ABSTRACT:
An apparatus and method of measuring elevation of vehicles, such as radiodes, aircraft, or re-entry vehicles, is provided by identifying the specific geographic location of the vehicle in question and its difference from the geographic location of a reference station. The reference station altitude is then used as an arbitrary level to measure difference in elevation of the vehicle in question.
