DST Control

Gyro stabilized EO/IR gimbal systems and lightweight thermal imagers for UAVs

Located in Linköping, Sweden, DST CONTROL supplies light-weight, high performance gyro-stabilized electro-optical systems with both EO and IR capabilities, and small light-weight thermal imagers.

DST Control UAV Gimbals

OTUS Gyro-stabilized Sensor Systems

OTUS gyro-stabilized electro-optical micro-gimbals are optimized for use in small & medium sized unmanned vehicles and small manned aircraft, featuring a day-light camera and/or an un-cooled infrared camera combined with a laser range finder. OTUS is one of the smallest and lightest gimbals on the market, yet provides performance & functions typically only found in much larger units.

The two axis OTUS U135, L170 and L205 gimbals reach a new level of stabilization performance thanks to purpose-built high-bandwidth torque motors implementing active vibration attenuation. The all new four axis OTUS U-250 gimbal achieves even greater stabilization due to a combination of purpose-built high-bandwidth torque motors and geared motors.

DST Control UAV Gimbals

All electronics required for the advanced digital control fits within the unit shell of each gimbal. The user only has to connect an external power supply, a video monitor and a joystick, to have the system up and running. A three dimensional micro-mechanical IMU and a laser range finder mounted directly on the optical bench, allows for advanced features like geo-location and geo-positioning, provided an external heading source is connected to the gimbal. Each gimbal features a powerful digital servo controller, which is even capable of providing enough computational power to drive optional features like vehicle control and navigation.

OTUS provides unique optional functions such as geo-localization, automatic video tracking and video recording, with everything integrated within the gimbal. The OTUS gimbals have no export restrictions, nor ITAR. As a trusted & established supplier of components and know-how for the unmanned vehicle industry for the last 20 years, DST has been involved in several national and international unmanned aerial vehicle projects.
