Abstract : A method of estimating ballistic missile attitude during the powered-flight period from track and rate observations recorded at the Mk II Complex at PMR is contained herein. The method, which consists of differentiating smoothed velocity data to obtain the total missile acceleration vector in inertial space, permits one to solve for the thrust acceleration vector, which on the average for all but near-instantaneous angular velocities is considered coincident with the roll axis of a roll-stabilized missile. From missile attitudes and accelerations, antenna look angles may be obtained for analysis of ground-toairborne tracking during powered flight. (Author)
