Abstract The Generalized Wahba Problem, which can accept as input both measured
directions and measured attitudes, is defined and examined in terms of both the attitude …

A detailed study is undertaken of the accuracy and robustness of solutions to the Wahba
problem, the starting point for most modern estimators of three-axis attitude. The importance …

The TRIAD algorithm is shown to be derivable as a maximum-likelihood estimator. In
particular, using the QUEST measurement model, the TRIAD attitude error covariance matrix …

In this paper, a nonlinear adaptive backstepping Lyapunov-based controller is designed for
spacecraft. Using the Lyapunov theory, the integrated adaptive backstepping controller …
