A method includes obtaining a benchmark of an accuracy of at least one of a direct positioning technique or an indirect positioning technique for positioning of a mobile device. The method also includes, depending on the benchmark, selecting between positioning of the mobile device using the direct positioning technique and the indirect positioning technique.

Methods and apparatus for verifying respective positions of Nodes based upon wireless communications between Nodes included in an array. Values for variables derived from multiple wireless transmissions between Nodes are aggregated, and a position of a particular Node may be determined based upon multiple data sets generated by multiple communications between disparate Nodes. In addition, the presence of an obstacle to wireless communication between some Nodes may be derived from the data sets. A user interface may provide a pictorial view of positions of all or some Nodes in an array, as well as a perceived obstruction.

Systems, methods, devices, computer readable media, and other various embodiments are described for location management processes in wearable electronic devices. Performance of such devices is improved with reduced time to first fix of location operations in conjunction with low-power operations. In one embodiment, low-power circuitry manages high-speed circuitry and location circuitry to provide location assistance data from the high-speed circuitry to the low-power circuitry automatically on initiation of location fix operations as the high-speed circuitry and location circuitry are booted from low-power states. In some embodiments, the high-speed circuitry is returned to a low-power state prior to completion of a location fix and after capture of content associated with initiation of the location fix. In some embodiments, high-speed circuitry is booted after completion of a location fix to update location data associated with content.

Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile device to determine its location. Techniques are provided which may be implemented using various methods and/or apparatuses on a mobile device to enable location determination during paging slots, wherein location is determined after both a location determination interval and the succeeding paging slot interval are complete. Determined location is stored and may be provided in response to requests from applications, application servers, location servers and for other purposes or entities.

In some examples, a plurality of instances of position data and associated accuracy metadata are acquired by a position sensor. A position of a device comprising the position sensor is determined based on combining the plurality of instances of the position data and the associated accuracy metadata.

Inter-alia, a method is disclosed comprising: obtaining one or more first fallback objects indicative of a geographic area that is covered by one or more cells of a communication network; obtaining one or more pieces of cell information indicative of a number of positioning requests that a respective cell of the one or more cells has received; determining one or more second fallback objects out of the one or more fallback objects; determining for an area of the respective second fallback object in that the needed level of accuracy for determining a position is not achievable, one or more cells based at least partially on the one or more pieces of cell information; and outputting the determined one or more second fallback objects and/or the determined one or more cells for usage in a generation of a radio map. It is further disclosed an according apparatus, computer program and system.

A system and method for detection of an aerial drone in an environment includes a baseline of geo-mapped sensor data in a temporal and location indexed database formed by (i) using at least one sensor to receive signals from the environment and converting into digital signals for further processing; (ii) deriving time delays, object signatures, Doppler shifts, reflectivity, and/or optical characteristics from the received signals; (iii) geo-mapping the environment using GNSS and the sensor data; and (iv) logging sensor data over a time interval, for example 24 hours to 7 days. Live sensor data can be then be monitored and signature data can be derived by computing at least one parameter such as direction and signal strength. The live data is continuously or periodically compared to the baseline data to identify a variance, if any, which may be indicative of a detection event.

A vehicle may determine a predefined communication scheme for localizing a user via time of flight (ToF), responsive to a request designated for fulfilment upon condition that a user is within a certain distance of a vehicle. The vehicle may identify a first user location via a first ToF localization using the predefined communication scheme and a second user location via time of flight using a lower power communication scheme, the lower power communication scene configured to use less power for user localization from a power source as compared to the predefined communication scheme. The vehicle may then, responsive to a difference between the first user location and the second user location being within a predefined threshold difference, save coordinate information indicative of a location of the request as being as suitable for use of the lower power communication.
