A projectile guidance system without gyros in which the projectile has an orthogonal body coordinate system. The projectile has a triax of accelerometers providing x, y and z acceleration data measured along the x, y and z axes respectively. A GPS antenna and receiver means provides onboard GPS position and velocity data in earth referenced navigational coordinates. A computer and program means stores and accesses time indexed GPS position and GPS velocity data and transforms x, y and z axis acceleration data from body to navigation coordinates. The prog...
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 ...
