Abstract: The effect of perigee height on aeroassisted orbital plane change is studied.Using sequential quadratic programming,trajectories which minimize the impulse required to change the orbital plane and maximize the inclination change are calculated for different perigee heights.In each case,the stagnation heating rate is limited.Results show that with the increment of the perigee height,the ability to change orbital plane and robustness to the initial conditions are both decreased.In general,the perigee height should not be too large in aeroassisted orbital plane change.
