Abstract
The present invention relates to a method for calibration of a gyro sensor which controls the attitude of a device such as an antenna by detecting acceleration with respect to three axis directions and, more particularly, to a method for calibration of a gyro sensor, in which the calibration of the gyro sensor is performed by interworking with a tilt sensor. In particular, it is possible to calibrate the gyro sensor, which detects rotation with respect to a Z-axis by standing a sensor board provided with a sensor, by interworking with a tilt sensor.
Claims4
A method of calibrating three gyro sensors included in a sensor board attached and installed to a target object and configured to respectively detect angular velocity with respect to X-axis, Y-axis, and Z-axis directions based on the sensor board, using a tilt sensor included in the sensor board and configured to detect a tilt with respect to gravity, the method comprising:
- a) supplying power to a driver for driving the target object (S100);
- b) maintaining the sensor board in a horizontal state with respect to the ground by the tilt sensor (S200);
- c) determining whether the target object is moved (S300);
- and
- d) when there is a motion (S300-Y), applying an output value of the tilt sensor to calibrate the gyro sensor.
