How does a weather satellite altimeter work
As the name implies, radar (radio detection and ranging) is the underpinning principle of the system. The system transmits radio waves down to the ground and measures the time it takes them to be reflected back up to the aircraft. The altitude above the ground is calculated from the radio waves' travel time and the speed of light. Radar altimeters required a simple system for measuring the time-of-flight that could be displayed using conventional instruments, as oppose… WebNov 12, 2024 · How Does An Altimeter Work? Altimeters determine the altitude based on the atmospheric pressure and they use the instrument “Barometer” to do it. This instrument determines the atmospheric pressure and then uses that reading to determine the Altitude. ... Bad weather can affect the functionality of the Altimeter. The basic Altimeters are ...

As altitude goes up, the pressure decreases. If I take a barometric altimeter up to space (e.g. up to satellite orbit), at what altitude does its reading become useless, i.e. the reading can no longer be trusted as a measurement of the height above sea level?
