…nozzles are used to stabilize the inertial platform as commanded from the sensors to increase accuracy. This design not only eliminates the problem of gimbal lock, but also makes it extremely accurate (drift less than 1.5×10−5 °/h), to the point that any further improvement would give a negligible benefit to the…
