 Description: The attitude information is one of the most important parameters in flight control systems. This paper describes an attitude measurement system based on a MEMS multi-sensor. The data from 3-axis MEMS accelerators and 3-axis MEMS gyros is used to determine the pitch angle and the roll angle of the air vehicle using an extended Kalman filter (EKF) equation deduced from the direction cosine matrix. An expert system was designed to estimate the vehicle motion to adjust the measurement noise matrix of the extended Kalman filter equation so that the system can be used in dynamic as well as static environments. The measured airspeed and altitude are also used to revise the pitch angle. The heading is determined from GPS information. Test results compare well with an imported commercial autopilot in a static test with less accurate results in a dynamic test.
