Abstract:
1. A projectile guidance system with accelerometers and a GPS receiver comprising: a projectile having a triax of accelerometers mounted in the projectile and providing roll, pitch and azimuth axis acceleration data; a GPS antenna and receiver means mounted in the projectile for providing and updating present position data; a computer and memory mounted in the projectile and executing a guidance program; and divert propulsion means; wherein the guidance program is responsive to the roll, pitch and azimuth axis acceleration data and to the sampled present position data for calculating and outputting time indexed roll, pitch and azimuth angles, time indexed present position and velocity to a flight control system for guiding the projectile to a predetermined target location; and wherein the divert propulsion means are responsive to the guidance program.
