Abstract:
1. A method for modifying navigation information comprising steps of: providing a navigating route for a carrier; determining at least one characteristic points according to the navigating route; acquiring a corresponding characteristic information of the at least one characteristic points through a storage media unit of a navigation apparatus, wherein the characteristic information is an azimuth angle, an attitude angle or the combination thereof; detecting moving status of the carrier through a sensing module of the navigation apparatus so as to obtain a status information with respect to the carrier while the carrier is moving, wherein the status information is an azimuth angle, an attitude angle or the combination thereof; comparing the characteristic information with the status information to determine whether the characteristic information is corresponding to the status information or not through a signal processing unit of the navigation apparatus; continuing to monitor the moving status of the carrier if the characteristic information is not corresponding to the status information through the sensing module of the navigation apparatus; and modifying coordinate position of the carrier to a position corresponding to the characteristic point on the navigating route if the characteristic information is corresponding to the status information through the signal processing unit of the navigation apparatus.
