Path: SCPro/DynamicalModels
% Right-hand-side of spacecraft dynamical equations with a second spacecraft. This is a rigid body with an external force and torque input. The position is in km. The gravity model is for a point mass. The prime spacecraft has attitude dynamics, the target has only point mass dynamics (position and velocity.) The force and torque are constant across the integration time step.
