Abstract

Systems and methods for correcting a location of a terminal are provided. A processor in a position correction apparatus may select an action label from a plurality of action labels, and may associate the selected action label with the terminal. In various aspects, the selected action label may be selected by the processor based on a movement of the terminal. The processor may further select a correction algorithm for correcting the position of the terminal, where the selected correction algorithm may be selected from one or more correction algorithms that are associated with the selected action label. The processor may then correct the position of the terminal to a corrected position of the terminal using the selected correction algorithm.
