Abstract: A method being for facilitating positioning determination of a UE includes: obtaining motion information indicative of motion of the UE; obtaining positioning information based on positioning signals received by the UE; determining a validity status of map data based on whether the positioning information, the motion of the UE, and the map data, that include locations of physical environmental features, are consistent, wherein the validity status is determined to be valid in response to the positioning information, the motion of the UE, and the map data being consistent; and determining at least one of a position estimate for the UE, or a direction of motion of the UE, based on the map data and based on the validity status being valid.

Abstract: Techniques for providing positioning information to a mobile device are discussed. An example apparatus for determining a location of a mobile device includes at least one server comprising a data structure containing precise positioning subscription options associated with the mobile device, a plurality of client internet of things devices configured to communicate with the at least one server, such that at least one of the plurality of client internet of things devices is a serving internet of things device configured to provide precise positioning information to the mobile device, and such that the serving internet of things device is selected from the plurality of client internet of things devices based on the precise positioning subscription options.

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: 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 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.
