Book
Optimal Estimation of Dynamic Systems
TL;DR: In this paper, Kronecker Factorization and Levenberg-Marquardt method for least square estimation is used to estimate the probability of an error in a prior state estimate.
Journal ArticleDOI
Survey of nonlinear attitude estimation methods
TL;DR: A survey of modern nonlinear filtering methods for attitude estimation based on the Gaussian assumption that the probability density function is adequately specified by its mean and covariance is provided.
Journal ArticleDOI
Unscented Filtering for Spacecraft Attitude Estimation
TL;DR: In this paper, an unscented filter is used to estimate the attitude of a spacecraft in the presence of a gyro-based model for attitude propagation, and a multiplicative quaternion-error is derived from the local attitude error, which guarantees that quaternions normalization is maintained in the filter.
Book ChapterDOI
Sensors and Actuators
TL;DR: The history of attitude sensor development has emphasized increased resolution and accuracy as well as decreased size, weight, and power (often abbreviated as SWaP).
Book
Fundamentals of Spacecraft Attitude Determination and Control
TL;DR: In this article, the authors present a static method for determining the attitude of an individual in relation to an object, using a combination of static and dynamic methods. But they do not specify the parameters of the static method.
