Advanced Features and Applications

DSG Modules: All DSG pan-tilt units provide a complete integrated solution for ultra low-cost gyro-stabilization of various payloads for sea, air and ground applications. Inertial Line of Sight stabilization allows thermal and video cameras to stay on target while in transit. The Dual-Axis Stabilization Gyroscope modules offer real-time user-controlled stabilization by implementing advanced closed-loop control methods. The DSG modules provide impressive performance at entry-level costs, while maintaining high accuracy in stabilize and track applications. Built-in all DSG modules is an intelligent system that offers direct payload pointing at precise latitude, longitude and altitude geo or GPS coordinates. The DSG modules can accept geo-coordinates through the built in RS-232 or Ethernet/IP host interface and aim the payload to the corresponding location. Automatic pointing of the payloads simplifies system integration and allows efficient control and configuration of all pan-tilt functions.

Multiple mounting options: All Hellenic Instruments pan-tilt units offer user-configurable mounts, allowing for easy integration of payloads. With multiple mounting brackets and options, different types of payloads can be secured on the platform, resulting in a precisely balanced system.
