DERIVATION OF THE GUIDANCE EQUATIONS FOR THE USAF ATHENA
Abstract
The USAF ATHENA is a re-entry test vehicle which has four solid propellant stages. A midcourse correction type of guidance is used to compensate for boost dispersions by adjusting the third stage attitude and ignition time. The guidance computations are performed in a ground based digital computer using radar data obtained after second stage burnout. Because this is a re-entry test vehicle, the guidance system must cause the payload to meet various re-entry constraints as well as the usual impact point constraint. The complete derivation of the guidance equations and a description of the entire guidance loop are presented in this report.
