Providing strategic ISR with a VTOL tactical footprint

Koios is a S2 class fully autonomous (in take-off and flight) VTOL UAV, with a 4m wingspan, a payload of 7kg (including fuel) and an MTOW of 35kg. Koios is fully runway independent and can take off and land vertically autonomously using 8 brushless electric motors. Transitioning to forward flight, Koios is powered by an efficient 4-stroke multi-fuel engine capable of running on most heavy fuels for safety and availability, including Jet A1, kerosene, gasolene and SAF.

Koios can be operated by a crew of two personnel; the platform disassembles for storage in two packing boxes that allow for ease of transport. The two operators can unpack and assemble Koios, conduct pre-flight checks and launch in under 10 minutes. Koios and Fregata platforms share 90% commonality of components which eases the burden of training and maintenance.

Ground Control System (GCS) in action

The GCS consists of a minimum of two ruggedised laptops, providing a live feed to the Internal Pilot in command of the UAS. Although Koios navigates fully autonomously, the IP has full authority over the aircraft via the user-friendly SC3 graphical interface, to send flight commands to the aircraft as well as receiving a live data feed of the heading, altitude, location, speed and avionics/engine status. The Payload Operator receives a live feed of the fitted payload(s) and has full operation of the gimbal and EO/IR camera.

The GCS enables the selection of waypoints of interest either using a mouse or by using the touch screen to place waypoints using a ‘drag and drop’ method commonly used by touch screen devices.

The GCS is highly portable and can be operated from locations convenient to the end user e.g. from the back of a pick-up truck or situated in a fixed command centre.
