The utility model discloses a high-reliability timing device which comprises a master control MCU module, a battery module, a power management module, a receiver power supply control module, a satellite antenna, an antenna detection module, a satellite receiver, a crystal oscillator module, a time difference measurement module, an external reference clock input module and a time code drive module. The satellite antenna and the satellite receiver form a first reference clock source in the time calibration device, the external reference clock input module is connected with the external reference clock output source to form a second reference clock source in the time calibration device, and the time service reliability of the time calibration device is improved through the arrangement of the two reference clock sources; through the arrangement of the antenna detection module and the receiver power supply control module, when the satellite antenna is in an open circuit or short circuit abnormity, the receiver pow
