Gyro calibration is a complex taskm, mainly because of the difficulty of managing angular velocity standards. This is especially true 'in field' and therefore low-cost sensors cannot to be used in high-accuracy applications. This paper presents a calibration process that does not require rotating tables or other velocity standards. The calibration is carried out making reference only to geometrical quantities and using the A/D conversion system and the computing system normally connected to the gyro. The calibration can be completed in a few minutes, and results in a noticeable improvement in accuracy.
