Extending spatial coverage of reference pressure network for altitude estimation
A recently granted patent (Publication Number: US11913809B2) outlines a method for extending the spatial coverage of a network of reference pressure sensors for mobile devices. The method involves determining the reference-level pressure for the estimated position of a mobile device by utilizing a set of reference-level pressures and a pressure pattern for the region. This information is then used to calibrate the pressure sensor of the mobile device. The patent also includes provisions for determining the altitude of the mobile device for emergency response or navigation purposes based on the reference-level pressure value.
Furthermore, the patent details a processing system that includes a memory with computer-executable instructions and a machine to execute these instructions. This system is designed to implement the method described in the patent for extending the spatial coverage of the reference pressure network. By utilizing a combination of reference-level pressures and pressure patterns, the method aims to enhance the accuracy and reliability of pressure sensor calibration and altitude estimation for mobile devices operating outside the coverage area of the network of reference pressure sensors. This innovation could have significant implications for improving location-based services and emergency response systems that rely on accurate altitude information.
