“…The extended Kalman filter is the nonlinear version of the Kalman filter which makes use of the nominal nonlinear system dynamics to predict the evolution of the state while it uses updated local linearisations of the nonlinear system at the currect estimated state to estimate the covariance of the state vector [24]. Many authors have also used the EKF approach to reconstruct the spacecraft attitude parameters [25], [26]. Here, the state estimatesẑ k are updated according to the nonlinear equation…”

“…As result, the LEO satellite dynamic model is expressed as 3 ( ) r μ γ = + r = -r + f r w (7) where w = [w x w y w z ] T is the process noise.…”

“…Since the appearance of the (LEO) satellite, the EMF has been applied to determine satellite orbit and attitude in LEO satellites. The use of the magnetometers measurements for hybrid navigation has attracted much attention in research community and has been the subject of many publications [1][2][3][4][5][6][7][8].…”

“…Previous study of the three-axis attitude determination for LEO satellite using only magnetometer measurement is successfully presented in [14], [15] which estimated small attitude and rate angle and produce acceptable attitude and rate error. A similar approach was performed for LEO EgyptSat-2 using only magnetometer measurement at big attitude angle (in detumbling mode) was presented in [16] and showed that estimated attitude produced quite big attitude error.…”

“…Time update is used to predict next estimate value and measurement update is used to correct the error. Attitude estimation using EKF is initiated by describing non-linear differential equation of a dynamic system [6], [15], [27]. The general nonlinear differential equation is defined as,…”
