In 2022 an unprecedented long-term test was conducted with the NSM over a total period of 7 months (March to September). For this purpose, the NSM was installed on a frigate that was on a mission in the Mediterranean Sea. The Gyro Mount was placed in an elevated position on a mast high above the ship’s pivot, which represents a typical but also challenging case of application for the gyro gimbal, since this pivot offset causes the angular movements to result in tangential accelerations, to which additional sway, heave and surge accelerations add up. The task of the gimbal was to stabilize a panoramic, long-range, wide area surveillance sensor system.

Sebastian Schreiber, CTO at SOMAG comments: “The NSM is a real workhorse. The data we got from the test shows that the gyro gimbal delivers the best stabilization performance even over a long period of time and under different weather and water conditions, providing exceptionally sharp data and comprehensive situational awareness.”

The white line in the data sample shows the excitation of the ship, which moved in the roll axis up to almost +15°. The sensor on the other hand (yellow line) remained stable during this time and showed a residual deviation from perpendicular of just 0.11°. The use of the Nautical Gyro Stabilization Mount reduced the existing movements of the sensor system by about 45 times in this mission data example.

In addition to this long-term test, further quality tests have been performed and successfully passed with the NSM in recent months, including a temperature test, an IP class test and a vibration test. The evolved NSM 500 features advanced control algorithms, enhanced diagnosis possibilities and an Ethernet communication interface that allows integration into existing networks as well as control and monitoring of multiple Gyro Mounts within the network.

The new NSM 500 is commercially available as of now. For further questions and prices please contact SOMAG sales team.
