    摘要: A method comprises using a first directional transceiver (14A) to determine a first angle (α1) between a first vector (V1) from the first directional transceiver to a second directional transceiver (14B) and a second vector (V2) from the first directional transceiver to a third directional transceiver (14C), using the second directional transceiver to determine a second angle (α2) between a third vector (V3) from the second directional transceiver to the first directional transceiver and a fourth vector (V4) 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.

    摘要: 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.

    摘要: 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.
