Acoustic noise reduction in the MK 49 ship's inertial navigation system (SINS)
Sperry Marine has devised a passive structure-borne noise isolation system that reduces the noise generated by dithered ring laser gyroscopes to levels below the requirements of MIL-STD-740-2. Descriptions of some of the analytical and experimental processes required to develop this system are presented, together with structure-borne noise test results. Results show that a 47-dB structure-borne noise reduction has been achieved with a noise isolation system that is compatible with the stability and repeatability required by navigation systems. The noise reduction techniques presented have enabled Sperry Marine to develop a dithered ring laser gyroscope navigator feasible for naval applications, the MK 49.<>
