Nato Exercise

NSM 400 as part of counter-drone system

SOMAG’s NSM 400, a Gyro Stabilization Mount designed to enhance the performance of sensors systems in mobile applications, is part of the counter-drone system Snow Leopard. The system is an evolution of Elettronica’s ADRIAN anti-drone system and was presented in early March on the occasion of NATO’s innovative White Fox exercise and conference held in Sestriere, Italy.

The system is characterized by its capabilities to operate in motion and under extreme operating conditions by using artificial intelligence techniques combined with signal analysis and image processing. Based on the operational requirements and concept of operations, the anti-drone system uses electro-optical devices and RS Scanner/DF as the only detection sensors. The stabilization platform compensates for vehicle movements in the roll and pitch axes in real time and precisely levels the sensor system to enable the identification and classification of drones at a distance. This guarantees an adequate response time.

The NSM 400 can be deployed on any kind of mobile vehicle. For this particular demonstration, the whole system was installed on a BV S7 vehicle of the Italian Army, but can also be installed on any other vehicle to provide protection for dismounted convoys and fixed targets.

NSM 400

Successfully Completes Stabilization Performance Test

SOMAG AG AG Jena has successfully tested the stabilization performance of its Nautical Stabilization Mount 400 at the Institute of Ship Technology and Transport Systems of the University of Duisburg-Essen.

The NSM 400 was designed to stabilize sensor systems on medium to large maritime vessels even in very rough sea conditions, ensuring a stabilized field of view and high-resolution images by compensating the swell up to sea state 6 and beyond.

Extensive research on ship motion in different sea states show rotary motion given by roll, pitch and yaw and a strong presence of linear accelerations along all 3 axes.

Placing the Stabilization Mount in an elevated position on a mast high above the ship’s pivot represents a typical but also challenging case of application. This pivot offset causes the angular movements to result in tangential accelerations, to which additional sway, heave and surge accelerations add up.

„We used comprehensive data from US Navy ship motion studies and picked out the worst-ever recorded cases to calculate the maximum angles, max. angular velocities, max. angular accelerations and max. tangential accelerations occurring for our application at sea state 6,” says Jens Korneli, Application Engineer at SOMAG AG Jena.

Previous performance tests using the SOMAG test bed could already successfully demonstrate the NSM 400 stabilization performance. However, these tests were limited to roll and pitch motion only. To reproduce tangential acceleration, a hexapod test bed was chosen to simulate real-life ship motions.

A total of 13 different hexapod tests were performed simulating movements up to 20° in roll and pitch and lateral accelerations up to 0.5 g.

The residual angular deviation from perpendicular was measured with a reference sensor system to verify the stabilization performance of the Mount. The NSM 400 has successfully completed all 13 tests, delivering on the promise of an unmatched stabilization accuracy of ≤0.4° rms without external IMU data.

“The NSM 400 performance went above and beyond our own specifications and proved an average residual angular deviation of 0.17° rms,” Sebastian Schreiber, CTO at SOMAG AG Jena, summarizes the results.

“However, we do not simply stop at this point” he continues. “In order to resemble the real-life challenges of seafaring more closely, we used motion data actually recorded from an LNG tanker fighting its way through waves of 9 m (30 ft.) and higher, which corresponds to sea state 7.”

Heavy swell like this pushes man and machine to their limits, but the NSM400 is not impressed at all, perfectly stabilizing the 41 kg (90,38 lbs.) payload. The measured residual angular deviation of no more than 0.12° rms once again proves that the gimbal is more than capable of getting its job done, just relying on its build in sensors.

Performance Test Video

The results of the hexapod-test using real-life ship data is shown in the video. The IMU on top of the Mount measures the residual angular deviation in roll (blue line) and pitch (green line) to prove the stabilization performance. The rms values in the diagram change according to the residual angular deviation in the respective moment.

SOMAG AG Jena launches

Nautical Gyro Stabilization Mount NSM 400

With the launch of the NSM 400 SOMAG AG Jena has expanded its maritime portfolio’s capabilities. The NSM 400 is a medium-sized device between the smaller RSM 400 and the larger OSM 4000 and complements the product portfolio of Gyro Stabilization Platforms, which are designed for land and offshore use.

Reliable Gyro Stabilization for Surveillance Sensors

The NSM 400 was primarily designed for the stabilization of surveillance sensors on medium (starting from 1.0 kt onwards) to large maritime vessels. Un-stabilized systems follow the movement of the water caused by the swell which adversely affects the detection and threat-tracking capabilities of the sensor. Using a Gyro Stabilization Mount ensures a stabilized field of view and high-resolution images by compensating the movements of the vessel. This allows EO/IR systems to scan their environment without interference even in extreme sea conditions, in order to best detect, track and classify asymmetric air and surface threats. The NSM 400 is the perfect gimbal for IRST (infra-red search and track) and other surveillance systems to ensure 360° protection for surface vessels of naval forces.

