Abstract
In this paper the control of tetrahedron satellite formation flying in the geosynchronous orbit GEO using solar radiation pressure is investigated The long term disturbing effect of the main zonal and tesseral harmonics J 2 and J 22 of the geopotential are eliminated by adjusting the initial orbital elements and a tetrahedron satellite formation flying in the GEO is designed Then a control system using solar radiation pressure is further proposed to maintain the tetrahedron satellite formation in which a sliding mode control SMC is developed to determine the control force The control force is acquired from the solar sails equipped on the satellites and the final control law and strategy using solar radiation pressure are presented Moreover three kinds of numerical simulations are especially given to verify the validity of the control system using solar radiation It shows that Laplace precession of the GEO satellite can be avoided effectively and the inplane and outofplane errors of the formation can be eliminated easily And hence the control of tetrahedron satellite formation flying in the GEO using solar radiation pressure is proved to be feasible
