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