% Closed form solution of relative orbital motion using Hills equations. Relative state expressed in Spacecraft-Local-Orbit (SLO) coordinate frame. Since version 10. ------------------------------------------------------------------------------- Form: X = HillsEqnsSLO( Xo, w, t ) ------------------------------------------------------------------------------- ------ Inputs ------ Xo (6,nSC) Initial state in SLO frame, length unit [L], velocity unit [L/sec] * each column is the state of a s/c, [x; y; z; xdot; ydot; zdot] w (1) Orbital Rate (rad/s) t (:) time vector (sec) flag (1,1) If entered, the output is formatted as a (6,nSC) matrix. ------- Outputs ------- X (6*nSC,:) Position and velocity over time -------------------------------------------------------------------------------
