Abstract:
In an embodiment, a given entity obtains a location of at least one terrestrial transmit station of a Synchronized Wireless Transmission Network (SWTN), transmit station calibration information associated with the at least one terrestrial transmit station and a location of a user equipment (UE) that is in wireless communication range with the at least one terrestrial transmit station. The given entity estimates the time calibration value for the UE based on the obtained transmit station location, the determined transmit station calibration information and the determined location of the UE. In another embodiment, a server obtains time calibration values that are estimated for each UE in the population of UEs. The server aggregates the estimated time calibration values based on device model and/or device operation mode, and calculates a representative time calibration value for UEs sharing the device model and/or device operation mode.

Abstract:
A method, in a mobile device, of controlling region determination by the mobile device, includes: determining a present pressure at the mobile device; determining, based on the present pressure and a reference pressure, that the mobile device moved from a first region to a second region within a structure, the first region and the second region being different regions of the structure and vertically displaced from each other; and performing region determination in response to determining that the mobile device moved from the first region to the second region.
Abstract:
A method of determining a location of a measurement device includes determining, at a server: measurement times of first positioning signal measurements, of first positioning signals from first positioning signal sources and/or a subset of positioning signal sources of second positioning signal sources. The method includes sending at least one measurement command from the server to the measurement device to cause the measurement device to obtain the first positioning signal measurements in accordance with the measurement times and/or obtain second positioning signal measurements of second positioning signals sent from the subset of positioning signal sources. The method includes: receiving, at the server from the measurement device, measurement data corresponding to the first positioning signal measurements and/or the second positioning signal measurements; and determining, at the server, the location of the measurement device based on the measurement data.
Abstract:
An Real-Time Kinematic (RTK) and/or Differential GNSS (DGNSS) system is disclosed in which correction data from a plurality of reference stations is provided to the mobile device. A selection of reference stations (from which correction data is provided to the mobile device) can be made based on factors such as the approximate location of the mobile device, geometry of the reference stations, and/or other factors. The mobile device can combine the correction data from the plurality of reference stations in different ways to determine an accurate position fix for the mobile device, without interpolating correction data from the plurality of reference stations.
Abstract:
Systems and techniques are provided for determining positioning. For example, the systems and techniques can include obtaining an inertial height measurement, wherein the inertial height measurement is obtained based on a determination that one or more positioning signals are unavailable. A height constraint can be generated using the inertial height measurement, wherein the height constraint is generated based at least in part on a transition matrix. One or more positioning measurements can be determined based on using the height constraint as a real-time kinematic (RTK) positioning input.
