Abstract
A method for calibrating an altimeter is disclosed. The method comprises monitoring signal strength of one or more altitude measurements. Based on the signal strength, the method applies piecewise linear altitude correction to the one or more altitude measurements to generate altitude correction data. The method further determines a goodness-of-fit for the altitude correction data. The altitude correction data maintains a correct altitude measurement in the presence of variable signal strength.
