Abstract
A positioning system includes: a terminal apparatus and an information supply apparatus capable of communicating with the terminal apparatus. The information supply apparatus includes: external timing signal generating means for generating an external timing signal constituted by external events; satellite time information generating means; external timing signal correcting means; and transmitting time information generating means. The terminal apparatus includes: communicating means; terminal timing signal generating means for generating a terminal timing signal constituted by internal events; clock number recording means; interevents clock number information generating; time difference information generating means for generating time difference information which indicates times between reception of the external events and generation of the internal events based on the interevents clock number information; and internal time information generating means for generating internal time information.
