METHOD FOR MEASURING USER POSITION IN REAL TIME OF DIFFERENTIAL GLOBAL POSITIONING SYSTEM

摘要

PURPOSE: A method for measuring a user position in a real time is provided, which measures a user position in a real time using an estimated special correlation distance. CONSTITUTION: A method for measuring a user position in a real time comprises the steps of: (410) receiving an error amending value from a plurality of reference station; (420) receiving a clock information and an orbit information of a satellite from a position information supply satellite; (412) computing an amend error; (413) computing a correlation distance using a data window; (414) performing a Karman filtering; and (415) measuring a user position. Therefore, the accurate value is obtained when the user position is computed and a variety files are used.
