In case of normal operational conditions for a satellite, a conventional Kalman Filter gives sufficiently good attitude estimation results. On the other hand, when there is a fault in the measurements then the Kalman filter fails about providing the required accuracy and may even collapse by time. In this paper, a Robust Kalman filtering method is proposed for the attitude estimation problem. By using the proposed method both the Extended Kalman Filter and Unscented Kalman Filter are modified and the new algorithms, which are robust against the measurement malfunctions, are called as the Robust Extended Kalman Filter (REKF) and Robust Unscented Kalman Filter (RUKF), respectively. The adaptation is performed following both single and multiple scale factor based schemes. As an application example the proposed algorithms are applied for attitude estimation of a small satellite and the performance of the robust Kalman filters are compared in case of different measurement faults.

Robust Attitude Estimation Using IMU-Only Measurements Candan, Batu; Söken, Halil Ersin (2021-01-01) © 1963-2012 IEEE.This article proposes two novel covariance-tuning methods to form a robust Kalman filter (RKF) algorithm for attitude (i.e., roll and pitch) estimation using the measurements of only an inertial measurement unit (IMU). KF-based and complementary filtering (CF)-based approaches are the two common methods for solving the attitude estimation problem. Efficiency and optimality of the KF-based attitude filters are correlated with appropriate tuning of the covariance matrices. Manual tuning proce...
Exact kalman filtering of respiratory motion Çetinkaya, Mehmet; Erkmen, Aydan Müşerref (2018-10-01) In this paper we propose a novel Exact Kalman Filter for state estimation of quasi-periodic signals such as respiratory motion. Nonlinear functions of interest are approximations as truncated Fourier series. Instead of relying on approximations provided by Extended Kalman Filter or Unscented Kalman Filter, our filter performs exact calculation of the mean and covariances of interest. We then compare, through simulations, the performance of our filter to the two. Our results show that the theoretically deriv...
Robust Kalman filtering for small satellite attitude estimation in the presence of measurement faults Söken, Halil Ersin; Sakai, Shin-ichiro (Elsevier BV, 2014-03-01) 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 problem. By using the proposed method both the Extended Kalman Filter and Unscented Kalman Filter are modified and the n...
Design of attitude estimation algorithms for inertial sensors only measurement scenarios Candan, Batu; Söken, Halil Ersin; Department of Aerospace Engineering (2022-3-24) This thesis proposes four novel robust Kalman filter algorithms for attitude estimation using only the measurements of an inertial measurement unit. Efficiency and optimality of the Kalman filter based attitude filters are correlated with appropriate tuning of the covariance matrices. Manual tuning process is a difficult and time-consuming task. Specifically, the inertial measurement unit-only attitude estimation filters are prone to the external accelerations unless their covariances are adapted to gain ro...
REKF and RUKF development for pico satellite attitude estimation in the presence of measurement faults Söken, Halil Ersin (2011-09-01) When a pico satellite is under normal operational conditions, whether it is Extended or Unscented, a conventional Kalman Filter gives sufficiently good estimation results. However, if the measurements are not reliable because of any kind of malfunction in the estimation system, Kalman filter gives inaccurate results and diverges by time. This study compares two different robust Kalman filtering algorithms; Robust Extended Kalman Filter (REKF) and Robust Unscented Kalman Filter (REKF) for the case of measure...
