Small Tactical UAV System<br />
<strong>TERN</strong><br />
BAI’s Tern UAV system offers users an<br />
affordable, compact tactical UAV capable of<br />
performing a wide range of remote sensing,<br />
precision dispensing, or other aerial robotic<br />
applications requiring reliable performance,<br />
low operating cost, and ease of use.<br />
The Tern aircraft is constructed of sturdy<br />
composite materials and features a proven<br />
versatile hi-wing design with excellent<br />
ground clearance that allows operation from runways<br />
and semi-improved surfaces. Generous flaps enable<br />
short rolling take-offs and slow flight; electrically actuated<br />
main gear disc brakes quickly decelerate the aircraft<br />
after touchdown, allowing short-field landings. A trailermounted<br />
pneumatic launcher is available to enable<br />
launching in tactical conditions.<br />
Tern’s quiet 100cc 2-stroke engine burns a conventional<br />
gas/oil mixture. Fuel for four-hour’s flight is contained in<br />
the aircraft’s fuselage tank; optional external tanks may<br />
be fitted to gain additional capacity. <strong>Aircraft</strong> and payload<br />
are powered by onboard batteries.<br />
Tern employs BAI’s Generation III GPS Autopilot that<br />
fully controls air vehicle heading, altitude, airspeed, and<br />
GPS waypoint navigation. A 10-watt video/telemetry<br />
microwave datalink transmits real-time imagery and<br />
vehicle telemetry back from the aircraft at ranges up<br />
to 50km.<br />
Switchable forward and side-looking color TV cameras<br />
are standard, and Tern comes fitted with connections and<br />
mounting that easily accept an optional BAI Pan-Tilt-Zoom<br />
Daylight Color TV or Pan-Tilt IR payload. Tern may also<br />
be easily reconfigured to accept many other types of<br />
equipment, such as communications jammer or relay<br />
packages or -INT payloads.<br />
The Tern system’s Ground Control Station is available<br />
in “Table-Top” or “Shelter-Mounted” configurations that<br />
both feature a microwave receiver, amplified uplink<br />
transmitter, and a rugged laptop computer with easy-to-<br />
Shelter Mounted<br />
Ground Control<br />
Station<br />
use software that makes mission planning simple and<br />
which allows the Tern aircraft to be re-tasked while<br />
airborne. BAI’s modular GCS also features durable rackmount<br />
construction and operation on 12 or 110-volts.<br />
<strong>Aircraft</strong> and Payload Controllers are provided, as is a<br />
video recorder and a built-in crew communications<br />
system. In addition to many standard features, several<br />
equipment options are also available for the GCS,<br />
including a heads-up display of flight data, auto-tracking<br />
antenna array, and remote video terminal.<br />
The Tern system is easily deployed: typically a crew of<br />
only three or four are required for set-up, operation, and<br />
maintenance. The Tern aircraft breaks down in minutes<br />
into a few easy to handle components which quickly pack<br />
into the supplied hard-shell transportation and storage<br />
container.<br />
A complete Tern system can be user-defined and<br />
typically includes several aircraft, onboard sensors, one<br />
or more ground control stations, field support equipment,<br />
and a complement of spare parts. Factory support,<br />
including training, payload integration, and onsite flight<br />
services, are available separately as required.<br />
