Method and apparatus providing improved position estimate based on an initial coarse position estimate

摘要

Determine that the technology of device location is based on initial coarse position and estimates equipment, location estimation multiple transmitters of the export based on initial (less accurate). In a method, modified (more accurate) the location estimation transmitter of coarse position estimation equipment is received. The location estimation of modified equipment is initialised (for example, coarse position estimation). Vector is updated, is then calculated based on initial and corrected location estimation equipment and initial and corrected location estimation transmitter. Then the location estimation of modified equipment is updated based on update vector. The update for calculating the location estimation for updating vector and modified equipment, which can be repeated as many times, obtains more and more estimations.
