An altimeter is an instrument used to measure altitude, sometimes above sea degree. Altimeters are utilized in navigation, aviation, mountaineering, and different actions the place understanding the altitude is necessary.
There are two essential sorts of altimeters: barometric altimeters and GPS altimeters. Barometric altimeters measure the air strain and use the connection between air strain and altitude to calculate the altitude. GPS altimeters use the International Positioning System (GPS) to find out the altitude.
