Path: FormationFlying/Transformation
% Computes the desired orbital element differences, given the formation flying
"goals" and the measured orbital elements.
Since version 7.
--------------------------------------------------------------------------
Form:
dEl = Goals2DeltaElem( el0, goals, J2 );
--------------------------------------------------------------------------
------
Inputs
------
el0 (1,6) Measured orbital elements (Alfriend format) [a,theta,i,q1,q2,W]
goals (.) Geometric goals data structure with following fields:
- y0 (1,:) along-track offset [km]
- aE (1,:) semi-major axis of relative ellipse [km]
- beta0 (1,:) angle on ellipse at perigee [rad]
- zInc (1,:) cross-track amplitude due to inclination diff [km]
- zLan (1,:) cross-track amplitude due to right ascen diff [km]
J2 (1) Size of the J2 perturbation (default 0)

Outputs
-------
dEl (:,6) desired orbital element differences
