Abstract: Described are methods, systems, and devices for correcting ionospheric error. In some aspects, a mobile device equipped with a Global Navigation Satellite System (GNSS) receiver is configured to determine a positioning measurement of a GNSS signal. The mobile device is further configured to receive augmentation data from an augmentation system. When the mobile device is unable to obtain newer augmentation data, the mobile device can instead obtain augmentation data associated with historical Total Electron Content (TEC) values. In such instances, the augmentation data will have been generated to represent ionospheric delay during a time period that ended before the augmentation data is obtained. Based on the augmentation data associated with historical TEC values and a pierce point of the received GNSS signal, an ionospheric error in the positioning measurement of the GNSS signal can be determined and corrected.

Abstract: A Real-Time Kinematic (RTK) solution is provided to mobile devices having multi-constellation, multi-frequency (MCMF) functionality, in which a single base station may have a baseline much farther than traditional base station and where the high accuracy positioning is achieved in a relatively short period of time. To enable this, embodiments involve modeling of an ionosphere-free carrier phase corresponding to combinations of at least three signals received from one or more satellites. The modeling retains the integer nature of carrier phase ambiguities, thereby allowing for fast convergence in determining the integer ambiguity of the carrier phases.

Abstract: Techniques described herein leverage MCMF functionality to provide a local RTK solution for a mobile device in which an initial highly-accurate location determination for the mobile device can be leveraged to generate RTK correction information that can be used to make subsequent, highly-accurate location determinations without the need for measurement information from an RTK base station. This RTK correction information can be applied to GNSS measurements taken by the mobile device over a long period of time while retaining the ability to produce highly-accurate location determinations for the mobile device. And additional correction information may be obtained and applied to the RTK correction information to extend this period of time even longer.

Abstract: A Real-Time Kinematic (RTK) solution is provided to mobile devices having multi-constellation, multi-frequency (MCMF) functionality, in which a single base station may have a baseline much farther than traditional base station. To enable this, embodiments account for differences in atmospheric effects between the rover station and base station when determining a GNSS position fix for a mobile device (rover station), allowing for a separate tropospheric delay error for a base station to be determined. Embodiments may use additional satellite measurements for which no RTK correction is available, and may further use orbital clock correction for these additional satellite measurements.

Abstract: Methods and systems are disclosed for improving reliability in mobile device positioning. A mobile device generates position data for a device, receives a first access point position reliability state associated with the first access point, determines a reliability of the position data based on the first access point position reliability state and an estimated location of the first access point, determines a threshold reliability requirement of an application associated with the mobile device, compares the reliability of the position data to the threshold reliability requirement of the application, and provides the position data of the device based on the comparison. A network entity determines access point characteristics associated with an access point, generates a position reliability state for the access point, sends the position reliability state to a mobile device, receives position data associated with the mobile device, and determines a trustworthiness of the position data.

Abstract: A method of determining a location of a base station includes: receiving, at a mobile device from a location server, a base station identifier (BSID) of the base station and two or more candidate locations of the base station; receiving a signal, at the mobile device from the base station identified by the BSID; and selecting, at the mobile device, a particular candidate location from the two or more candidate locations based on a characteristic determined from the signal. A method of identifying an actual location of a base station includes: transmitting, from a location server to a disambiguating mobile device, a base station identifier (BSID) of the base station and two or more candidate locations of the base station; and receiving, at the location server from the disambiguating mobile device, an indication of the actual location of the base station from among the two or more candidate locations.

Abstract: In a tracking of a position and motion of a device, a set of hypothetical locations of the device is generated. Hypothetical locations among the set are propagated to respective hypothetical next locations, using respective location-specific propagation models associated with the hypothetical locations. Sensor information having correlation to a location of the device is received. An importance weighting for the hypothetical next locations is calculated using the new sensor information. Probable locations of the device are generated using the importance weighting.
