    摘要: A positioning method that calculates a lower accuracy positioning solution and applies an offset to the lower accuracy positioning solution to form a final positioning solution if a higher accuracy positioning solution is unavailable. The offset represents a difference between the lower accuracy positioning solution and the higher accuracy positioning solution at a point in time when the higher accuracy positioning solution was last available.

    摘要: A method of determining an indication of the position of an electronic device. The method comprises: obtaining (100) information relating to a radio signal received by the device, the radio signal comprising transmissions from one or more satellites of a satellite-positioning system, from which information an inference can be made about the true position of the device at the time the signal was received; obtaining (110) a plurality of hypotheses about the true position of the device; evaluating (120, 130, 140) the plurality of hypotheses, comprising assessing a degree of consistency between the information relating to the radio signal and the hypotheses; based on the outcome of the evaluations, selecting (150) one or more of the hypotheses; and outputting (160) an indication of the selected one or more hypotheses.
