GSM 4000


The GSM 4000 is the flagship of the airborne product line and was developed for large format sensors. SOMAG‘s largest three axes gimbal is extremely powerful with a payload up to 120 kg. The control panel on top of the mount guarantees user-friendly handling. The USB port allows you to connect the device with the SOMAG Mount Control App.
