Abstract： |
The invention discloses a method and system of measuring carrier attitude, which comprises data processing device and sensor composed of three axis accelerometer, three axis flux meter, three axis rate gyroscope for measuring acceleration of gravity, earth magnetic flux density, the component of the carrier¡¯s angular speed on the coordinate system individually. When processing the signal, use the component of the carrier¡¯s angular speed to Kalman filtering the measured acceleration of gravity and earth magnetic flux density and get the estimated value by which resolve the carrier attitude. The invention can reduce the impact of the system causing by acceleration through stabilizing gyroscope signal and do not have the problem of integral float, the sensor using MEMS integrated chip technology. |
