Fixed-Wing and VTOL UAV Platforms

EOS C VTOL Fixed-Wing Hybrid UAS

EOS-VTOL Hybrid Fixed-Wing Drone

The EOS C is a mini-class, electric fixed-wing drone with vertical take-off and landing capability, designed to deliver stable and clear imagery for tactical, government and commercial missions, especially those taking place under restricted and difficult terrain conditions.

The EOS C has a flight time endurance of three hours when operating in fixed wing mode; and two hours endurance when flying as a multirotor. The airframe can be instantly converted between fixed-wing and VTOL modes. The extremely low noise output and low visual footprint make it an ideal aerial platform for Special Operations Forces.

A fully gyro-stabilized two-axis EO/IR camera gimbal provides an HD video and imagery feed to a Ground Control Station with onboard recording, and an additional plug & play payload can be fitted for precision aerial mapping.

With an advanced autopilot providing automatic takeoff, landing and navigation between user-defined waypoints, the EOS C can even be launched from the deck of a rescue vessel or battleship. The highly flexible system is ideal for a wide range of military, government and commercial applications including battlefield reconnaissance, search & rescue, border patrol, mapping and surveying.

Gyro-Stabilized Drone Camera Gimbals

Shark Gimbal – Stabilized Dual-Camera UAV Gimbal

Dual Stalibilsed Drone Gimbal

Dual EO-IR UAV Gimbal

The Shark roll-tilt gyro-stabilized dual-camera UAV gimbal, suitable for both fixed-wing and multirotor aircraft, provides both electro-optic and infrared capabilities, streaming clear and stabilized live geo-referenced video back to base.  Advanced features include target tracking, geo-locking and moving object detection.

The dual-side design, with sensors on both sides of the stabilizing mechanism, allows the overall height of the gimbal to be extremely low, and the modular sensor mounts allow for quick, easy upgrades and payload changes. The gimbal can also be equipped with an optional IR illuminator and laser rangefinder for further functionality.

The Shark Stabilized Dual-Camera UAV Gimbal is available in a number of different configurations.
