It is necessary to measure the real-time rotation speed and the roll angle of a projectile relative to the geodetic coordinate system in order to achieve accurate guidance.To obtain the rotation speed of the projectile,a single antenna satellite receiver is used to receive the satellite signal.Since the received signal can provide amplitude modulation information relative to the roll characteristic of projectile,the signal can be demodulated to determine the rotation speed of the projectile.
