Publication number: 20240053170Abstract: In an aspect, a user device or a server may obtain a global navigation satellite system (GNSS) position of the user device, a sensor-based trajectory of the user device, or both. The user device or the server may filter map data indicating possible routes of the user device based on one or more criteria associated with the GNSS position, the sensor-based trajectory, or both to obtain filtered map data. The user device or the server may determine a position estimate for the user device based on the filtered map data.Type: ApplicationFiled: June 7, 2023Publication date: February 15, 2024Inventors: Gautam NIRULA, Himanshu SHAH, William MORRISON, Hsiao Chien LIANG

Publication number: 20240027227Abstract: Aspects presented herein may improve the performance of positioning devices by enabling the positioning devices to utilize transformed map data with limited third party knowledge of the transformation. Aspects presented herein may enable a positioning device to make the map data from another coordinate system usable for positioning algorithms without knowledge of the transformation. In one aspect, a UE transmits a request for map data based on a first set of coordinates in a first coordinate system. The UE receives the map data based on a second set of coordinates in a second coordinate system, where the first set of coordinates in the first coordinate system is distinct from the second set of coordinates in the second coordinate system. The UE calculates a set of relative distances between the second set of coordinates and one or more objects corresponding to the map data.Type: ApplicationFiled: July 21, 2022Publication date: January 25, 2024Inventors: Himanshu SHAH, Gautam NIRULA, Hsiao Chien LIANG, William MORRISON

Patent number: 11812336Abstract: Techniques for improved GNSS positioning include leveraging approximate location information and information from sensors of a mobile device, and/or sensors communicatively coupled therewith, to detect obstructions and determine which SVs may be blocked from direct view. In particular, information from one or more cameras, LIDAR, radar, and/or other sensor systems can be used to determine how nearby obstructions may block the view of portions of the sky from the perspective of the mobile device, then compared with a SkyPlot of SVs based on the mobile device's approximate location to determine which SVs are likely blocked from view. A GNSS position determination of the mobile device can then be made by reducing the weight of information received from blocked (obstructed) SVs.Type: GrantFiled: October 29, 2019Date of Patent: November 7, 2023Assignee: QUALCOMM IncorporatedInventors: Gautam Nirula, Amol Kench

Patent number: 11809639Abstract: Aspects presented herein may enable an electronic device to determine gyroscope biases and calibrate a gyroscope without a magnetometer or without relying on data generated from a magnetometer. In one aspect, an apparatus estimates a set of gyroscopic biases for a plurality of temperatures or temperature ranges to create a mapping that maps the plurality of temperatures or temperature ranges to the set of gyroscopic biases. The apparatus monitors temperatures of a gyroscope via a gyroscope temperature sensor. The apparatus calibrates the gyroscope in response to the gyroscope changing from a first temperature to a second temperature based on the mapping or based on a predicted value derived from the mapping. In some aspects, the apparatus calculates a DR trajectory of the apparatus based at least in part on the calibrated gyroscope and the accelerometer without using a magnetometer or without using data generated from the magnetometer.Type: GrantFiled: September 29, 2021Date of Patent: November 7, 2023Assignee: QUALCOMM IncorporatedInventors: William Morrison, Hsiao Chien Liang, Gautam Nirula, Himanshu Shah
