Abstract: Aspects presented herein may improve the positioning accuracy and latency of a positioning engine that receives at least one position constraint for assisting the positioning. A wireless device obtains an indication of at least one position constraint for a positioning engine. The wireless device detects whether the at least one position constraint exceeds an error threshold based on a set of PR residuals between the wireless device and at least one satellite. The wireless device excludes the at least one position constraint from a calculation at the positioning engine if the at least one position constraint exceeds the error threshold, or includes the at least one position constraint in the calculation at the positioning engine if the at least one position constraint is below the error threshold.

Abstract: The user equipment (UE) of an antenna orientation detection system may receive a first set of beacon signals via an antenna at the UE. Each of the first set of beacon signals may be associated with a corresponding indication of an expected beacon location. The UE may calculate an orientation of the antenna based on the first set of beacon signals. The UE may change at least one of a position, the orientation, or a direction of the antenna and receive a second set of beacon signals. The UE may calculate at least one of a set of interfering condition parameters, a set of spoofing condition parameters, or a set of non-line-of-sight (NLOS) condition parameters based on the first set of beacon signals and the second set of beacon signals.

Abstract: A Precise Point Positioning (PPP) system is disclosed in which one or more Global Navigation Satellite System (GNSS) signals are obtained by a mobile device. The mobile device can obtain position information based on one or more position sources, where the position information is indicative of a location of the mobile device. One or more PPP positions of the mobile device can be determined based on the position information and the one or more GNSS signals, where a position uncertainty of the position information meets or is below an uncertainty threshold. A determination of whether at least one PPP position meets or is below one or more convergence thresholds can be made. In response to determining that at least one PPP position meets or is below the one or more convergence thresholds, the at least one PPP position can be provided.

Abstract: Disclosed are various techniques for wireless communication. In one aspect, a user equipment (UE) may receive, from a satellite vehicle (SV), a signal of a first frequency band, estimate a first ionospheric delay residual error based on the signal of the first frequency band, calculate a first pseudorange measurement and a first carrier phase measurement based on the first ionospheric delay residual error, and estimate a position using the first pseudorange measurement and the first carrier phase measurement. In some aspects, the ionospheric delay residual error is estimated via a Klobuchar equation. In some aspects, the position is estimated using ultra-long baseline real-time kinematics (RTK) positioning.

Abstract: A user equipment (UE) may receive a set of reference signals (RSs) from a set of non-terrestrial network (NTN) nodes. The set of RSs may travel from the set of NTN nodes to the UE through a first portion of an atmosphere and a second portion of the atmosphere. The UE may measure the set of RSs. The UE may calculate, based on the measured set of RSs, a first set of atmospheric delays associated with the first portion of the atmosphere and a second set of atmospheric delays associated with the second portion of the atmosphere. The UE may calculate a location of the UE based on the measured set of RSs, the first set of atmospheric delays, and the second set of atmospheric delays. The UE may transmit the calculated location of the UE. The first portion may include an ionosphere. The second portion may include a troposphere.

Abstract: An example method for updating GNSS error correction data for global navigation satellite system (GNSS)-based positioning. The method performed by a server may comprise obtaining multiple GNSS measurements crowdsourced from one or more GNSS devices across a plurality of measurement epochs, determining GNSS measurement residuals using the multiple GNSS measurements and existing GNSS error correction data, and sending updated GNSS error correction data for GNSS-based positioning, wherein the updated GNSS error correction data is determined using the determined GNSS measurement residuals and the existing GNSS error correction data.

Abstract: Techniques for global navigation satellite system (GNSS)-based positioning of a mobile device based on antenna phase center compensation are disclosed. The techniques can include determining a phase center profile of a receiver antenna of the mobile device that is placed in a fixed-frame condition and executing an antenna phase center compensation procedure upon detecting placement of the mobile device in a non-fixed frame condition. The antenna phase center compensation procedure can include obtaining attitude information of the mobile device based at least in part on sensor data obtained from one or more sensors of the mobile device, and incorporating the attitude information of the mobile device into the phase center profile of the receiver antenna of the mobile device. A global navigation satellite system-based positioning operation may be executed that includes antenna phase center compensation based at least in part on incorporating the attitude information into the phase center profile.

Abstract: Aspects presented herein may improve/enhance camera-aided/assisted positioning by utilizing light and shadow created by an artificial light. In one aspect, a UE captures a set of images of an object using at least one camera. The UE estimates a direction of at least one light source based on a shadow of the object in the set of images, wherein the shadow of the object is created by the at least one light source. The UE calculates at least one of (1) a distance (d) between the at least one camera and a set of first features associated with the object based on the estimated direction of the at least one light source or (2) directional information of a set of second features associated with a surrounding environment that is within a threshold distance of the object.
