ABSTRACT:
Apparatus and method of determining a roll reference for strap down seeker in a spinning projectile is shown to consist of the steps of: (a) determining the frequency spectrum of signals out of an accelerometer disposed in such missile to be sensitive to roll, precession and nutation forces; (b) separating the signals caused to the roll forces; and (c) processing the separated signals to determine the roll reference.
