MEETING THE NEEDS OF TODAY'S WARFIGHTERS
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 and intelligence agency-specific communications services to U.S. and Allied government agencies and military services to support and augment government-owned "war fighting" space assets.
The XTAR system is also MAC I compliant.
XTAR meets a continuing and growing need of today's mobile forces, providing wideband services that are cost-effective and support high intensity operations where bandwidth is a key ingredient to success. These services support rapidly deployable forces needing near real-time provisioning of SATCOM services and provide mobile and agile combat teams with high capacity bandwidth into small terminals.
XTAR's fleet is comprised of XTAR-EUR and XTAR-LANT, operating in the X-band frequency range of 7.25-8.4 GHz. The system provides overlapping coverage with regional redundancy for increased service and reliability.
XTAR can accommodate massive wideband data requirements with its global, fixed, and steerable beams and high-powered 72 MHz transponders. The bandwidth is not application-specific: XTAR's capacity can support and transmit to any one of the primary architectures used by government agencies today, including fixed-to-fixed, tactical-to-tactical, reach-back, broadcast and airborne platforms.
Both satellites are based on the Space Systems/Loral (SS/L) flight-proven 1300 spacecraft. The 1300 is a decades-proven, modular platform that gives XTAR’s customers maximum flexibility and reliability. XTAR’s fleet offers MAC I level support to mission critical operations.
Approximately one third of SS/L's 1300 spacecraft have operated beyond their contracted lives. Both XTAR satellites are designed for 18-plus years of on-orbit operation.
XTAR-EUR 29° E
XTAR's first satellite, XTAR-EUR, was launched in Feb 2005 and began service in April 2005. It provides X-band coverage over a wide geographic region from Eastern Brazil and the Atlantic Ocean, across Europe, Africa, the Middle East, South East Asia and as far east as Singapore. The extremely flexible payload is delivered through its two global, one fixed, and four steerable spot beams which can be relocated anywhere within the satellite's coverage area.
XTAR-LANT 30° W
With its March 2006 launch, XTAR-LANT enabled XTAR to offer X-band services in North America for homeland security applications as well as one-hop connectivity to Europe and the Middle East. The XTAR-LANT payload is extremely flexible. It covers a large geographic area with its two global beams, one fixed spot beam over the Eastern U.S., and three spot beams that can be relocated anywhere within the satellite's coverage area. This flexibility, combined with XTAR-EUR's coverage in Asia, makes both payloads compatibility with WGS and adds tremendous capabilities for government and military users alike.
XTAR's global and high-power spot beams and extensive reach provides numerous operational combinations to meet the most demanding military, intelligence or civil government requirements.
