From the satellite being assumed to be in its orbit, the assumed measurement data of the three-axis magnetometer is obtained. They contain the reference measurement of the Earth’s magnetic field which can be translated reference attitude information of the satellite and that of measurement uncertainties of the magnetometer. The reference measurement data is made from the assumed attitude angles during its operation. Obtained measurement data are analyzed using TRIAD and QUEST (QUaternion ESTimator) algorithm, and then the satellite attitude information in the forma of Euler angles is estimated. In order to produce the measurement data, the Earth’s magnetic field is simulated earlier. Simulations and the performance examination based upon the proposedalgorithm are conducted.
