| Abstract: | An east-west station-keeping control strategy suitable for a V-wheel control systems is proposed for a GEO satellite in orbit. First, the V-wheel control system is analyzed and a calculation method to calibrate the thruster efficiency is derived. Then a model of the effect of momentum dumping on orbit is developed. The influence of attitude control on station-keeping rings and eccentricities is also studied in detail. Finally a control strategy is developed to extend the period of station-keeping control. The method is shown to be a success in practice. |
| Keywords: | V-wheel control system thruster efficiency calibration east-west station-keeping attitude control orbit control control strategy optimization |
