level for the kids) to $1,500 (advanced
level for the hobbyist). They are operated via a smart phone or a hand-held
controller over a fairly short range (from
a few hundred feet to less than 8 miles,
depending on the system) at very low
altitude, and they are usually equipped
with a commercial digital camera that
can provide video or still frames (known
as first person view or FPV) to an operator on the ground.
In order to make them cheap and
easy to use, the datalinks and navigation systems are pretty standard. Typical frequencies for control, telemetry
and video links are 433 MHz, 900-915
MHz, 1.3 GHz, 2.4 GHz and 5.8 GHz.
Some systems also feature GPS-aided
navigation, allowing the UAV to fly to
pre-programmed waypoints. GPS navigation also enables an automatic "return to home" (RTH) function, a signal
that can be activated manually by the
operator or automatically if the command link is temporarily lost or if the

drone's battery is about to quit, for
instance. The RTH function sends the
drone back to the location where its
flight originated.
For commercial mini-drones, there
are many electromagnetic vulnerabilities that can be exploited, depending
on the scenario. Tactics includes jamming and then taking over the UAV's
command link, after which it can be
landed safely, crashed into the ground,
sent up to a higher altitude where it
will be beyond the range of its original
command link. As mentioned earlier,
the command signal from the ground
control device can be detected and followed back to the UAV operator. Another option on more sophisticated
mini-drones is to activate its RTH command and follow the drone back to its
operator. The drone's video link can
also be intercepted during this RTB
activation, allowing law enforcement
officials to identify the drone operator in real-time (i.e., the surprised-

looking guy with the remote control in
his hands).

COUNTER-UAV SOLUTIONS
As UAVs have proliferated from military air vehicles to smaller commercial
drones, the defense industry has developed solutions accordingly to defeat
"low, slow and small" drones.
At DSEI in London last month, two
companies announced new counter-UAV
systems designed to attack commercial
mini-drones. Selex ES introduced its Falcon Shield counter-UAV system, which
integrates a number of the company's
systems into a single counter-UAV solution. Falcon Shield's sensor suite comprises up to three IR and RF sensors for
target detection and tracking. The system typically detects UAVs via a compact
360-degree radar, which can be selected
to suit a specific environment, such
as a wide-open area or an urban canyon presents limited field of view and
multi-path challenges. After detection,
