Path: Orbit/RHSOrbit
% High fidelity orbit model right-hand-side.
Includes higher harmonics of the earth's gravitational field and sun and
moon accelerations as options.
- The drag option = drag coefficient * area / mass where the area is in m^2
- The sun option = area / mass
- The moon option is 0 or 1
The gravity model should be unnormalized.
--------------------------------------------------------------------------
Form:
xDot = FOrbHF( x, t, options, jD, aExt, mu, s, c, j, a )
xDot = FOrbHF( x, t, options, jD, aExt, d )
xDot = FOrbHF( t, x, options, jD, aExt, mu, s, c, j, a ) (for ode113)
