Claim:
A positioning device comprising: a reception means for receiving a signal transmitted from a positioning satellite; a clocking means for clocking time; a first reception control means for receiving route information required for positioning from the positioning satellite via the reception means; a storage means for storing the received route information; a second reception control means for receiving time information indicating time from the positioning satellite via the reception means; a time correction means for correcting the time clocked by the clocking means based on the received time information; and a positioning means for capturing the signal transmitted from the positioning satellite based on the time clocked by the clocking means and performing positioning based on the transmitted signal and the route information stored in the storage means; wherein the first reception control means intermittently receives the route information at a predetermined reception interval, and the second reception control means intermittently receives the time information even during a period in which the positioning by the positioning means is not performed.
