Zeitkorrekturvorrichtung, Uhr mit der Zeitkorrekturvorrichtung und Zeitkorrekturverfahren

摘要

A time correction device has a reception unit that receives satellite signals transmitted from positioning information satellites orbiting the Earth; a time correction information storage unit that stores time correction information for correcting time information produced by a time information generating unit; and a time information correction unit for correcting the time information based on the time correction information. The satellite signals are transmitted by individual positioning information satellites, and contain a time-related information part denoting time-related information that is kept by each satellite, and a satellite information part denoting satellite information other than the time-related information. The time correction information is generated based on the time-related information. The reception unit receives the satellite signal during the signal period in which the time-related information part can be received, and does not receive the satellite signal during the signal period in which the satellite information part can be received.
