A true geostationary orbit is almost never achieved. Geostationary means inclination = 0 and e =0. In most cases, you donât want this. Certainly not e = 0, though you do want e to be small, but still measurable/computable. The reason why is that if your eccentricity = 0, then your argument of perigee is undefined, which makes it hard to compute a Keplerian vector.
