation are introduced in this paper. Based on GPS technology, the hardware interface between the GPS receiver and single chip microcontroller as well as the design of software is given in detail. The technical program which uses GPS to achieve the time synchronization between the detection instrument and current interrupter is successfully applied in the detection system of coating defects of buried pipelines. The application result shows that the plan proposed in this paper is correct, and the method of communication between the GPS receiver and single chip microcontroller also has a broad prospect for the development in other application fields which demand time synchronization.
