An angular rate sensor with temperature compensation and automatic zero calibration is designed in this paper: by means of the temperature compensation of the single-axis gyroscope realized by MAX1452AAE, we make the single chip micro-computer do the A/D conversion and the power-automatic zero calibration, then transfer the result into measurements using the calibration coefficients of the internal storage and finish the output through the RS422 interface. Tests prove that the sensor out-put precision and the zero stability are improved obviously after calibration.
