Abstract

Method (50) for determining a first (P₁') and a second (P₂') calibrated value of atmospheric pressure, performed by an electronic apparatus (10) comprising a fixed device (14) and a first (12a) and a second (12b) movable device comprising respectively a first (16a) and a second (16b) movable barometer. The method (50) comprises: determining (S10) whether the movable devices are being inductively charged by the fixed device; if so, acquiring (S12) respective measured values of atmospheric pressure (P₁, P₂) through the movable barometers (16a, 16b), and a reference value of atmospheric pressure (P_rif) in a common reference point of the electronic apparatus (10), the movable barometers being at respective predefined height differences (Δh) with respect to the common reference point; calculating (S14) respective pressure differences (ΔP₁, ΔP₂) as a function of the measured values of atmospheric pressure and of the reference value of atmospheric pressure; and when the movable devices are not being charged, acquiring (S20) new measured values of atmospheric pressure through the movable barometers, and determining (S20) the respective calibrated values of atmospheric pressure as a function of the new measured values of atmospheric pressure and of the pressure differences.
