Publication number: 20240385066Abstract: Described herein are techniques to enable a mobile device to perform multi-source estimation of an altitude for a location. A baseline altitude may be determined at ground level for a location and used to calibrate a barometric pressure sensor on the mobile device. The calibrated barometric pressure sensor can then estimate changes in altitude relative to ground level based on detected pressure differentials, allowing a relative altitude to ground to be determined. Baseline calibration for the barometric sensor calibration can be performed to determine an ambient ground-level barometric pressure.Type: ApplicationFiled: July 22, 2024Publication date: November 21, 2024Inventors: Lei Wang, William J. Bencze, Kumar Gaurav Chhokra, Fatemeh Ghafoori, Stephen P. Jackson, Cheng Jia, Yi-Wen Liao, Glenn D. Macgougan, Isaac T. Miller, Alexandru Popovici, Christina Selle, Aditya Narain Srivastava, Richard Warren, Michael P. Dal Santo, Pejman Lotfali Kazemi
