The A2100 is a model of communications satellite spacecraft made by Lockheed Martin Space Systems.
[5] Other A2100 spacecraft include JCSAT-13 and VINASAT-2, which were launched May, 2012 on an Ariane 5 rocket,[6] as well as Arabsat-6A and Hellas Sat 4/SaudiGeoSat-1 of Saudi Arabia's Arabsat-6G program.
[9] The A2100 satellite system was developed by the Astro Space team at its East Windsor, New Jersey facility, with team members delivering a flexible common bus with fewer components, lower spacecraft weight, and reduced customer delivery time.
[11][12] The attitude control system includes reaction wheels,[13] with momentum desaturation and main motor maneuver attitude control propulsion provided by small monopropellant hydrazine motors.
This hydrazine supply is contained in a central propellant tank of 0.90 m diameter and up to 2.00 m length depending on the customer's requirements.
