Coning corrections
WebAbstract: A new attitude updating algorithm is designed which considers the high-order terms of the rotation vector. A novel rotation vector calculating structure is proposed, in which the second-order coning correction is calculated using a downsumming structure at a fast updating rate, while the third-order and the fourth-order coning corrections are … WebJan 5, 2024 · This paper investigates the propagation of estimation errors through a common coning, sculling, and scrolling architecture used in modern day inertial …
