Path: Orbit/OrbitManeuver
% Computes the delta-V for a phase change. The velocity change is tangent to the orbit. The separation angle is positive when the interceptor leads the target. In this case the transfer orbit is larger than the target orbit. When the separation angle is negative and the interceptor trails the target, the transfer orbit is smaller. Has a built-in demo for low Earth orbit. -------------------------------------------------------------------------- Form: deltaV = OrbMnvrPhaseChange( a0, deltaA, kTarget, mu ) -------------------------------------------------------------------------- ------ Inputs ------ a0 (1,1) Initial semi-major axis deltaA (1,1) Initial separation (rad) kTarget (1,1) Number of revolutions (1,...) mu (1,1) Gravitational parameter (km^3/sec^2) ------- Outputs ------- deltaV (1,1) Required delta-V -------------------------------------------------------------------------- Vallado, D.
