“…For satellites in GEO, the fundamental perturbations are solar and lunar gravitational attractions that induce drift in orbital inclination and solar radiation pressure that affects orbit eccentricity [2]. Station-keeping (SK) maneuvers include a series of planned and unplanned correction maneuvers implemented by RCT to counteract these perturbations while maintaining satellite attitude [3]. Planned SK maneuvers were executed to keep the satellite in a predefined window at a required fixed orbital slot and have the antennas point to a defined footprint.…”

This paper introduces a theoretical description, force, and torque analysis of a Reaction Control Thruster (RCT) used as an actuator in Attitude Determination and Control Subsystem (ADCS). Mathematical formalization, realization, and implementation are offered to implement the RCT model using Matlab-Simulink. Furthermore, this paper proposes an accurate RCT Simulink model to control the orientation and stabilizes the Geostationary Earth Orbit (GEO) satellite within its orbit. Finally, a comparative analysis is carried out with an existing satellite platform (Eurostar-3000) based on the Root Mean Square Error (RMSE) for the delta velocity (delta-𝒱) parameter. The outcomes of the model simulation validated the effectiveness of the proposed approach.

“…28, it is still very competitive because they considered the on-off nature of the thruster. Unlike these three studies, Zou et al considered the geostationary station-keeping problem with the MPC as an optimization problem based on the orbital elements instead of the position and velocity [33]. In their study, they combined the linearized relative element model proposed in Ref.…”

We propose two approaches based on feedforward control and model-predictive control, respectively, to solve the station-keeping problem of an electric-propulsion geostationary Earth orbit (GEO) satellite, whose thrusters are mounted on two robotic arms on its anti-nadir face. This novel configuration enables a wider range of thrust direction, making it possible to regard the thrust direction as control variables. To solve this control problem, we present the quick feedforward controller (QFFC) and the fuel-optimal model predictive controller (FOMPC). The QFFC is developed based on the analysis of GEO dynamics and the thruster configuration. The FOMPC applies an optimization algorithm to solve the nonlinear model predictive control (NLMPC) problem with the initial value given by the QFFC. Numerical simulations suggest that both controllers could achieve stable station-keeping over multiple objective elements with fewer thrusters and fewer maneuvers. The QFFC has higher control accuracy and lower computational requirements than the FOMPC, whereas the FOMPC could significantly save fuel consumption. The robustness assessment and other discussions of the controllers are also presented.
