A method comprises using a first directional transceiver (A) to determine a first angle (&#x3b1;) between a first vector (V) from the first directional transceiver to a second directional transceiver (B) and a second vector (V) from the first directional transceiver to a third directional transceiver (C), using the second directional transceiver to determine a second angle (&#x3b1;) between a third vector (V) from the second directional transceiver to the first directional transceiver and a fourth vector (V) from the second directional transceiver to the third directional transceiver, calculating a location, relative to a local coordinate system, of the third directional transceiver using the first and second angles and locations in the local coordinate system of the first and second directional transceivers, the local coordinate system being defined relative to the locations of the first, second, and third directional transceivers, and calculating an orientation relative to the local coordinate system of the first directional transceiver using directions of the first and second vectors relative to the first directional transceiver and the locations in the local coordinate system of the first, second and third directional transceivers.

Determining location and orientation of directional transceivers

Method, apparatus, and computer program product example embodiments provide short-range communication based location finding. According to an example embodiment of the invention, a method comprises receiving, by a first transceiver of an apparatus mounted on a moveable platform, from a remote device, one or more wireless packets including information packets containing angle of arrival information from the remote device, wherein the moveable platform is in motion relative to the remote device; determining in the apparatus, at least a first angle of arrival from the received angle of arrival information; and generating distance estimation data in the apparatus relative to the remote device, based on the determined first angle of arrival.

Method, apparatus, and computer program product for high accuracy location determination

A portable battery-powered communications device is configured to operate in a bidirectional communications mode in which voice and/or data is communicated in a bidirectional manner using a bi-directional communications protocol; and to operate in an emergency beacon mode. When the device is in the emergency beacon mode the device is configured periodically to transmit an emergency positioning message at maximum power using the bi-directional communications protocol, transmission of the emergency positioning message defining a beacon transmit period; optionally, to listen for transmissions using the bi-directional communications protocol in a beacon response period immediately following the beacon transmit period; and to refrain from powering transmit and receive circuitry of the device other than during the beacon transmit period and the beacon response period.

Emergency beacons

A method, comprising: detecting, at an apparatus, one or more radio signals from a first location; using the one or more detected radio signals to estimate a bearing from the first location; and using the bearing estimate to determine whether further detection of one or more radio signals is required before positioning the apparatus; and positioning of the apparatus using a bearing and constraint information.

Method, and apparatus for determining the position using radio signals

A method including receiving signals associated with multiple antenna elements; obtaining a parameter of the received signals for at least some of the multiple antenna elements; testing the obtained parameters; if the test fails, rejecting the received signals for use in positioning the apparatus; if the test passes, using the received signals for positioning the apparatus.

Method and apparatus for testing received signals in a radio signal positioning system

The invention relates to an apparatus and method for estimating the distance between a transmitter and a receiver. A method comprising obtaining a signal from a receiver; determining whether the signal more likely propagated through a line-of-sight (LOS) radio channel or a non lme-of-sight (NLOS) radio channel; using a model including parameters selected according to the radio channel to estimate the distance between the receiver and a transmitter which sent the signal.

Distance estimation

Method, apparatus, and computer program product example embodiments provide short-range communication based direction finding. According to an example embodiment of the invention, a method comprises transmitting by a target device, information in one or more advertising packets, including preferences of the target device for using data signing associated with direction finding; and receiving by the target device from a tracker device, one or more direction finding request packets including a request for data signing corresponding with the target device preferences.

Method, apparatus, and computer program product for short-range communication based direction finding

A system for indicating the relative direction of a target object or location as determined from the current position of a wireless communication device. The system employs Direction of Arrival determination using an antenna array for indicating the direction of a target device and includes facilities to activate a location-indicating transmission in a target device, the ability to request that a location-indicating transmission be activated in a remote target device, relevant information reception from a target device and the display of all potential target devices within effective transmission range of the wireless communication device.

System and methods for direction finding using a handheld device

A system for enhancing the performance of a wireless communication device (WCD) while executing a direction of arrival (DoA) estimation. The performance may be improved through device management, and may include the collection of information from one or more sensors installed within the WCD. The sensor information may initially be used to determine an appropriate configuration for the device. Further, the sensor information may also be used to affect the behavior of the device while performing the DoA estimation.
