An altimeter is an instrument that is used to measure the altitude of an aircraft or other aerospace system. Altimeters work by measuring the pressure of the air at the altitude at which the aircraft or other system is flying.
The pressure of the air decreases with increasing altitude, so by measuring the pressure, the altimeter can determine the altitude of the aircraft or other system. Altimeters are an important part of the navigation and control systems of aircraft and other aerospace systems, as they provide information on the altitude of the system and help to ensure that it is flying at the correct altitude. Altimeters are used in a variety of aerospace applications, including aviation, spaceflight, and high-altitude ballooning.
Altimeters are also used on satellites and rockets. Satellites and rockets operate at very high altitudes, and altimeters are used to measure the altitude of these systems in order to determine their position and to help control their flight. Altimeters can be used on satellites and rockets for a variety of purposes, including the measurement of atmospheric parameters, the determination of the position and orientation of the satellite or rocket, and the control of the flight path. Altimeters used on satellites and rockets may be designed to operate in the vacuum of space and may be equipped with sensors and other equipment that are specifically designed for use in space.
