The present invention relates to a satellite antenna integrated time-synchronization device for generating a time-synchronization signal from a satellite signal received from a satellite, which includes a case, a 1PPS synchronization module which is disposed in the case and is configured to generate at least a 1PPS signal from the satellite signal, and a signal processing means which is disposed in the case and is configured to generate an IRIG signal and communication data using the 1PPS signal input from the 1PPS synchronization module.

A processor controls an oscillation circuit such that a frequency of a clock signal is close to a reference frequency based on a frequency of a carrier wave of a standard radio wave and the frequency of the clock signal. In this manner, since the processor controls the frequency of the clock signal by using the carrier wave of the standard radio wave of which the frequency is managed with high accuracy, it becomes possible to improve accuracy of an internal time.
