摘要：

A new algorithm is proposed that smoothly incorporates the nonlinear estimation of the attitude quaternion using Davenport's q-method and the estimation of nonattitude states through an extended Kalman filter. The new algorithm is compared to an existing one and the various similarities and differences are discussed. The validity of the proposed approach is confirmed by numerical simulations.
