SWARM<br />
Up to now, <strong>the</strong> limiting factor<br />
precluding remote-controlled<br />
swarming boat targets <strong>was</strong><br />
<strong>the</strong> requisite communications<br />
backbone to support such a<br />
large group of vehicles<br />
> Rock Gunnery School within <strong>the</strong><br />
Esquimalt base. Four operators each<br />
controlled four Hammerheads, with a<br />
‘mission comm<strong>an</strong>der’ co-ordinating <strong>the</strong><br />
entire flotilla. Relays of four Hammerheads<br />
were brought into a formation <strong>an</strong>d all<br />
followed pre-programmed waypoint<br />
navigation tracks.<br />
“Up to now, <strong>the</strong> limiting factor<br />
precluding such exercises has been<br />
<strong>the</strong> inability of establishing <strong>the</strong> requisite<br />
communications backbone that c<strong>an</strong><br />
support such a large group of vehicles,”<br />
says Fraser.<br />
“What used to happen <strong>was</strong> that in<br />
traditional comm<strong>an</strong>d <strong>an</strong>d control systems<br />
you would have <strong>an</strong> up link <strong>an</strong>d each vehicle<br />
would tr<strong>an</strong>smit back on a separate down<br />
link. One c<strong>an</strong> immediately see why <strong>an</strong><br />
old format system will not work for this<br />
type of exercise because you would need<br />
17 frequencies <strong>an</strong>d a 53-foot trailer full<br />
of radio equipment.” That, he adds, is<br />
assuming frequency approvals could even<br />
be obtained from national authorities for<br />
that m<strong>an</strong>y frequencies <strong>an</strong>d providing <strong>the</strong>re<br />

REVIEW | WINTER 2010<br />

Hammerhead is<br />

unm<strong>an</strong>ned surface<br />
vehicle target<br />
(USV-T) with <strong>an</strong><br />
award-winning<br />
surface-effect<br />
hull that is highly<br />
efficient in high<br />
seas at high<br />
speeds.<br />
The secret to being able to control so<br />
m<strong>an</strong>y vessels on a single half-duplex UHF<br />
frequency, says Fraser, is sophisticated<br />
multiplexing of <strong>the</strong> signal, using ultrarapid<br />
switching times between individual<br />
vessels—a world first from <strong>Meggitt</strong>, which<br />
has been working on <strong>the</strong> project for four<br />
years with support from <strong>the</strong> C<strong>an</strong>adi<strong>an</strong> Navy.<br />
A second unique feature of MTSC’s<br />
technical solution is building its system<br />
around <strong>an</strong> open st<strong>an</strong>dard—of increasing<br />
interest to customers. <strong>Meggitt</strong>’s UTCS is<br />
compli<strong>an</strong>t with NATO st<strong>an</strong>dard STANAG<br />
4586, a basic interoperability st<strong>an</strong>dard<br />
originally intended only for unm<strong>an</strong>ned air<br />
vehicles (UAVs) but which <strong>Meggitt</strong> has now<br />
exp<strong>an</strong>ded to h<strong>an</strong>dle unm<strong>an</strong>ned surface<br />
vehicles.<br />
As a result, says Fraser, “We’re now<br />
able to replicate with a high degree of<br />
fidelity one of <strong>the</strong> major asymmetric threats<br />
facing western navies today. We’ve already<br />
received several enquiries from several<br />
international customers asking how we<br />
m<strong>an</strong>aged to achieve this.” He adds that <strong>the</strong><br />
system is now deployed with <strong>the</strong> C<strong>an</strong>adi<strong>an</strong><br />
Forces <strong>an</strong>d that several navies w<strong>an</strong>t MTSC<br />

to report we did not snag a single pot <strong>an</strong>d<br />

Hammerheads “early next year” off<br />
