Fregata is a S2 class, pneumatic catapult launch and skid landing Intelligence, Surveillance, and Reconnaissance (ISR) platform with a 4m wingspan, a payload of 12kg (including fuel) and an MTOW of 35kg. With an extended endurance of 8-12 hours and a data link range of up to 190km, Fregata is highly capable and operationally flexible. Fregata is powered by an efficient 4-stroke multi-fuel engine which runs on most heavy fuels for safety and availability, including Jet A1, kerosene, gasolene and SAF.
The platform can be easily manoeuvred by two people, packed in lightweight carry cases and transported by a medium wheelbase van or truck. The platform is launched from a catapult by a team of three operators including a pilot, a launch commander, and an individual to load and monitor the catapult. Fregata and Koios platforms share 90% commonality of components which eases the burden of training and maintenance.

SC3
Mission Management System
Enhanced payload capacity
Fregata can carry a greater variety of payloads making it suited to an array of mission profiles.
Wet Wing
Internal fuel tanks maximise free space in fuselage for additional components.
Removable wings and tail
When disassembled Fregata can be transported in two packing boxes. When unpacked Fregata can be pre-flight checked and launched in under 10 minutes.
Lightweight skids
Allow for conventional landing on almost any unprepared surface.
Alternator
Alternator powers aircraft systems.
Multi-Fuel Engine
35cc 4 stroke capable of running on a wide range of fuels including Jet A1 and gasoline.
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.
