Position validation

摘要

A method of determining an indication of the position of an electronic device. The method includes: obtaining (100) information relating to a radio signal received by the device. The received radio signal are 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. The method also involves obtaining (110) a plurality of hypotheses about the true position of the device; and evaluating (120, 130, 140) the plurality of hypotheses by assessing a degree of consistency between the information relating to the radio signal and the hypotheses. Using the outcome of the evaluations, the method also includes selecting (150) one or more of the hypotheses; and outputting (160) an indication of the selected one or more hypotheses.

1. A method of determining an indication of the position of an electronic device, the method comprising:
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 different hypotheses about the true position of the device, wherein each hypothesis comprises at least one of:
a position in two or more spatial dimensions;a set of positions; and a range of positions;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; andoutputting (160) an indication of the selected one or more hypotheses.
