The Gyro Stabilization Mount GSM 4000 is the successor of the world renowned GSM 3000 and the flagship of SOMAG AG Jena’s airborne Gyro Mount line.

Advantages

Industry standard
for large format cameras and scanners
Highest payload stabilization
of SOMAG Airborne Gyro Stabilization Mounts
Highest stabilization accuracy
of SOMAG Airborne Gyro Stabilization Mounts

Full Covered Hydraulic System

The Gyro Stabilization Mount 4000 is designed to automatically stabilize airborne cameras, scanners, LiDARs and other imaging sensors. The Mount’s hydraulic gimbal system is equipped with four cylinders and two servo pumps to compensate for drift, roll and pitch movement in real-time for the best possible data acquisition quality. The gimbal ensures perfectly aligned and pin-sharp images. With a residual deviation from perpendicular of
≤ 0.02° rms (with IMU support) the 3-axis gimbal offers the highest stabilization accuracy of SOMAG’s airborne gyro mount line.

Industry standard for large format sensors

Designed for large format sensors, the GSM 4000 has become industry standard for payloads up to 120 kg. Due to its versatility, the GSM 4000 can stabilize a wide range of modern surveying and surveillance sensors and is not limited to any specific set of hardware. This makes the GSM 4000 a perfect add-on device for your applications.

The modern control panel on top of the Mount allows intuitive manual control of the device, mode of operation change and visualization of the device status. The standard scope of delivery of the GSM 4000 includes a Passive Vibration Isolation Ring (PaVIR) which aims to decouple high frequency oscillations. Select between 8 different ring configurations and get the PaVIR that exactly matches your sensor weight.

Applications

For precise airborne surveying and blur-free images taken from above, they have become indispensable and an established part of the overall equipment: Gyro Stabilization Mounts. Installed into the fuselage of aircraft, they compensate for its roll, pitch and yaw movements to keep the sensor in a leveled position. Would you like to see how SOMAG customers benefit from their Mounts? We have compiled a series of application examples for you that show the diversity of application scenarios for our devices.

Why Customers

Trust Somag

“The GSM4000 is an excellent stabilization platform, which is ideally suited for the fully integrated RIEGL airborne laser scanner systems VQ-1560II-S, VQ-880-GII, as well as for the airborne laser scanners VQ-480II and VQ-580II with external IMU/GNSS system and up to two digital medium format cameras.

The use of the GSM4000 in the field of airborne laser scanning enables not only the regular distribution of measurement points on the ground, but also results in a significant increase in efficiency when flying over large areas by reducing the required overlap of neighboring scan strips.”

Peter Rieger, Manager RIEGL Airborne Laser Scanning Business Division

“We integrated our sensors with Somag’s GSM product line in 2014. We’ve since offered numerous GSMs with our high performance hyperspectral and thermal imaging systems. Somag products have consistently met our stabilization requirements. The team at Somag are very professional, responsive and supportive of our needs.”
