| Abstract: | The frequency performance of the communication device can be calibrated with GPS frequency comparator. The design projects of the GPS frequency standard, phase comparing unit and time difference comparing unit are described in detail, and the software design scheme of the system is also given in this paper. The key technologies are discussed to improve the measurement accuracy of comparator. This calibrated system fully meets the requirement and has been used in the metrological organizations. |
