Small Tactical UAV System


BAI’s Tern UAV system offers users an

affordable, compact tactical UAV capable of

performing a wide range of remote sensing,

precision dispensing, or other aerial robotic

applications requiring reliable performance,

low operating cost, and ease of use.

The Tern aircraft is constructed of sturdy

composite materials and features a proven

versatile hi-wing design with excellent

ground clearance that allows operation from runways

and semi-improved surfaces. Generous flaps enable

short rolling take-offs and slow flight; electrically actuated

main gear disc brakes quickly decelerate the aircraft

after touchdown, allowing short-field landings. A trailermounted

pneumatic launcher is available to enable

launching in tactical conditions.

Tern’s quiet 100cc 2-stroke engine burns a conventional

gas/oil mixture. Fuel for four-hour’s flight is contained in

the aircraft’s fuselage tank; optional external tanks may

be fitted to gain additional capacity. Aircraft and payload

are powered by onboard batteries.

Tern employs BAI’s Generation III GPS Autopilot that

fully controls air vehicle heading, altitude, airspeed, and

GPS waypoint navigation. A 10-watt video/telemetry

microwave datalink transmits real-time imagery and

vehicle telemetry back from the aircraft at ranges up

to 50km.

Switchable forward and side-looking color TV cameras

are standard, and Tern comes fitted with connections and

mounting that easily accept an optional BAI Pan-Tilt-Zoom

Daylight Color TV or Pan-Tilt IR payload. Tern may also

be easily reconfigured to accept many other types of

equipment, such as communications jammer or relay

packages or -INT payloads.

The Tern system’s Ground Control Station is available

in “Table-Top” or “Shelter-Mounted” configurations that

both feature a microwave receiver, amplified uplink

transmitter, and a rugged laptop computer with easy-to-

use software that makes mission planning simple and

which allows the Tern aircraft to be re-tasked while

airborne. BAI’s modular GCS also features durable rackmount

construction and operation on 12 or 110-volts.

Aircraft and Payload Controllers are provided, as is a

video recorder and a built-in crew communications

system. In addition to many standard features, several

equipment options are also available for the GCS,

including a heads-up display of flight data, auto-tracking

antenna array, and remote video terminal.

The Tern system is easily deployed: typically a crew of

only three or four are required for set-up, operation, and

maintenance. The Tern aircraft breaks down in minutes

into a few easy to handle components which quickly pack

into the supplied hard-shell transportation and storage


A complete Tern system can be user-defined and

typically includes several aircraft, onboard sensors, one

or more ground control stations, field support equipment,

and a complement of spare parts. Factory support,

including training, payload integration, and onsite flight

services, are available separately as required.
