An altimeter is an instrument used to measure altitude, sometimes above sea stage. Altimeters are utilized in navigation, aviation, climbing, and different actions the place understanding the altitude is vital.
There are two principal forms of altimeters: barometric altimeters and GPS altimeters. Barometric altimeters measure the air stress and use the connection between air stress and altitude to calculate the altitude. GPS altimeters use the World Positioning System (GPS) to find out the altitude.
