Abstract

The invention discloses a time code measuring device based on satellite common-view. The device comprises an antenna, a common-view receiving unit, a remote data transmission unit, a time holding unit, a time signal measuring unit, a measuring result accurate processing unit and a calibration result output unit. According to the time code measuring device, the common-view comparison mode is adopted to perform data interaction with the common-view receiver of a time keeping laboratory so that the error caused by time reference in case of time code measurement can be eliminated and the accuracyof time code field calibration can be enhanced.

Description

technical field [0001] The invention relates to the technical field of time code measuring devices, in particular to a time code measuring device based on satellite common viewing. Background technique [0002] With the development of technology, the importance of time synchronization in various electronic systems, especially weapon systems, is increasingly reflected. In order to complete multi-service, multi-system information fusion and coordinated operations, each system must work within a unified space-time coordinate system. To this end, many systems are equipped with high-precision time unification devices. [0003] The time statistics equipment obtains the initial time by receiving satellite navigation system signals such as Beidou or wired signals such as IRIG-B codes, internally maintains the time through rubidium atomic clocks or high-stable crystal oscillators, and outputs 1PPS, 1PPM, 1PPH, and IRIG-B (DC) externally Code, IRIG-B (AC) code, TOD, NTP, PTP and oth...
