After theoretical analysis and trial and error, a linear regression model of barometric altimeter pressure error and temperature and voltage change rate was put forward, and the parameters of barometric altimeter error model were obtained through model test. The rate of temperature and voltage change was tracked in real time and the barometric altimeter was automatically corrected in real time After several verifications, the accuracy of the altimeter is increased by about 60%, which improves the adaptability of the barometer under the conditions of warm and changeable environment and further widens the application field of the barometer. The error compensation The technology is versatile in the field of barometric altimeters and is simple and easy to implement for engineering applications.
