摘要：

The feasibility of an autonomously aided strapdown attitude reference system, based solely on the measurements of an orthogonal triad of rate gyros and conventional air data, is explored. The aiding is provided by the aerodynamic model of the aircraft and a reduced-order multirate extended Kalman filter (EKF). It is demonstrated that the EKF provides on-line attitude estimates with bounded errors not exceeding 0.5 deg at output rates on the order of 20 Hz. On-line simulation tests, incorporating low-cost rate gyros mounted on a high-precision three-axis flight table, validate the feasibility of the concept.
