Abstract: A global navigation satellite system (GNSS) device may receive GNSS correction data and may determine a respective standard deviation of pre-fit residuals of one or more GNSS measurement types of a set of GNSS measurements. The GNSS device may determine at least one conditional trigger is met based on a comparison of the respective standard deviation of pre-fit residuals of the one or more GNSS measurement types with a respective threshold, and, responsive to determining the at least one conditional trigger is met, may modify how a positioning engine processes one or more measurements of the set of GNSS measurements. The GNSS device may determine a position estimate of the GNSS device based at least in part on a result of the modified processing of the one or more measurements by the positioning engine and the GNSS correction data.

Abstract: A method for wireless communication at a GNSS is described herein. The method includes obtaining a set of SSR error correction components associated with a set of SVs, where the set of SSR error correction components includes a first number of SSR error correction components that is less than a second number of SSR error correction components in a full set of SSR error correction components. The method includes generating, based on the set of SSR error correction components, (1) an OSR of GNSS measurements associated with the set of SVs and (2) an OSR uncertainty value for the OSR. The method includes computing, based on the OSR of the GNSS measurements and the OSR uncertainty value, a position of the GNSS wireless device. The method includes outputting an indication of the position of the GNSS wireless device.

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: In some implementations, one or more devices may obtain measurement information for an epoch, the measurement information indicative of a pseudorange measurement, a carrier phase measurement, and a doppler measurement performed by a reference global navigation satellite system (GNSS) receiver of radio frequency (RF) signals transmitted by a plurality of GNSS satellites. The device(s) may obtain initial state-space representation (SSR) data comprising orbit correction, clock correction, and code bias information for the epoch. The device(s) may determine ionospheric correction data for the epoch based on the measurement information and the initial SSR data. The device(s) may determine tropospheric correction data for the epoch based on the determined ionospheric correction data, the measurement information, and the initial SSR data. The device(s) may provide the expanded SSR data, wherein the expanded SSR data includes the ionospheric correction data and the tropospheric correction data.

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: A method of determining an integer ambiguity search space includes: obtaining, at an apparatus, a code phase measurement of a satellite vehicle signal comprising a pseudorandom noise code and a carrier signal; obtaining, at the apparatus, spatial information corresponding to a wireless terrestrial signal transferred between the apparatus and a terrestrial base station; determining, at the apparatus, a satellite positioning system carrier phase integer ambiguity search space based on the code phase measurement; and constraining a size of the satellite positioning system carrier phase integer ambiguity search space based on the spatial information.

Abstract: Aspects presented herein may enable a UE to identify whether images captured by the camera(s) of the UE are spoofed (e.g., are real images or false/manipulated/virtual images, etc.). In one aspect, a UE obtains a set of images associated with a vision-aided positioning session, where the set of images is captured using at least one first camera. The UE detects that at least one spoofing feature is present in the set of images during the vision-aided positioning session. The UE stores or outputs an indication of the at least one spoofing feature based on the at least one spoofing feature being present in the set of images. The UE performs the camera-aided positioning session based on at least one non-spoofing feature, where the at least one non-spoofing feature is different from the at least one spoofing feature.

Abstract: A method, for providing a virtual positioning signal measurement, includes: determining that an expected positioning signal measurement is absent from a plurality of actual positioning signal measurements made by a UE; and providing a virtual measurement value, for the expected positioning signal measurement, based on at least one actual positioning signal measurement that is of a same type as the expected positioning signal measurement and that corresponds to at least one positioning signal measured by the UE.

Abstract: Aspects presented herein may enable a navigation application of a UE to feed its calculated navigation route information to a PE of the UE to aid the PE computing positioning estimations to improve positioning accuracy. In one aspect, a UE estimates a current location of the UE based on a set of positioning measurements and time update predictions using a positioning engine. The UE calculates real-time navigation route information using at least one navigation application based on the current location of the UE, a destination of the UE, and map information. The UE changes or verifies a set of positioning estimations performed by the positioning engine based on the real-time navigation route information from the at least one navigation application.
