A Low Cost, Single GPS Frequency (L1), MEMS Based, Attitude and Positioning Determination System For Weapon Testing

H. Baker and S. Goodrich

Abstract:	The 46th Test Wing at Eglin Air Force Base, in conjunction with Waypoint Consulting, has developed a low cost, L1 only, MEMS based IMU, attitude determination system. The system accuracies are plus and minus ½ degree in heading and pitch and .2 meters in position. Roll is also available. The system fits inside a standard weapon 3' bomb fuze well. Commercial off the shelf GPS receivers and MEMS IMU were used for the system. A microcontroller was used to time tag the IMU data with GPS time. Information is transmitted to the ground for near real-time solution computation. Waypoint's Inertial Explorer software was used to compute a loosely coupled solution. A system description, Truck Tests and Weapon Test Results follow. Total system hardware is targeted at less than $30K. The system can ultimately be used for over the water attitude determination on weapon flight and impact.
