A synchronization correction method, a master device, and a slave device are provided. The method includes: transmitting a synchronization signal frame to a slave device during a first period of an isecond, where the synchronization signal frame includes a synchronization header, a first pulse per second (1PPS) signal, first time of date information, and first phase compensation information, where the first phase compensation information is configured to request the slave device to correct a transmission time point at which a first reference 1PPS signal is transmitted during a second period of the isecond; receiving the first reference 1PPS signal from the slave device during the second period of the isecond; and determining second phase compensation information transmitted to the slave device according to a receiving time point at which the first reference 1PPS signal is received during a first period of an (i+1)second.
