The aim of this study is to investigate the long term evolution of the orbital inclination of SIRIO satellite. In fact, since 1983, SIRIO orbit inclination can no longer be controlled because of the scarce quantity of fuel remaining on board.While its attitude and longitude are still controlled, the orbit inclination Is changing according to the environmental perturbing forces acting on the satellite. To evaluate this long term effect a simp1ified model is given. A comparison has been made with results obtained uSing mOre precise, but time consuming computer programs. The method presented is applicable to any near-geostationary orbit.

Abstract
The aim of this study is to investigate the long term evolution of the orbital inclination of SIRIO satellite. In fact, since 1983, SIRIO orbit inclination can no longer be controlled because of the scarce quantity of fuel remaining on board.While its attitude and longitude are still controlled, the orbit inclination Is changing according to the environmental perturbing forces acting on the satellite. To evaluate this long term effect a simp1ified model is given. A comparison has been made with results obtained uSing mOre precise, but time consuming computer programs. The method presented is applicable to any near-geostationary orbit.| File | Dimensione | Formato | |
