Nautical / Nimble Gyro Stabilization Mount NSM 500

SOMAG announces the launch of the new NSM 500, a medium-sized Gyro Mount between the smaller RSM 50 and the larger OSM 5000. With the launch of the NSM 500, SOMAG has now advanced all three devices of the marine and land product line to series 5.

Reliable Gyro Stabilization for Surveillance Sensors

The NSM 500 was primarily designed for the stabilization of surveillance sensors on medium to large maritime vessels and on mobile ground vehicles. Non-stabilized systems follow the movement of the water caused by the swell or the movement of the vehicle driving over uneven terrain, 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 or vehicle. This allows EO/IR systems to scan their environment without interference even in extreme sea and land conditions, in order to best detect, track and classify asymmetric air and surface threats. The NSM 500 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 or mobile land vehicles of land forces.

Reliable stabilization performance proven in long-term test

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.

High-density LiDAR and high-resolution imagery collection with Gyro Stabilization Mount GSM 4000 for flood study

Cooper Aerial Surveys was contracted by Helm Engineering to provide aerial lidar mapping of the Pahrump site for a flood study over the entire Nye County. Pahrump is a town located at the southernmost tip of Nye County, Nevada, about 62 miles (100 km) west of Las Vegas, adjacent to the Nevada–California border. The results of this survey help mitigate flood damage for existing and future projects.

Cooper Aerial Surveys uses a multi-sensor aerial system stabilized by a single SOMAG Gyro Stabilization Mount GSM 4000 to obtain the highly accurate lidar and aerial imagery data. The Mount helps to hold the sensors in place and compensates for movement as the aircraft moves down the flight line or crabs, ultimately resulting in crystal clear aerial imagery and even better quality data being captured for the entire mapping project.

GSM 4000

Advantages for Lidar and Imagery Products

  • Crystal clear aerial imagery

    through precise sensor stabilization during flights
  • Saving of time and money

     time spent on aerial triangulation can be reduced by 20%
  • Flexibility and compatibility

    GSM 4000 is adaptable to any sensor and camera system

To complete the project, Cooper Aerial collected 10cm GSD color imagery and 20 points per square meter LiDAR over the client-defined mapping limits. The project area covered roughly 171,000 acres (268 Sq Miles) of land. Aerial photography consisted of 31 flight lines with 2304 exposures, with a total of 523 mapping models.

The mapping data was used to compile a 1″ = 40″ stereo map to create all planimetric features and 3D Digital Terrain Model (DTM) for 1′ contour generation. Contour data was derived from LiDAR data and included major breaklines and hydro flattening.

By using the data collected by Cooper Aerial, Helm Engineering was able to create models to identify potential areas that were highly exposed to risks of flooding. Some of these hazardous areas contain high-end real estate communities worth several millions of dollars that need to be protected against these risks. Furthermore, this flood study allows the county to learn more about the impacts of a major flood event if preventative measures are not taken. Planimetric features included impervious surfaces (paved lots, roads, concrete), buildings, dirt roads, and drainage features. Cooper Aerial used the surface that was derived from the lidar data to create orthorectified photos, which were useful in the collection of planimetric features as well as quality control purposes.

Cooper Aerial is the largest firm in the Southwest, dedicated to providing leading edge aerial mapping solutions throughout the United States, Mexico, and Canada. To maximize time and cost efficiency without sacrificing the quality the customer expects, they use an integrated hybrid dual collection system consisting of a Teledyne Galaxy Prime Lidar and a Phase One 280 MP camera installed in a SOMAG Gyro Stabilizer GSM 4000 Mount.

This system enables a single mobilization of the lidar and camera in a seamless mission with only one aircraft, making the most of weather windows and generating matching data sets. This approach significantly minimized the project cost by about half of the flight cost, roughly $76,000. Without such a system, meeting the project deadline would have required mobilizing more aircraft or extending turnaround time.

Moreover, Cooper’s installation of the GSM 4000 provides it with clean data that is easier to process. This allowed the company to reduce the time required for aerial triangulation by 20%, which lowered the overall cost of the project for the customer.

Environmental testing

NSM 400 to successfully pass vibration test

SOMAG AG Jena has successfully completed vibration tests on its Nautical Gyro Stabilization Mount NSM 400 at the independent and accredited test laboratory MeßTechnikNord GmbH in Jena, Germany. The vibration test is part of a series of comprehensive environmental tests that the company performs at regular intervals, in addition to EMC, performance and other tests to ensure consistently high-quality standards for its devices.

Tests were carried out on the NSM 400 with its maximum payload of 100 kg (220.5 lbs) with a center of gravity of 250 mm above the mounts pivot point. The test aims to verify the mechanical strength of the Mount and to observe its dynamic behavior. Testing was carried out in accordance with IACS E10 No. 7 Vibration and DIN EN 60068-2-06.2008-10.

First, a sinusoidal sweep test was performed with a frequency range from 2 to 300 Hz. From 2 to 13 Hz the excitation amplitude equaled 1 mm, afterwards it depended on the acceleration of the shaker with 0,7g. The resonance test was run in all three space axes (x, y and z) and aimed to find the resonance frequencies of the Mount.

A total of 5 accelerometers (4 x single axis accelerometers and 1 x single accelerometer for control) were placed at the base plate, the top part and at the supporting structure of the stabilization platform to measure the resulting vibrations. In addition, a three-axis acceleration sensor was attached to the payload in order to measure the resulting vibrations there as well and thus incorporate the real use of the Gyro Mount with payload in the test.

