The present disclosure discloses a method for positioning an object in a positioning device and the positioning device thereof. The method comprises: transmitting a beam according to a preset mode; receiving a feedback signal sent from an object, wherein the feedback signal is a signal sent by an electronic tag on the object after receiving the beam, and the feedback signal correlates to an intensity of the beam when the electronic tag receives the beam; and determining a position of the object relative to the positioning device according to the feedback signal. Accordingly, the problem of cumbersome operation and poor reliability of manually recording storing locations of objects on a logbook by a user can be solved, and the effect of improving the convenience for positioning object can be achieved.

Systems (100) and methods (110) for operating a physical security surveillance system. The methods involve: detecting the constant unencrypted radio transmissions of mobile phones in order to capture in a cloud-based archive the identities, geographical trails, speeds and motions of most people nearby deployed units. Once recorded by a locally deployed sensor (104), the aggregated data (102) from the recorded mobile phones (106) is pooled in a globally inclusive database, synthesized, processed and filtered. On a paid-subscription basis, the data is accessible in a searchable archive that includes dozens of search parameters and filters. Users may visualize geographical trails of mobile phones on a multi-featured map, a geographically corresponding input of Google Street View, or a geographically corresponding input of video surveillance. Users may receive text message alerts when designated blacklisted individuals trespass in designated surveillance zones.

Embodiments of this application disclose a positioning method and an apparatus, to reduce a quantity of transmission points needed to calculate a position of a terminal, thereby reducing positioning calculation complexity. The method for calculating the position includes: receiving, by a terminal, positioning assistance information sent by a positioning entity, where the positioning assistance information includes a cell identity of a cell in which a to-be-measured transmission point is located, an identity of the to-be-measured transmission point, and positioning reference signal configuration information of the to-be-measured transmission point; measuring, by the terminal, the to-be-measured transmission point based on the positioning assistance information, to obtain a measurement result, where the measurement result includes positioning reference signal information of the to-be-measured transmission point; and sending, by the terminal, the measurement result to a positioning entity.

A wireless communicator receives location information items transmitted from a plurality of information terminals associated with a user. A selector selects, when a distance between the plurality of information terminals that is based on the location information items received by the wireless communicator is less than or equal to a threshold, a location information item corresponding to an information terminal having a highest priority level of priority levels assigned to the plurality of information terminals. A display indicates a current location of the user based on the location information item selected by the selector.

In one implementation, a method includes receiving versions of a message from a first satellite-based receiver and a second satellite-based receiver that both received a radio frequency (RF) transmission of the message, the message comprising a self-reported position of a transmitter of the message. The method also includes determining a time difference between a first arrival time of the RF transmission of the message at the first satellite-based receiver and a second arrival time of the RF transmission of the message at the second satellite-based receiver. The method further includes determining a measure of the likelihood that the self-reported position of the transmitter is valid based on the time difference between the first and second arrival times. The method still further includes transmitting an indication of the measure of the likelihood that the self-reported position is valid.

A disclosed method for a locating system comprises transmitting, by at least two transmitters on each of at least one transmitter platform, at least one signal, where each of the signals transmitted from a different transmitter is modulated at a different oscillation frequency, and the distance between the transmitters on each of the transmitter platforms is known. The method further comprises receiving, by a detector(s) on each of a target platform(s), the signal(s). When the detector(s) receives the signal(s), the signal(s) is focused at a location on the detector(s). Also, the method comprises determining an angle the signal(s) is being transmitted to the detector(s) from the transmitters by using the location(s). Further, the method comprises determining a relative position of each of the transmitter platform(s) with respect to the target platform(s) by using the angle(s) and by using the distance between the transmitters on each of the transmitter platform(s).
