The present invention provides an augmented reality service providing device, including: a sensing unit to photograph an object and to measure a current position of a mobile terminal; a communication unit to measure a communication distance between the mobile terminal and the object; a control unit to control to repeat a plurality of times the measurement of the current position and the communication distance while the mobile terminal is moving; a calculation unit to calculate an estimated position of the object based on the current position and the communication distance measured repeatedly a plurality of times; and a display unit to display virtual information on the object on the estimated position of the object.

A system for locating an object in a volume of space can include a communication device of the object disposed in the volume of space, where the communication device broadcasts a first communication signal into the volume of space, where the first communication signal includes a first identification of the object. The system can also include multiple integrated sensor devices disposed in the volume of space, where each integrated sensor device includes at least one sensor, at least one receiver, and at least one transmitter, where the at least one receiver of a subset of the integrated sensor devices receives the first communication signal, where each of the subset determines a signal strength of the first communication signal. The system can further include at least one access controller that receives at least one second communication signal sent by the subset.

Systems and methods for localizing and tracking mobile objects are provided. A method includes determining an initial location of a node in a multi-hop network based on multi-lateration from an unmanned aerial vehicle. The method also includes applying an adaptive aperture to address a non-uniform velocity of the node based on the turn and a velocity vector. A determination whether localization for the node can be implemented using first hop nodes in the multi-hop network is made. In response to a determination that localization cannot be implemented using the first hop nodes, inertial sensor measurements associated with the node are accessed and the inertial sensor measurements are integrated with the adaptive aperture to improve localization accuracy.

Disclosed is a method of identifying location information of a signal source, the method including: identifying, at a first position, first position information and first posture information of an UAV equipped with a linear array antenna; identifying, after identifying a first measured azimuth between the signal source and the antenna at the first position, a first corrected azimuth; identifying, at at least one second position, at least one piece of second position information and at least one of second posture information of the UAV; identifying, after identifying at least one second measured azimuth between the signal source and the antenna at the at least one second position, at least one second corrected azimuth; and estimating the location information of the signal source by using the first position information, the first posture information, the first corrected azimuth, the second position information, the second posture information, and the second corrected azimuth.

Disclosed are techniques for wireless sensing. In an aspect, a user equipment (UE) receives, from a network entity, volume-related information associated with at least one target object, the volume-related information including an estimated position of the at least one target object, an estimated size of the at least one target object, an estimated volume of the at least one target object, an estimated orientation of the at least one target object, an estimated shape of the at least one target object, or any combination thereof, and performs a sensing procedure with the network entity to determine one or more characteristics of the at least one target object based on at least the volume-related information.

A tracker device for a first responder including a radio configured to receive a first radio signal from an emitter, and receive a second radio signal from an unmanned aerial vehicle (UAV). The second radio signal includes at least one data packet including location information associated with the emitter. Processing circuitry in communication with the radio is configured to determine at least one location parameter associated with the emitter based on the first radio signal and the location information of the at least one data packet of the second radio signal.

Disclosed is a technique that can provide one or more countermeasures against spoofers. An antenna, movable in space, is used to receive space vehicle (SV) signals that appear to be associated with a plurality of space vehicles of a global navigation satellite system (GNSS). SV signals are identified that have similar signal power and/or phase signatures that respectively appear to be associated with at least a first space vehicle and a second space vehicle of the GNSS. An existence of a spoofer is identified based at least in part on the identification of SV signals that have similar signal power and/or phase signatures that respectively appear to be associated with at least the first space vehicle and the second space vehicle of the GNSS.

Positioning of one or more user equipments (UEs) is performed using broadcast common sounding reference signals (SRS) resources for positioning. The common SRS that is broadcast by a UE is received and measured by one or more base stations and one or more other UEs. The other UEs may have known positions and may server as anchor nodes for positioning. The other UEs may have known positions and may serve as a positioning (anchor) node or may have unknown positions and may be jointly positioned with the target UE. During joint positioning, each of the other UEs may similarly broadcast a common set of SRS that is received and measured by the base stations and other UEs for positioning. An angular measurement of the SRS broadcast by one or more UEs may be measured and used to resolve mirror symmetry in positioning solutions.

A method and device determines an evolving position of a device using electromagnetic interference, which is jamming electromagnetic navigation signals. An antenna arrangement receives both the electromagnetic navigation signals and the electromagnetic interference. A discerned position is determined for each of one or more jamming antennas emitting the electromagnetic interference. A detection circuit determines each discerned position from the electromagnetic interference received at the device and at least one measurement of the evolving position using the electromagnetic navigation signals. The evolving position of the device is determined while the electromagnetic interference prevents subsequently measuring the evolving position using the electromagnetic navigation signals. An evaluation circuit determines the evolving position from the electromagnetic interference received at the device and from each discerned position of the one or more jamming antennas.
