% Simple demo to compute drag over one orbit Assumes point mass s/c, two body propagation. The only perturbing acceleration considered is due to drag. Mass is assumed to be constant, fixed cross-sectional area and drag coefficient. Demo produces plots of spacecraft position and velocity (in ECI frame) and drag force (N) (in ECI frame). DV due to drag perturbation is displayed.