“To meet the standard, it would have been sufficient to test the unit in non-operational mode. However, we wanted to go one step further and also test the mechanical-dynamic behavior of the mount in MAN and STAB mode. In all three scenarios the NSM performed just as desired,” explains Sebastian Schreiber, CTO at SOMAG.

After the resonance search the visual check was passed. There was no external damage and no visual deficiency after the test. The self-test via the SOMAG Mount Control App could also be performed successfully which was the success criteria for the test.

Since resonances with an amplification factor ≥ 2 were found in the sinusoidal sweep test, additional endurance tests (1.5 h each) were performed at each of these frequencies. The visual inspections after the endurance test did not reveal any damage or optical defects. The self-test via the Mount Control App could be performed successfully in all cases and the vibration tests were completed successfully overall.

SOMAG AG Jena has successfully tested the IP rating of its Gyro Stabilization Mounts for marine and land applications at the independent and accredited laboratory for environmental and materials testing at the Technologie-Zentrum für Oberflächentechnik und Umweltschutz Leipzig GmbH. The test of the protection class is part of a series of comprehensive environmental tests that the company performs at regular intervals, in addition to EMC and performance tests to ensure consistently high-quality standards for its devices.

Sebastian Schreiber, CTO at SOMAG, comments: “The mission of our marine and land gimbals is to flawlessly stabilize sensor systems in both marine environments with high humidity and salinity as well as in dusty, unpaved terrain. Therefore, they have been designed in such a way that neither dust nor water can enter into the units according to IP class 67.”

This classification has been successfully confirmed by recent tests according to DIN EN 60529: 2104 -09. The tests were carried out with an NSM 400, which was first placed in a dust chamber to test the protection against the ingress of solid foreign bodies (dust-tight). The NSM 400 was sprayed with talcum powder in the chamber from all directions. The talcum powder is very fine (<75 μm) and has rather lubricating properties. Due to the homogeneous structure of the dust, it infiltrates into the smallest joints, especially if negative pressure is applied, which was the case with the NSM 400. The gimbal was removed from the chamber and its functionality verified. Furthermore, the cover was removed and the device was opened. In accordance with the requirements for passing the test, there was no dust visible inside the unit.  

The second step was the test to determine the protection against temporary submersion. For this purpose, the NSM 400 was lowered into a dipping basin. The water level above the enclosure is defined with 1 meter. The gyro stabilizer remained submerged for 30 minutes. After this period, the Mount was lifted out of the basin, opened, and subjected to a visual inspection. No water was detected in the sealed area and the correct functioning of the device was confirmed.

    Offshore/Offroad Gyro Stabilization Mount OSM 5000

    SOMAG AG Jena announces the launch of the new OSM 5000, the most powerful gyro-based stabilization platform ever developed by SOMAG. With the launch of the OSM 5000 and the launch of the RSM 50, SOMAG introduces two gimbals of the new series 5 for industry-leading stabilization in offshore and offroad settings.

    High-class gyro stabilization for offroad and offshore environments

    The gyro stabilizer is equipped with high-precision built-in sensors to detect in real-time movements of land vehicles caused by rough terrain, as well as angular movements of boats, ships, Unmanned Surface Vessels (USVs), autonomous platforms and buoys caused by sea swell. The Gyro Stabilization Mount automatically compensates the movements to keep the sensor payload in a leveled position even when the ground is moving to provide razor-sharp imagery and comprehensive situational awareness. The IP class 67 weatherproof design allows the gimbal to do its job perfectly in humid, salty as well as dry, dusty environments.

    Two stabilization range configurations available

    “We offer the OSM 5000 in two different configurations, depending on the customer’s application, in order to do justice to the variety of possible use cases of our device and the resulting requirements,” says Sebastian Schreiber CTO, SOMAG AG Jena.

    With its symmetrical stabilization range, the Gyro Stabilization Mount compensates movements in roll and pitch up to ≤± 14.1°. This configuration is particularly interesting for customers who want to install their sensor on a land vehicle or floating support, since the general motion stimulation is rather symmetrical. However, if the OSM is to be installed on ships, the asymmetric configuration with ≤± 12.2° pitch and ≤±17.4° roll axis stabilization is recommended. As shown by studies on ship motions, motions in the roll axis pose greater challenges than in the pitch axis. Because ships are longer than they are wide, motions in the pitch axis are quite limited. In contrast, movements in the roll axis in sea state 6 can reach between 13° to 19°, depending on the width of the vessel1.

    1 Data is based on US Navy ship motion studies

    Most powerful gimbal ever developed by SOMAG

    The hydraulic gimbal system was designed to ensure precise leveling of heavy sensor payloads up to 300 kg (660 lbs) at only 55 kg own weight. Schreiber says: “When you consider the dimensions, it is quite amazing what we have created. With the OSM, we offer our customers a unit that can theoretically balance 4 grown men with an accuracy of ≤0.3°. The Gyro Mount is extremely powerful, but not monstrous. We clearly stand out from other devices on the market in terms of form factor, which has been kept as small as possible in relation to the performance of the Mount, being able to generate a peak dynamic torque of 550 Nm.”

    The OSM 5000 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 a network.
