Modern army tactical vehicles field artillery forward observes and weapons launching platforms require highly accurate azimuth reference devices that are simple, small, rugged and low in cost. Gyrocompass technology has evolved very slowly and current state of the art device are characterized by high cost and high sensitivity to vibration, shock and motion induced errors. The proposed gyroart I gyrocompass represents a significant advance and promises to provide the army with a low cost azimuth measuring device that is largely insensitive to battlefield disturbance and provide an azimuth accuracy of 1.69 arcminutes when operated on army tactical vehicles and large caliber weapons while firing. Since gyroart has already made substantial investments in design and study of gyroart I for battlefield fo applications, the phase I objective will be to demonstrate that the gyroart I approach will meet the army's requirements for vehicles and large caliber weapons.
