The A2100 is a communications satellite spacecraft made by Lockheed Martin Space Systems for telecommunications in geosynchronous orbit.

The Lockheed Martin A2100 geosynchronous spacecraft series is designed for a variety of telecommunications needs including Ka band broadband and broadcast services, fixed satellite services in C-band and Ku band payload configurations, high-power direct broadcast services using the Ku band frequency spectrum, and mobile satellite services using UHF, L-band and S-band payloads.[1]

The A2100 satellite system was developed by a Skunk Works team at the Astro Space East Windsor, New Jersey facility. A group of Space Architects, including Brian Stewart, John Close, Pete Wise and Keith Davies delivered a flexible common bus with substantially fewer components, lower spacecraft weight, and reduced customer delivery time. Jim Wilson led a team from GE's corporate R&D lab located in Niskayuna, NY, which helped with several technology underpinnings which advanced the A2100 design.

The first A2100 satellite, AMC-1, was launched September 8, 1996, and has already achieved its 15-year design life of on-orbit service. Since 1996 over 37 A2100 based satellites have been launched, with over 325 years of total on-orbit service. The most recent A2100 spacecraft, BSAT-3c/JCSAT-110R, was successfully launched Aug. 5, 2011. [2]

Lockheed Martin's highly reliable A2100 telecommunications satellite series has received several industry awards for reliability in its history, including Frost and Sullivan's Satellite Reliability Award for excellence in the production of flexible and reliable communications satellites used in geosynchronous Earth orbit.[3][4]

The A2100 series is modular and can be configured in different sizes:

  • A2100A = 1 to 4 kW
  • A2100AX = 4 to x kW
  • A2100AXS: enhanced A2100AX
  • A2100AXX : stretched version for mobile communications
  • Additionally there is an A2100M version, which fulfills military requirements.
