- W2312872393 abstract "The first of two Sentinel-2 Earth observation satellites is currently under development by EADS Astrium Satellites for the Europen Space Agency. Its Attitude and Orbit Control System design is strongly influenced by the safe mode autonomy requirement of two times 20 days within 7.25 years satellite lifetime. In this paper two controller approaches for Earth-oriented safe mode using low-accuracy attitude and angular rate sensors are analyzed. While the first approach is derived from SISO control theory, the second is based on periodical MIMO systems. It is shown how the desired control torque can be optimally distributed between magnetic torquers and thrusters. The stability of the control loops is analyzed analytically by Floquet theory and numerically by Monte Carlo simulation. In addition, a method for estimating the yaw angle from angular rate measurements is introduced and applied to both controller types. The evaluation of the controller approaches is done regarding achievable attitude performance, number of thruster pulses and fuel consumption. As a result the second controller approach accomplishes a reduction of 29% and 53% for number of thruster pulses and accumulated thruster on-times, respectively. In addition, the thruster activity reduces by further 83% and 52%, respectively, considering not only attitude but also angular rate measurements to flag the thruster activation." @default.
