NAVIGATION SYSTEM AND GPS TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide a navigation system capable of quickly starting a navigation function of a GPS terminal without complicating the structure. SOLUTION: A GPS monitor server 3 receives on the ground the GPS signal transmitted from a GPS satellite 2, and a FM multi-broadcaster station 4 transmits by an electric wave signal the GPS auxiliary information including the almanac and ephemeris data in the navigation message of the GPS signal received by the GPS monitor server 3. The GPS terminal 1 receives the GPS auxiliary information, and starts to receive the GPS signal to be transmitted from the GPS satellite 2.
