Abstract: For model predictive control for a spacecraft formation, a method calculates a virtual point that represents a plurality of spacecraft orbiting in a spacecraft formation. The method calculates an outer polytope boundary and an inner polytope boundary relative to the virtual point for a given spacecraft of the plurality of spacecraft. The method maneuvers the given spacecraft to within the inner polytope boundary using model predictive control (MPC) to minimize fuel consumption.

Abstract: For generating a points-of-interest plan, a method generates communication graph nodes for at least one satellite. The method calculates communication graph edges from the communication graph nodes, wherein the communication graph nodes and the communication graph edges comprise a communication graph. The method solves the communication graph to yield a communication plan. The method generates a points-of-interest plan from the communication plan.
