A reconfigurable unscented Kalman filter (UKF)-based estimation algorithm for magnetometer biases and scale factors is proposed as a part of the attitude estimation scheme of a pico satellite. Unlike existing algorithms, in this paper, scale factors are not treated, together with other parameters, as part of the state vector; they are estimated separately. After satisfying the conditions of the proposed stopping rule for bias estimation, UKF reconfigures itself for estimation of attitude parameters alone.

Reconfigurable UKF for in-flight magnetometer calibration and attitude parameter estimation Söken, Halil Ersin (2011-01-01) In this study a reconfigurable unscented Kalman filter (UKF) based algorithm for the estimation of magnetometer biases and scale factors is proposed as a part of the attitude estimation scheme of a pico satellite. Algorithm is composed of two stages; in first stage UKF estimates magnetometer biases and scale factors as well as six attitude parameters of the satellite. Differently from the existing algorithms, scale factors are not treated together with the other parameters as a part of the state vector; thr...
UKF for the Identification of the Pico Satellite Attitude Dynamics Parameters and the External Torques on IMU and Magnetometer Measurements Söken, Halil Ersin (2009-01-01) In this study, an Unscented Kalman Filter (UKF) algorithm, which integrates mathematical model of the attitude dynamics with the measurements of Inertial Measurement Unit (IMU) and the magnetometers, is designed. The identified vector is arranged from the Eider angles, angular rates, and the unknown constant components of the external torques (the gravity-gradient, magnetic field pressure and the sun radiation) acting on the pico satellite. Because of the inherent nonlinear dynamics and the nonlinear measur...
UKF based in-flight calibration of magnetometers and rate gyros for pico satellite attitude determination Söken, Halil Ersin (Wiley, 2012-05-01) In this paper an unscented Kalman filter based procedure for the bias estimation of both the magnetometers and the gyros carried onboard a pico satellite, is proposed. At the initial phase, biases of three orthogonally located magnetometers are estimated as well as the attitude and attitude rates of the satellite. During the initial period after the orbit injection, gyro measurements are accepted as bias free since the precise gyros are working accurately and the accumulated gyro biases are negligible. At t...
UKF based on-orbit gyro and magnetometer bias estimation as a part of the attitude determination procedure for a small satellite Söken, Halil Ersin (2011-12-01) In this study an unscented Kalman filter (UKF) based magnetometer and gyro bias estimation algorithm is presented as a part of the attitude determination procedure for a small satellite, which has three magnetometers and three gyros as measurement sensors. Differently from the existing studies both magnetometer and gyro biases are estimated as well as the attitude parameters. Kinematics of the satellite is modeled via using quaternion parameterization. In order to enable estimation of all parameters simulta...
UKF based in-flight calibration of magnetometers and rate gyros for pico satellite attitude determination Söken, Halil Ersin (2010-01-01) In this paper an Unscented Kalman filter based procedure for the bias estimation of both the magnetometers and the gyros, which are carried onboard by a pico satellite, is proposed. At the initial phase, biases of three orthogonally located magnetometers are estimated as well as the attitude and attitude rates of the satellite.
