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.

A wireless computing device may scan a frequency set. A first group of base stations may use the frequencies in the frequency set. Based on information relating to one or more base stations in the first group of base stations, the wireless computing device may estimate its location. The wireless computing device may further select a frequency subset of the frequency set. A second group of base stations may use the frequencies of the frequency subset. Based on information relating to one or more base stations in the second group of base stations, the wireless computing device may again estimate its location. If the two estimated locations are within a threshold distance of one another, the wireless computing device may perform, during a subsequent location-estimating operation, an additional frequency scan using the frequency subset.

Examples describe methods, computing devices, and systems for using location provider (LP) processes to accurately identify a proximate location of a computing device, while reducing the power consumption of the computing device. An example method may include executing, on a computing device, both a first LP process and a second LP process simultaneously for at least part of a time period to determine outputs indicative of locations of the computing device for the time period. Further, the method may include determining a motion model of the computing device that indicates expected locations of the computing device. Yet further, the method may include making a comparison of the outputs to the motion model for the time period. In addition, the method may include disabling one of the LP processes based on the comparison.

A mobile application tracks a user's behavior and activities and, in particular, a geo-location. The mobile application may then produce a profile of the user's behaviors and locations. This may be used to optimize mobile device power and may also be used as a data aggregator to collect and gather user information for other purposes, such as data marketing and modeling. In an embodiment, the mobile application is continuously monitoring the mobile device's battery level and power usage and determining the most power-efficient approach for tracking the device's location. One-hundred percent location accuracy is not always required when profiling a user's behavior. It may be more critical to simply determine the general location of the device and the associated user. The application may continuously function in the background while expending the least amount of power possible.

Systems and methods for improved geolocation in a low power wide area network are disclosed. One example method may include receiving an instruction to determine a geolocation of an end in a low power wide area network. An instruction may be transmitted to the end node for the end node to transmit a high-energy geolocation signal at a power of about 0.5 Watt to about 1 Watt. The end node may transmit the high-energy geolocation signal and a plurality of gateways of the low power wide area network may receive the high-energy geolocation signal. A plurality of receipt times may be identified. Each receipt time may be indicative of the time at which the high-energy geolocation signal was received by the respective gateway of the plurality of gateways. Based at least in part on the plurality of receipt times, a geolocation of the end node may be determined.

A positioning method and apparatus for a mobile terminal, and a mobile terminal. After a first time period elapses, a main processor obtains M pieces of reliable navigation data from N pieces of buffered navigation data of the mobile terminal, and obtains K pieces of buffered position change data of the mobile terminal. The main processor combines the M pieces of reliable navigation data and the K pieces of position change data, to obtain position information of the mobile terminal in the first time period. The N pieces of navigation data are obtained through calculation by using a satellite navigation signal of the mobile terminal that is received during the first time period. The K pieces of position change data are obtained through calculation by using data that is obtained through monitoring by a sensor of the mobile terminal during the first time period.

Methods and apparatus for verifying respective positions of Nodes based upon ultrawideband wireless communications between nodes included in an array. Values for variables derived from multiple wireless transmissions between the nodes are aggregated, and a position of a particular node may be determined based upon multiple data sets generated by multiple communications of disparate Nodes. Data is transmitted to a smart device based upon a position of a particular node and a direction of interest. 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.

The present invention relates to a multimodal sensing positioning system orientated to a high-risk production environment, the positioning system comprising: at least one positioning terminal, configured to be worn by a to-be-positioned subject and use at least one positioning technique to conduct multimodal sensing positioning so as to identify a current location information of the subject in the high-risk production environment; and a monitoring terminal, communicating with the positioning terminal so as to remotely monitor the current location of the subject. The present invention improves positioning precision while ensuring realtimeness of multimodal positioning.
