发明名称 TIME DIFFERENCE OF ARRIVAL BASED POSITIONING WITH CALCULATION OF CORRECTION FACTORS FOR COMPENSATING CLOCK OFFSETS OF UNSYNCHRONISED NETWORK STATIONS
摘要 FIELD: radio engineering, communication.SUBSTANCE: invention presents a method, a device and computer program product for clocking using the relative behaviour of clocks of individual receiving stations as well as corresponding modelling to derive a time difference of arrival of a signal from a user device which can be used to correct the time difference of arrival based on the modelled clock behaviour and leads to a correct clocking of received user signals, which is applicable to a plurality of pairs of receiving stations and transmitted beacon signals and allows to correct location estimation of a user device.EFFECT: enabling estimation of the location of a mobile device without the need to synchronise clocks at different receiving stations.15 cl, 6 dwg