Highest torque and stabilization range for the best gimbal performance on the market

Like all SOMAG marine Mounts, the NSM 400 is IP 67 compliant and made to perform in very rough sea conditions, up to sea state 6 and beyond. To achieve this performance, the NSM 400 features a peak torque of 350 Nm to withstand even 1.5 G lateral acceleration*. Users who choose an NSM 400 not only opt for an extremely powerful Mount, but also for one with a uniquely large stabilization range. The NSM 400 compensates for movements in roll and pitch up to ≤±20°. Even an installation at high altitudes, such as on 30-meter high masts, does not affect its performance. Designed to work 24/7 it offers an unmatched stabilization accuracy of ≤0.4° rms without external IMU data. It is also possible to feed in NMEA frames or ship data to improve the long-term stabilization performance of the Mount.

NSM 400 offers new communication standards

The NSM 400 offers another innovation as it is the first stabilization platform equipped with an Ethernet port. This enables the user to integrate the Mount into a network. Numerous advantages result from this, such as communication with the Mount over long distances and the possibility to easily access the Mount from different devices within the network as well as the simultaneous configuration if several Mounts are integrated in the network.

For further questions and prices please contact the SOMAG sales team at info@somag-ag.de

*The possible payload to be stabilized is related to the center of gravity of the payload as well as the lateral accelerations the Gyro Mount and payload have to withstand. Please do not hesitate to contact us if you have any questions in this regard. In order to give you the best possible assistance, please include the following information in your request:

Where should the Mount be installed (floating platform, buoy, ship etc.)?
Dimensions (length/width/weight) of the platform or vessel
How many meters above the waterline should the Mount and the payload be installed?
Center of gravity and weight of the payload
Further information you consider important

SOMAG AG Jena to deliver Gyro Mount to Green Rebel Group

Aerial ecology survey with GSM 4000

Green Rebel Group recently purchased a Gyro Stabilization Mount GSM 4000, the flagship of the SOMAG airborne Gyro Mount line. The Mount was installed in the nose pod of a Diamond DA42 MPP aircraft, which was officially delivered in May 2021. Green Rebel, specializing in data acquisition and analytics to support offshore renewable energy development, acquired the aircraft to conduct aerial ecology surveys off the coast of Ireland. These data will be used to support consent applications for offshore renewable energy developments. As part of this work, large sections of the ocean will be surveyed on a regular basis.

Sarah Kandrot, Head of Aerial Surveys with Green Rebel Group said: “The data are used to map the abundance of marine life to ensure that offshore wind farms are built in the most suitable locations to protect the ecology of the ocean.”

To capture the high-resolution RGB aerial images, the Irish company uses two aerial cameras which are stabilized by the GSM 4000. The Gyro Mount dynamically compensates for arbitrary aircraft movements during survey flights, ensuring razor-sharp images.

In order to have both cameras stabilized by the GSM 4000, a special adapter plate was designed, which features two pods that keep the cameras in an oblique view. and a Flight Management System. In parallel, an AIS receiver records which ships are moving in the vecinity of the aircraft. This is important because only off-shore data is recorded and the ship data can therefore be correlated with the airborne data.

“Thanks to the ultra-high-spec of our camera equipment and the GSM 4000, which ensures blur-free exposures, our aircraft will be flying at heights (1800 ft) that will not cause any disturbance to birds or marine megafauna while at the same time allowing us to collect the highest-quality digital imagery”, Sarah Kandrot added.

Thomas Risch, founder & lead of GALG International said: “We as Global Assistant & Logistic Group actively supported Green Rebel with the design of the equipment and the integration. As system integrator we always strive to keep the system as multi-purpose and scalable as possible. We have therefore chosen the GSM 4000, as it offers us the possibility to add further sensors (LiDAR, HySpex etc.), should this become necessary. In addition, we have many years of experience with the SOMAG devices and therefore know about their high quality.”

“In the run-up to the delivery of a fully equipped survey aircraft, the close interaction of a large number of players in the industry is necessary. We therefore always work closely behind the scenes with our long-term partners to ensure that the customer is satisfied with the final result. To ensure this, we provided fast and unbureaucratic support, whether it was answering (design) technical questions or providing a dummy device to ensure a smooth integration process”, Sören Lieske, Sales Manager of SOMAG AG Jena concluded.
