Abstract

The invention discloses a boat-carrying information system frequency standard calibrating device, comprising a time service type satellite receiving module and a reference frequency signal conditioning module. The time service type satellite receiving module is in connection with a reference selection module through a self-taming frequency standard module; the reference frequency signal conditioning module is in connection with the reference selection module; the reference selection module is separately in connection with an error multiplier and a frequency measuring module, wherein the error multiplier is separately in connection with the frequency measuring module and a measured frequency signal conditioning module; the frequency measuring module is separately in connection with the measured frequency signal conditioning module and a key display module. The invention also provides a boat-carrying information system frequency standard calibrating method. The boat-carrying information system frequency standard calibrating device can perform field calibration on boat-carrying information system frequency standards, and avoid disassembling a boat-carrying information system and sending the boat-carrying information system to a metering station for calibration; the device requires no higher frequency standard, and can reduce frequency standard calibration time and cost.

Description

technical field [0001] The invention belongs to the field of frequency calibration, and in particular relates to a frequency standard calibration device and calibration method for a shipborne information system. Background technique [0002] Temperature compensated crystal oscillators and rubidium atomic frequency standards are generally used as frequency standards in shipborne information systems. Due to the inherent characteristics of temperature compensated crystal oscillators and rubidium atomic frequency standards, the frequency accuracy indicators will decline as time goes by. Therefore, in order to meet the frequency accuracy index requirements of the shipboard information system for the temperature-compensated crystal oscillator and the atomic frequency standard, it is necessary to calibrate the temperature-compensated crystal oscillator and the atomic frequency standard regularly. At present, it is generally used to disassemble the temperature compensated crystal os...
