Abstract: An example method of position information authentication for a location application performed by a UE, the method comprising determining by a position engine, a position estimate of the UE and determining by the position engine, a position report message indicating the position estimate. The method also comprises determining by a security module, a digital signature generated using a first private key known to the UE and the position report message. The method further comprises transmitting the position report message associated with the digital signature to a location application executed by the UE or another device, wherein the location application is configured to provide one or more location-based services to the UE using the position estimate responsive to a successful authentication of the position report message using the digital signature generated based on the first private key.

Abstract: Techniques are provided for integrating GNSS measurements between two or more GNSS receivers. An example method includes determining an antenna baseline vector based on relative locations of a first antenna that is communicatively coupled to a first GNSS receiver and a second antenna that is communicatively coupled to a second GNSS receiver, determining a first position estimate and a first integer ambiguity resolution (IAR) status with the first GNSS receiver at a first time, determining a second position estimate and a second IAR status with the second GNSS receiver at approximately the first time, computing a horizontal offset value based on the antenna baseline vector and a difference between the first position estimate and the second position estimate, and generating the wrong fix indication in response to the first IAR status being fixed, the second IAR status being fixed, and the horizontal offset value being greater than a threshold value.

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 integer ambiguity resolution method includes: receiving SPS signals; determining, for the SPS signals, candidate float ambiguity values indicative of float numbers of carrier signal wavelengths of the SPS signals between respective satellite sources, of the SPS signals, and the mobile device; and performing, in response to failure of an integer ambiguity resolution validation check based on at least a first subset of the candidate float ambiguity values, an integer ambiguity search using at least a second subset of the candidate float ambiguity values; wherein each candidate float ambiguity value of the at least second subset of the candidate float ambiguity values corresponds to a second indication of candidate float ambiguity accuracy that is higher than a first indication of candidate float ambiguity accuracy, if any, corresponding to the at least first subset of the candidate float ambiguity values.

Abstract: An example method performed at a mobile device for determining a position may comprise receiving correction data associated with (1) a first pseudorange measurement of a first GNSS signal sent from a satellite vehicle on a first GNSS carrier frequency and (2) a second pseudorange measurement of a second GNSS signal sent from the satellite vehicle on a second GNSS carrier frequency. The method also may comprise measuring a third GNSS signal sent from the satellite vehicle and received at the mobile device on a third GNSS carrier frequency, to generate a third pseudorange measurement. The method also may comprise determining the position of the mobile device using (a) the third pseudorange measurement of the third GNSS signal on the third GNSS carrier frequency and (b) the correction data associated with the first pseudorange measurement and the second pseudorange measurement.

Abstract: Aspects presented herein may improve the performance and accuracy of RF-based positioning. Aspects presented herein may enable a device to use RF Doppler measurements to detect and mitigate multipath effects in RF-based positioning. The RF-based positioning may include satellite navigation, terrestrial positioning system, and/or indoor positioning. In one aspect, a UE receives, via a receiver, signals from one or more entities. The UE determines whether each received signal is a multipath signal based on a Doppler shift measurement. The UE de-weights or excludes one or more signals of the received signals in estimating a position of the UE based on whether the respective received signal is determined to be a multipath signal.

Abstract: Embodiments described herein provide for enabling a mobile device comprising a GNSS receiver to implement a modified PPP technique that utilizes orbit and clock information of a satellite that is broadcast from the satellite. In particular, embodiments may utilize a positioning engine to perform PPP error mitigation with respect to various error sources (e.g., troposphere, ionosphere, phase windup, etc.). With regard to errors stemming from satellite orbit and satellite clock, embodiments may utilize orbit and clock information from broadcast ephemeris data rather than obtaining precise orbit and clock information (e.g., from a third party provider). Further, embodiments may account for errors in this broadcast information by adjusting the ambiguity dynamic and/or ambiguity estimate term used by the positioning engine. This can enable the positioning engine to determine a solution more accurate than traditional GNSS without resetting.
