Abstract:Minimum-fuel trajectories in the Clohessy-Wiltshire orbital model are investigated. Low-thrust variable-specific-impulse propulsion is assumed. The necessary conditions for an optimal solution and the equations of motion are combined to produce a single equation. Every solution to this equation is an optimal trajectory. Boundary conditions for rendezvous and intercept trajectories are formulated and optimal solutions are obtained. Previous analytical solutions are examined and reconciled.
