摘　　要：为了满足新型小型光测设备要求,设计了一体化GPS时统终端;采用u-blox5技术的GPS授时芯片,设计了一种集成GPS信号接收、捕获及产生、同步信号(时间起点与GPS秒脉冲信号同步)输出及远程发送、时间标准IRIG-B(DC)直流码输出以及数据通信等功能于一体的时统终端;实践结果表明系统体积小、集成度高、性能可靠,同步精度<1μs。The integrated GPS time system was designed in order to meet the requirements of model small optical measurement equip- ment. Using u-blox5 technology of GPS timing chip, design a kind of integrated GPS signal receiving, capture and generation, synchronous signal （start time and GPS second pulse signal synchronous） output and a remote transmission, standard time IRIG--B （DC） DC output and data communications and other functions in one of the time terminal, the results show that the volume of the system small, high integration, reliable performance, synchronization accuracy 〈lus.
