Abstract: The present invention relates to a method for removing a side peak of a BOCsin(n,n) signal, comprising: generating a correlation function of a local BOCsin(n,n) signal and a received BOCsin(n,n) signal in synchronization of the BOCsin(n,n) signal among sine phase binary offset carrier (sine phase BOC) signals; acquiring an absolute value oaf the correlation function; and combining the correlation function with the absolute value of the correlation function. According to the present invention, since only the autocorrelation function is used in combination, an arithmetic operation is simple as compared with the prior art. Since the magnitude of a main peak is not reduced, a signal tracking function is improved and thus reliable code tracking is possible. Also, since the side peak is completely removed, no signals are acquired in the side peak of the BOC autocorrelation function and thus noise is remarkably reduced. In addition, since a single branch correlator is used, a circuit is easily implemented.

Abstract: PURPOSE: A method for determining a position of a movable body of a navigation system is provided to calculate a driving distance of the movable body per unit hour by setting a driving distance conversion factor according to a driving speed of the movable body, thereby enabling to reduce errors. CONSTITUTION: A method for determining a position of a movable body of a navigation system is as follows. The reliability of position information received from a GPS(Global Positioning System) satellite when driving the movable body is determined(S200,S201). When the reliability of the position information is higher than a preset standard, a position of the movable body is determined by reflecting the position information to a position determination algorithm(S202). The determined position information of the movable body is displayed on a digital map by map-matching(S203). When the reliability of the position information is lower than the preset standard, whether or not a driving speed of the movable is higher than a preset speed is determined based on the number of pulse signals per unit hour generated by a speedometer by driving the movable body(S204,S205). When the driving speed of the movable body is higher than the preset speed, a driving distance per unit hour of the movable body is calculated by setting a driving distance conversion factor based on the number of the pulse signals(S206,S208).
