EQUILIBRIUM POSITIONS OF A CABLE-CONNECTED SATELLITES SYSTEM UNDER THE INFLUENCE OF SOLAR RADIATION PRESSURE, EARTH'S SHADOW, EARTH'S OBLATENESS AND AIR RESISTANCE: ELLIPTICAL ORBIT
... We study the equilibrium positions of the motion of a system of two cable-connected artificial satellites under the influence of solar radiation pressure, earth's oblateness, shadow of the earth and air resistance. The ...

Effects of a Time Varying Moment on a Large Tethered Satellite in Circular or Elliptical Orbit
... The purpose of this paper is to investigate the effect of a varying moment on the rotation angle of a large tethered satellite that is orbiting a planet. Two different types of orbits were investigated: a simple circular ...
