摘要： A determining method comprises a first computing step implemented by a computational module to compute a static pressure from an altitude determined by a geolocation module, a receiving step implemented by a reception module to receive a static pressure determined by a static pressure sensor, a second computing step implemented by a second computational module to compute a static pressure difference between the static pressure and the static pressure, a step of filtering the static pressure difference, a third computing step implemented by a third computational module in order to compute the backup altitude from the filtered static pressure difference and from the static pressure, and a sending step implemented by a sending module in order to deliver the computed backup altitude to a user device.
