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: 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: A multipath condition detection method includes: determining a first signal quality value corresponding to a first wireless signal, of a first frequency and from a signal source, received by a receiver of a mobile device; determining a second signal quality value corresponding to a second wireless signal, of a second frequency that is different from the first frequency, received by the receiver; and determining whether at least one difference value, corresponding to the first signal quality value and the second signal quality value, is indicative of the mobile device being in a multipath condition with respect to the signal source.

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: A positioning method includes: receiving, at an apparatus from a first signal source, a first positioning signal; determining, at the apparatus, a first receiver clock value with respect to the first positioning signal; determining, at the apparatus in response to loss of reception of the first positioning signal, a drift of the first receiver clock value using delta carrier phase updating based on one or more available positioning signals; and determining, at the apparatus, a second receiver clock value based on the first receiver clock value and the drift of the first receiver clock value.

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.

Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a vehicle to determine location relative to a roadside unit (RSU) or other nearby point of reference. Vehicles within a pre-designated range or within broadcast distance or otherwise geographically proximate to a roadside unit, through the use of broadcast or other messages sent by the vehicles and/or the RSU may share carrier GNSS phase measurement data, wherein the shared GNSS carrier phase measurement data may be utilized to control and coordinate vehicle movements, velocity and/or position by the RSU and/or to determine location of each vehicle relative to the RSU and/or to other vehicles or determine the absolute location of each vehicle. An RSU may coordinate vehicle access to an intersection, manage vehicle speeds and coordinate or control vehicle actions such as slowing, stopping, and changing lanes or sending a vehicle to a particular location.
