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.

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.

摘要： A method of recording satellite signals for later processing to derive position information. According to one aspect, the method comprises receiving and digitising first and second satellite signals using a first set of parameters; and receiving and digitising third and fourth satellite signals using a second set of parameters. A first time interval between the first and second satellite signals is longer than a second time interval between the reception of the third and fourth satellite signals. The first set of parameters is associated with relatively higher resource usage, while the second set of parameters is associated with relatively lower resource usage.

摘要： A method and apparatus for assisting the calculation of the position of a receiver device (1200), by observing a transmitted signal having a known structure. The method comprises: comparing (S220) the time of arrival, at a reference position (X1), of a first portion of the signal with the time of arrival at the receiver, at an unknown position (Y1), of a second portion of the signal; obtaining (S230) a local wave propagation model of the signal, the model comprising an estimate of the direction of propagation of the signal in the neighborhood of the reference position and unknown position; and using (S240) the direction of propagation and the result of the comparison to assist in the calculation of the unknown position relative to the reference position.

摘要： An interactive system in which information read from two or more tags (10, 12 or 10, 12′) jointly determines a process to be carried out. One of the tags may identify a user by for example his/her store loyalty card number or by a personal identifying tag (or card) in a cordless RF terminal and the other of the tags may be a RF-ID tag storing details of an action to be performed such as the number of credit points to be given to the loyalty card in response to a transaction or provide promotional information to the user. The process may comprise issuing a command to an action server (28, 30) to provide, or instruct the sending of, output information to a user, by for example over a radio link to a cellular telephone apparatus (18, 34, 36) or PDA, or displayed to the user on a video display unit (38).
