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.

Titan VTOL/Multirotor UAV

KX4-LE VTOL Drone PlatformThe Titan is a long endurance, heavy-lift multirotor drone designed for ISR, search and rescue (SAR) and law enforcement missions. The multiple plug & play payload options provide enhanced situational awareness for rescue services and first responders.

Featuring VTOL functionality, the KX-4 LE UAS can be deployed quickly without the need for a runway or launch equipment; and the integral emergency parachute offers additional safety, especially when being operated in populated areas. The detachable boom arms and landing gear ensure the system can be easily packed away and transported.

The KX-4 LE UAS can be operated in fully autonomous or first-person view flight modes using a handheld or fixed Ground Control Station (GCS).
