Altitude measurement in model rockets is typically done using an altimeter, which is a small electronic device that measures the change in air pressure as the rocket ascends. As the rocket climbs, the air pressure decreases, and the altimeter uses this change to calculate the altitude. Some altimeters also have built-in accelerometers to measure the rocket's velocity and can provide additional data such as maximum altitude reached and descent rate. This information is then recorded and can be used for analysis and tracking the performance of the rocket. **
