Abstract: In an aspect, a user equipment (UE) receives a spoofing alert message from either a server or an internet-of-things (IOT) device that indicates whether a spoofed Global Navigation Satellite System (GNSS) condition is present. Based on determining that the spoofing alert message indicates that a spoofed GNSS condition is present, the UE determines, based on the spoofing alert message, a location of a spoofer broadcasting a spoofed GNSS signal, determines, based on the location of the spoofer and a current location of the UE, that the UE is within a receiving area of the spoofed GNSS signal, and determines a position of the UE without using the spoofed GNSS signal.

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: 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: Position, Velocity, and Time (PVT) information of a LEO satellite can be determined by leveraging a known position of a mobile device comprising a terrestrial satellite receiver of the LEO satellite and using range information (range and/or range rate) of the LEO satellite taken at the mobile device. According to some embodiments, this PVT information can be shared by the mobile device with the server and/or other mobile devices, and information from multiple mobile devices can be crowdsourced to determine robust PVT information for a LEO satellite. Once the PVT information is determined, it can be used to subsequently for positioning of the mobile device and/or other mobile devices.

Abstract: A Precise Positioning Engine (PPE) may use correction information to perform highly accurate Global Navigation Satellite Systems (GNSS) positioning. Transitioning between, or “swapping,” of a first correction information source (e.g., Real-Time Kinematic (RTK) base station) with a second correction information source may be handled using correction information from the first correction information source to update a first state of the PPE. The updated PPE can then be modified by initializing at least ambiguity values of the PPE state. Correction information from the second base can be used to further update the PPE to a second state without a time update at the PPE. By employing this process, embodiments can reduce sudden changes in position estimation due to correction information source swapping, which can often result in resetting of the PPE and a reduced user experience quality.
