    Abstract: This specification relates to estimation of a location of a mobile device using one or more locator devices. This specification describes an apparatus comprising: means for receiving, from one or more locator devices, each locator device comprising an antenna array, information indicative of a bearing from the antenna array of each of the one or more locator devices to a mobile device; means for determining parameters of a Kent distribution for each of the one or more locator devices based on the received information and predetermined characteristics of the antenna array; and means for determining an estimated position of the mobile device by performing an optimisation process on an objective function that is dependent on the Kent distribution parameters for each of the one or more locator devices.

    Abstract: An apparatus, method and computer program is described comprising: determining that a first mobile object requires positioning assistance based on one or more predetermined criteria, wherein the predetermined criteria includes whether one or more properties of a planned or predicted future position of the first mobile object have been identified as insufficient, or are predicted as being insufficient, for determining the position of the first mobile object with a required level of accuracy; and responsive to said determination, causing deployment of one or more movable devices (e.g. UAVs) to a target position for providing the required positioning assistance to said first mobile object.

    Abstract: Inter-alia, a method is disclosed comprising: obtaining, for at least one reference position, an estimate of a representative direction from a node of a communication network to the at least one reference position based on information indicative of at least one directional measurement, the directional measurement being indicative at least of a propagation direction of a signal communicated between the at least one reference position and the node of the communication network; obtaining, for the at least one reference position, a weighted estimate of the representative direction based on at least an angular weighting function for the at least one reference position, the angular weighting function being representative at least of an aperture of at least one antenna of the node of the communication network; and obtaining information indicative at least of an orientation and/or position of the node of the communication network at least based on the weighted estimate of the representative direction obtained for the at least one reference position.
