Propagation of Uncertainty in Rigid Body Attitude Flows [PDF]

arXiv, 2007
Motivated by attitude control and attitude estimation problems for a rigid body, computational methods are proposed to propagate uncertainties in the angular velocity and the attitude. The nonlinear attitude flow is determined by Euler-Poincar\'e equations that describe the rotational dynamics of the rigid body acting under the influence of an attitude

Attitude Determination and Estimation using Vector Observations: Review, Challenges and Comparative Results [PDF]

arXiv, 2020
This paper concerns the problem of attitude determination and estimation. The early applications considered algebraic methods of attitude determination. Attitude determination algorithms were supplanted by the Gaussian attitude estimation filters (which continue to be widely used in commercial applications).

Global Attitude Estimation using Single Direction Measurements [PDF]

arXiv, 2006
A deterministic attitude estimator for a rigid body under an attitude dependent potential is studied. This estimator requires only a single direction measurement to a known reference point at each measurement instant. The measurement cannot completely determine the attitude, but an attitude estimation scheme based on this measurement is developed; a ...

Geometric Tracking Control of the Attitude Dynamics of a Rigid Body on SO(3) [PDF]

arXiv, 2010
This paper provides new results for a tracking control of the attitude dynamics of a rigid body. Both of the attitude dynamics and the proposed control system are globally expressed on the special orthogonal group, to avoid complexities and ambiguities associated with other attitude representations such as Euler angles or quaternions.

Semi-Analytic Method for SINS Attitude and Parameters Online Estimation [PDF]

arXiv, 2018
In this note, the attitude and inertial sensors drift biases estimation for Strapdown inertial navigation system is investigated. A semi-analytic method is proposed, which contains two interlaced solution procedures. Specifically, the attitude encoding the body frame changes and gyroscopes drift biases are estimated through attitude estimation while ...

Optimal Attitude Estimation and Filtering Without Using Local Coordinates Part I: Uncontrolled and Deterministic Attitude Dynamics [PDF]

arXiv, 2005
There are several attitude estimation algorithms in existence, all of which use local coordinate representations for the group of rigid body orientations. All local coordinate representations of the group of orientations have associated problems.

Attitude and Gyro Bias Estimation Using GPS and IMU Measurements

, 2017
We propose an attitude and gyro-bias estimation scheme for accelerated rigid body systems using an inertial measurement unit (IMU) and a global positioning system (GPS).
