Electronic device positioning method, determining satellite velocity in relation to electronic device for different satellites, and generating reference data using delta range measurements and velocities

摘要

The method involves determining satellite velocity in relation to an electronic device for each of the four different satellites. The delta range measurements and velocities are used for generating reference data to find the frequency error of the local time data and the position of the electronic device, and the minimum value of reference data is searched. An Independent claim is also included for a system for carrying out electronic device positioning method.
