% Get Hills transformation matrices This function takes the position and velocity of a satellite in the ECI frame, and returns the A and Adot matrices used for transformation to the Hills frame. They are used in the following equations: rH = A*(r1-r0); vH = A*(v1-v0) + Adot*(r1-r0); -------------------------------------------------------------------------- Form: [A, Adot] = GetHillsMats( r0, v0 ) -------------------------------------------------------------------------- ------ Inputs ------ r0 (3,1) Position ECI frame v0 (3,1) Velocity ECI frame ------- Outputs ------- A (3,3) Rotation matrix (position) Adot (3,3) Rotation matrix (velocity) Equal to -Cross( OrbRate(Mag(r0), A ) --------------------------------------------------------------------------
