Abstract: A device includes global positioning circuitry, sensing circuitry, and processing circuitry. The global positioning circuitry, in operation, receives location-related data. The sensing circuitry, in operation, senses data related to the device. The processing circuitry, in operation, determines a motion state of the electronic system based on data sensed by the sensing circuitry, and selects a plurality of control parameters from one or more configuration matrixes based on the determined motion state. The plurality of control parameters includes a power-mode control parameter and a location-determination control parameter. The processing circuitry configures a power-mode of the device based on the power-mode control parameter, and determines a location characteristic of the device based on the received location-related data and the location-determination control parameter.

Abstract: A method performs a correction of an ionospheric error affecting pseudo-ranges measurements in a GNSS receiver receiving a plurality of satellite signals from a plurality of satellites of a constellation of satellites. The method is part of a navigation processing procedure performed at the GNSS receiver. The method utilizes pseudo range measurements previously calculated by the GNSS receiver, obtained from a plurality of carrier signals in the satellite signals. The method includes performing a correction procedure of the pseudo-range measurements, by calculating ionospheric error correction values for the pseudo-range measurements.
