Partially synchronized multilateration or trilateration method and system for positional finding using RF
Systems and methods for determining a location of one or more user equipment (UE) in a wireless system can comprise receiving reference signals via a location management unit having two or more co-located channels, wherein the two or more co-located channels are tightly synchronized with each other and utilizing the received reference signals to calculate a location of at least one UE among the one or more UE. Embodiments include multichannel synchronization with a standard deviation of less than or equal 10 ns. Embodiments can include two LMUs, with each LMU having internal synchronization, or one LMU with tightly synchronized signals.
Inspection tracking system
A system and method to verify that the driver or operator of a vehicle or piece of equipment has completed a 360-degree walk-around inspection of the vehicle/equipment. The vehicle/equipment will be equipped with an electronic beacon that detects the direction of the driver/operator via a mobile electronic device that the driver/operator carries. As the operator walks around the vehicle/equipment, the electronic beacon installed on the vehicle/equipment recognizes the location of the mobile electronic device as the driver/operator walks around the vehicle/equipment performing their inspection. In certain embodiments, the electronic beacon and mobile electronic device determine the operator's inspection are Angle of Arrival and Angle of Departure relative to each electronic beacon. The determination may require different combinations of transmitters and receivers. In another embodiment, multiple antennas, mounted on the vehicle/equipment and/or mobile electronic device, provide the location details of the driver/operator in correlation to the vehicle/equipment.
DIRECTIONAL ANTENNA OBJECT DETECTION
An object detection system comprises two or more directional antennas arranged such that lobes of the antennas overlap within a designated area or volume. An electronic device detecting signals from at least two of the directional antennas is determined to be inside the area/volume, and a device detecting signals from none of the antennas or only one antenna is determined not to be inside the area/volume. In this manner, the system determines when a user has placed an electronic device within the area/volume, logs the time the electronic device is within the area/volume, and reports the logged time to the user and/or a central system. The area/volume can comprise a platform, a box, or other confined space.
Reference Point Selection for OTDOA in a Non-Terrestrial Network
A positioning server is configured to determine a set of anchor points to be used in a positioning method for a user equipment, wherein each of the anchor points is associated with a type of anchor point comprising a terrestrial type or a non-terrestrial type, select a subset of the set of anchor points based on the types of the anchor points, select one anchor point from the subset of anchor points as a reference anchor point based on an expected quality of a positioning reference signal (PRS) transmission received from the anchor point, transmit to the UE a PRS configuration for each of the anchor points and indicating to the UE the reference anchor point and instruct each of the anchor points to transmit respective PRSs in accordance with the PRS configuration.
System and method for determining vehicle position by triangulation
A system and method for determining the location of a vehicle when GNSS signals are not available use triangulation between one or two radio transmitters and, respectively, two or one radio receivers mounted on the vehicle. The distance between each radio transmitter and/or each radio receiver can be determined according a phase difference between received radio signals. The radio signals can have the geographical location of the radio transmitter included therein. Utilizing the demodulated geographical location of each radio transmitter and the distance between the radio transmitter and each radio receiver, triangulation can be used to determine the geographical location of the vehicle.
Deployable navigation beacons
Deployable navigation beacons can be deployed from a vehicle, such as an unmanned aerial vehicle (UAV), in an event of a loss of position or orientation of the vehicle. After deployment of the navigation beacons, the vehicle may detect locations of the navigation beacon, which may define a surface that may include surface features. The vehicle may then perform control operations based on the resolved locations. For example, UAV may maneuver to land proximate to the navigation beacons after resolving locations of the navigation beacons as a continuous surface. The navigation beacons may output a visual signal (e.g., a light), a auditory signal (e.g., a sound), and/or a radio signal. In some embodiments, each navigation beacon may include a different or unique signal.
AIRCRAFT GUIDANCE WITH TRANSMITTING BEACONS
Aircraft guidance with transmitting beacons is disclosed. An example apparatus includes a transceiver of an aircraft to receive signals from deployed beacons, a signal analyzer to analyze the signals to determine distances of the respective beacons relative to the aircraft, and a position calculator to calculate a positional zone of the aircraft based on the distances.
Method for Sending an In-band Positioning Signal and In-band Positioning System in a Communication Network
Provided is a method for sending an in-band positioning signal and in-band positioning system in a communication network. The system includes: a Position Management Station (PMS), arranged to manage one or more Position Service Stations (PSSs) and provide a synchronization reference clock for the one or more PSSs; a positioning center network element, arranged to provide position estimation information for a terminal based on position information of the one or more PSSs and send the position estimation information to the terminal; and the one or more PSSs, of which each PSS uses a same frequency band used by the communication network and is arranged to generate an in-band positioning signal for measuring a distance, regulate a sending clock of the in-band positioning signal according to a difference value between a local sending clock and the synchronization reference clock and send the in-band positioning signal to the terminal.
APPARATUS, SYSTEM AND METHOD OF A ONE-SIDED LOCATION MEASUREMENT
Some demonstrative embodiments include apparatuses, devices, systems and methods of one-sided location measurement. For example, an apparatus may include circuitry and logic configured to cause a wireless station to transmit an announcement element to announce a Non-Data Packet (NDP) sounding transmission including a plurality of sounding preambles, the announcement element including at least a measurement type field to indicate a type of a one-sided location measurement, and one or more configuration fields including configuration information to configure the one-sided location measurement based on the NDP sounding transmission; and to transmit the NDP sounding transmission subsequent to the announcement element.
Contextually Configuring Consistent Proximity Beacon Identifiers
Administration and consistency of proximity beacon naming within one or more venues is improved by use of a mobile device to discover ranges of the beacons, and upon discovery, determining a location of a mobile computing device within the venue; receiving at the location by the mobile computing device one or more identifiers from one or more proximity beacons within range of the location; and updating by the mobile device at least one of the one or more identifiers according to a proximity beacon naming policy.
