    Abstract: Methods and apparatus to provide assistance data for satellite navigation in a wireless communication device are disclosed. Processing circuitry in the wireless communication device determines whether to obtain assistance data for navigation based on a set of criteria. The set of criteria include one or more of a property of a geographic region in which the wireless communication device operates, a satellite signal quality estimate measured by the wireless communication device, and a user setting of the wireless communication device. When the set of criteria indicates that assistance data for navigation is beneficial for satellite navigation in the wireless communication device, the processing circuitry obtains one or more sets of assistance data. The processing circuitry configures operation of the wireless communication device for navigation based at least in part on the one or more sets of assistance data obtained.

    Abstract: Methods and apparatuses to assist a global positioning system (GPS) module to determine GPS position estimates for a wireless communication device is disclosed. Processing circuitry in the wireless communication device determines a potential or an actual inaccuracy in a GPS position estimate obtained from a GPS module. The processing circuitry obtains a set of map vector data stored in or associated with the wireless communication device. The processing circuitry determines a location estimate of the wireless communication device based on at least a portion of the set of map vector data. The processing circuitry provides the location estimate to the GPS module and obtains an updated GPS position estimate from the GPS module, the updated GPS position estimate based at least in part on the location estimate provided to the GPS module.

    Abstract: An electronic device may include a pressure sensor for measuring barometric pressure. Pressure measurements may be calibrated using crowd-sourced pressure data to remove any weather bias or sensor bias associated with the pressure measurements. Altitude of the electronic device may be determined using the calibrated pressure measurement. When it is desired to estimate altitude, the electronic device may transmit a query to a server, which returns a local reference pressure value for the electronic device based on crowd-sourced pressure data from electronic devices in the vicinity of the electronic device making the query. To determine the local reference pressure value, the server may correlate the crowd-sourced pressure data with space, taking into account variations in terrain using digital elevation models to determine location-specific reference pressures. The local reference pressure value for a given electronic device is then determined using crowd-sourced reference pressures at nearby locations.

    Abstract: A method for identifying a location of a mobile device is disclosed. The method includes during each of a plurality of instances of time: measuring one or more signal properties of one or more other devices across a time interval; obtaining an identifier from each of the one or more other devices; creating a data point to include the one or more signal properties; and storing the data point in a database. The method further includes analyzing the plurality data points in the database to determine clusters of data points; detecting an event at an input device of the mobile device; measuring one or more new signal properties of one or more of the plurality of other devices at one or more new times; creating a new data point from the one or more new signal properties; and identifying a first cluster corresponding to the new data point.
