How Barometric Altimeters Measure Elevation
A barometric altimeter measures elevation by detecting changes in atmospheric pressure, which correlates with altitude. As elevation increases, atmospheric pressure decreases predictably, providing a basis for altitude estimation. An altimeter contains a sealed chamber with a flexible diaphragm that responds to pressure variations. When outside atmospheric pressure changes, the diaphragm moves accordingly, translating these movements into a measurable mechanical or electronic signal. This signal is then calibrated to indicate altitude. In military land navigation, understanding how barometric altimeters measure elevation allows operators to determine their position accurately when combined with other navigational methods.
