Based upon a discussion on the merits and limitations of proportional navigation (PN) guidance law in which constant gravity compensation is included as a part, a counterpart having varying compensations, which changes with pitching angle and line-of-sight angle, is substituted. Flight trajectory simulation over a submissile model is conducted, resulting in increased impact angle, shorter miss distance, smaller maximum normal overload and narrower terminal angle of attack.
