Robust Kalman filtering for small satellite attitude estimation in the presence of measurement faults
In normal working conditions it is possible to achieve sufficient attitude estimation accuracy for a satellite using regular Kalman filter algorithm. On the other hand, when there is a fault in the measurements, the Kalman filter fails in providing the required accuracy and may even collapse over time. In this paper, a Robust Kalman filtering method is proposed for the attitude estimation probl...
متن کاملA robust strong tracking cubature Kalman filter for spacecraft attitude estimation with quaternion constraint
This paper considers a robust strong tracking nonlinear filtering problem in the case there are model uncertainties including the model mismatch, unknown disturbance and status mutation in the spacecraft attitude estimation system with quaternion constraint. Two multiple fading factor matrices are employed to regulate the prediction error covariance matrix, which guarantees its symmetry. The sp...
متن کاملOn Continuous-Discrete Cubature Kalman Filtering
This paper is concerned with application of cubature integration methods to Kalman filtering of discretely observed non-linear stochastic continuous-time systems. We compare two recently proposed variants of the continuous-discrete cubature Kalman filter (CD-CKF), which differ in the order how the discretization and the Gaussian approximation are done. Aside with theoretical analysis we test th...
متن کاملInexpensive Cubesat Attitude Estimation Using Quaternions and Unscented Kalman Filtering
This paper describes a quaternion implementation of an Unscented Kalman Filter for attitude estimation on CubeSats using measurements of a sun vector, a magnetic field vector and angular velocity. For faster convergence of the attitude estimate, a SVD-method solving Wahba’s problem has been proposed, which provides an initial attitude estimate. Using unit quaternions provides a singularity free...
متن کاملHybrid Cubature Kalman filtering for identifying nonlinear models from sampled recording: Estimation of neuronal dynamics
Kalman filtering methods have long been regarded as efficient adaptive Bayesian techniques for estimating hidden states in models of linear dynamical systems under Gaussian uncertainty. Recent advents of the Cubature Kalman filter (CKF) have extended this efficient estimation property to nonlinear systems, and also to hybrid nonlinear problems where by the processes are continuous and the obser...
