POSITION ERROR CORRECTION METHOD USING TRANSMISSION INTERVAL ADJUSTMENT OF NAVIGATION SIGNALS AMONG REFERENCE STATIONS

摘要

The present invention relates to a new method for compensating a position error by adjusting transmission intervals of navigation signals from reference stations, which calculates an accurate position of a receiver using navigation signals transmitted from a plurality of reference terminals without using a separate position compensating system at a receiving terminal. In order to accomplish this, disclosed is a method for compensating a position error by adjusting transmission intervals of navigation signals from reference stations comprising: a receiving step which periodically receives navigation signals from at least four reference terminals, wherein positions of the reference terminals on earth are known; a synchronizing step which performs a synchronous control for periodically synchronizing time among reference terminals; an error calculating step during which the respective reference terminals compare a position calculation value using the navigation signal received during the receiving step with an actual coordinate values to calculate a position error; a transmitting step which generates a navigation signal for calculating the position of the receiving terminal by reflecting the position error calculated in the error calculating step and retransmits the navigation signal; and a position calculating step which receives the navigation signal transmitted during the transmitting step and calculates a position.
