Commercial satellite communications are critical to military
and government information dominance, and serve a significant
role in support of the Global Information Grid (GIG). The
XTAR system is designed specifically to provide customized,
defense-specific communications services to U.S. and Allied
government agencies and military services to support and augment
government-owned “war fighting” space assets.
In addition to U.S. and Allied governments and forces, the
XTAR system supports special operations and “comms-on-the-move”
for mobile command posts, small ships and airborne relay of
sensor data
Key features of the system include:
 |
Flexibility and Dynamic Mobility |
| |
XTAR provides high-powered satellite coverage whenever
and wherever it is needed. Troops and other users can
move their X-band spot beam coverage any distance required,
in real time. Whether for deployment of troops, vehicles
or vessels, XTAR’s spot beams can be dynamically
moved in real time to support long-haul communications,
logistics and infrastructure requirements and mission
critical needs.
|
|
Greater Bandwidth and Throughput |
| |
XTAR’s stackable spot beams and dual polarization
are capable of fulfilling large bandwidth requirements
and, if necessary, focusing substantial bandwidth in one
location, such as an active military theater. Its powerful
X-band transponders allow XTAR to provide more data throughput
to existing X-band terminals, even those smaller than
2.4 meters.
|
|
Fast Deployment and Global Interoperability |
| |
The XTAR system supports the unique delivery requirements
of multinational government, military and intelligence
communities, operating globally or in regional or small
theaters.
|
|
Backwards Compatibility |
| |
XTAR is specifically designed to interface with all
current X-band terminals without the need for additional
infrastructure requirements, thus significantly reducing
customer costs. The system supports higher data rates
with legacy X-band terminals.
|
|
Higher Performance |
| |
X-band transmissions are subject to lower rain and sandstorm
attenuation than Ku/Ka band transmissions, and the XTAR
satellites’ high power enables operations with smaller
tactical X-band terminals.
