基于GPS板的时差比相频标比对系统的研制

摘要

The frequency performance of Communication device can calibrated with GPS frequency comparator. The design projects of GPS frequency standard and phase comparing unit and time difference comparing unit are described in detail and the software design scheme of system is also given out in this paper. The key technologies are used to improve measurement accuracy of comparator.%应用GPS技术研制频标比对系统可对野外环境条件下的通信设备进行快速、便携的时间频率校准.详细描述了系统中GPS频率标准源以及比相法、时差法频标比对单元的设计方案和软件设计思路,并给出了设计方案中关键技术解决途径.该系统经校准完全满足要求,并在计量技术机构得到应用.
