Abstract
A new design technology of altimeter of micro air vehicle is introduced.Using micro digital pressure sensor and microcontroller chip PIC to make series communication
the pressure
temperature and compensation parameters from the sensor are read out
compensation of temperature and calculation of height are carried out with the software.The test in the laboratory shows that its error is less than ±3 m.And the altimeter has many merits such as small volume
