FLEET
XTAR's fleet is comprised of two satellites, 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 Unmanned Aerial Vehicles (UAV’s).
Both satellites are based on the Space Systems/Loral (SS/L) flight-proven 1300 spacecraft. The 1300 is a decades-proven, modular platform that provides a foundation for continual evolutionary development to deliver increasingly higher power, greater flexibility, and longer mission life. In 2010 the SS/L fleet of more than 60 GEO spacecraft based on the 1300 platform had 99.999 percent on-orbit availability.
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. XTAR-LANT’s 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.
OPERATIONAL REACH
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.
