摘　　要：为了解决MT测深仪在GPS配件损坏或GPS信号较差情况下不能工作或采集时间记录出现紊乱的问题,给出了利用GPS(global positioning system)和RTC(real-time clock)解决的方案,并在自主研发的长周期MT测深仪CLP中进行了实施。介绍了系统设计思路与电路的设计原理、主要程序设计算法,给出了野外测量结果,对结果进行了分析,分析结果说明该仪器的基于GPS和RTC的时钟功能可胜任大地电磁测深工作要求。In order to solve that some MT instruments can not work normally or time record error without GPS signal or its GPS device damaged, a method to design clock and timing based on GPS （global positioning system） and RTC （real-time clock） was proposed, and was used in CLP, a long-period MT instrument made by China Uni- versity of Geosciences. The design method, circuit schematic and the main flow chart were introduced, and an experiment result was showed. The experiment result shows that the clock and timing function based on GPS and RTC can solve the above problem.
