| Description |
The Sequential Gradient Restoration Algorithm (SGRA) is an indirect optimisation method based on the iterativealternation of two phases: in the rst one (gradient), the objective is the minimisation of the cost function; in the secondphase (restoration) the objective is the fullment of the dierential equations, equality and inequality path constraintsand boundary conditions. This paper illustrates the application of the SGRA to the generation of very long transfertrajectories (up to some few thousand orbits during several months) in a typical GTO to GEO transfer scenario performedwith electric propulsion. The reason for using electric propulsion in that case is the signicant propellant mass savings ifcompared to the classical chemical propulsion strategies, at the expenses of an elongated transfer phase (from few daysto some months). The electric propulsion system considered in this paper is characterised by thrust levels between 100mN and 1 N (for some 3 to 5 tons launch mass) and high specic impulse, between 1000 s and 5000 s
