A configuration based upon a 24-cm path length TRILAG gyro, three miniature single-axis force rebalance accelerometers, and a digital signal processor is presented. The resulting inertial sensor element provides navigation performance equal to a conventional medium-accuracy navigation system (0.4 to 1 nmi/h) with half the weight and volume of a traditional Ring Laser Gyro (RLG) configuration. Its application as a stand-alone inertial subsystem or as an integral part of a full inertial navigation system is discussed and performance data presented. Companion development utilizing down-sized TRILAG gyros for tactical missile or sensor stabilization applications is also reviewed.
