Abstract
An apparatus for determining an altitude of a mobile unit includes one or more processors individually or collectively configured to obtain local measurement data comprising a local atmospheric pressure at a location of the mobile unit, obtain reference measurement data comprising a reference atmospheric pressure at a location of a reference unit that is movable, and determine the altitude of the mobile unit based on the local measurement data and the reference measurement data.
