Agencies providing defence and emergency<br />
services are increasingly reliant on mobile<br />
communications. Traveling rapidly over large<br />
areas, mobile units require real time, agile,<br />
communication systems for voice, data,<br />
image and video. Land systems must operate<br />
during all vehicle manoeuvres, and should be<br />
unaffected by the type of terrain encountered;<br />
airborne systems must operate in severe<br />
environmental conditions and meet demanding<br />
certification requirements. In order to meet<br />
these demands, Cobham has developed a<br />
family of <strong>Satcom</strong>-On-The-Move <strong>terminal</strong>s<br />
ensuring unequalled access to commercial<br />
and military satellites.<br />
The <strong>SPITFIRE</strong> <strong>low</strong> <strong>profile</strong> <strong>Ku</strong>-<strong>band</strong> <strong>terminal</strong> is<br />
designed for the most demanding land and<br />
airborne applications. The antenna’s <strong>low</strong> <strong>profile</strong><br />
and <strong>low</strong> mass make it suitable for installation<br />
on small business jets and UAVs, commercial<br />
and military aircraft and a wide range of land<br />
vehicles including HUMVEEs and SUVs.<br />
System description<br />
The highly integrated <strong>terminal</strong> includes the<br />
antenna, a 2-axis gear drive positioner and<br />
servo controller, an autonomous tracking<br />
receiver and an inertial navigation unit. A <strong>low</strong><br />
noise amplifier, block up and down converters<br />
and a high efficiency solid state power amplifier<br />
are also included, housed under a common<br />
radome above the deck.<br />
A simple L-<strong>band</strong> I/O and an RS232 interface<br />
together provide direct interface with<br />
standard modem systems, while also enabling<br />
control and monitoring of the system through<br />
a laptop computer.<br />
The operational schemes supported by<br />
<strong>SPITFIRE</strong> <strong>terminal</strong>s are SCPC and FDTDMA<br />
in star and mesh networks, DSSS multiple<br />
access and combined DSSS-TDMA (e.g. i-Direct)<br />
multiple access in star & mesh networks.<br />
Key features<br />
• Designed for both land<br />
and airborne applications<br />
• Increased data rates in<br />
transmit mode compared to<br />
equivalent circular reflectors<br />
• Low <strong>profile</strong> and <strong>low</strong> mass<br />
• Short acquisition and<br />
reacquisition time<br />
• Hemispherical coverage,<br />
with excellent RF<br />
performance at <strong>low</strong><br />
elevation scanning angles.
