Ruggedized Stabilization Mount

RSM 50 - Marine

The compact Ruggedized Stabilization Mount 50 targets the acquisition of perfectly stabilized offshore data.


  • Compact and lightweight design

    suitable for deployment on USVs and small buoys
  • Adaptable to operational requirements

    upside-down hanging application possible
  • Most cost-effective marine Gyro Mount

    suitable for entry-level users

Better data with cost-effective gyro stabilizer

The RSM 50 is the smallest and most cost-effective of SOMAG’s marine gyro stabilizers. The ruggedized platform compensates roll and pitch motions of boats and ships moving in wavy waters. The two-axis gimbal boasts an innovative round shape, a small form factor and low weight suitable for capturing highly accurate footage even on smaller buoys and on ASVs/ USVs for unmanned missions. High quality materials and a solid mechanical design ensure an effective use of this salt- and splash-water resistant gyro mounting system.

Precisely adaptable to your needs

The electromechanical gyro stabilizer ensures highly accurate data capturing with electro-optical reconnaissance and surveillance camera systems up to 40 kg (88.2 lbs). No matter which payload is combined with the Mount, the result is always the same – the Mount load remains perfectly balanced, even when the ground is moving.

The RSM 50 can be adapted to your specific application requirements, including upside-down hanging installation. In addition, the successor of the RSM 400 now also offers an energy-saving mode for long-term applications as well as a failsafe braking system to securely lock payload during power outage. The new Ethernet communication interface allows for an integration into existing networks as well as a control and monitoring of multiple mounts within a network.

Preliminary data, subject to change

1 Vehicle angular motion ≤± 18° / 25°/s / 40°/s2 – small periodical lateral accelerations (≤ 0.5 g) acceptable; constant lateral accelerations for more than 1 minute resulting from vehicle’s turning maneuvers are compensated by internal or external GPS input. No GPS input could reduce the performance of the Mount during turning maneuvers.
2 Possible payload weight depends on lateral acceleration and CoG of payload | shown data is based on 1.0 g lateral acceleration and a CoG payload offset to the Mount surface of: 125 mm (4.9 in) | 200 mm (7.9 in) | 400 mm (15.7 in)
3 Maximum duration 90 s at 55 °C surrounding temperature / longer if temperature inside the unit is < 55 °C
4 Horizontal payload CoG offsets are not considered; without wind force and other possible external forces


Sharp images and a stabilized field of view despite high waves and rough weather conditions? The solution is Gyro Stabilization Mounts, developed especially for this purpose. Roll and pitch movements are reliably compensated to keep the sensor system perfectly balanced. Would you like to see in which cases SOMAG Marine Mounts are beneficial? We have compiled a number of examples for you that show the variety of application scenarios for our devices.

Why Customers

Trust Somag

We used the RSM 400 on the upper deck of a research vessel during the field tests of the project ACTRESS – Architecture and Technology Development Platform for Realtime Safe and Secure Systems project (duration 3 years), funded by the Federal Ministry for Economic Affairs and Energy under grant no. 03SX448. Up to a wave height of approx. 1.5 m, the Mount ensured to a high standard that our Riegl laser scanner VZ2000i was stabilized and we were thus able to obtain laser scans of traffic situations at close range as part of collision prevention measures. We chose a SOMAG RSM 400, because the dimensions and technical data of the Gyro Mount have been impressive. The overall impression was very convincing. The Mount worked reliably and compensated for the ship’s movements in real time.
