Arabsat-6A is a geostationary communications satellite operated by Arabsat.[4] The satellite was built by Lockheed Martin Space Systems on a modernized A2100 bus.[5] The satellite was successfully launched from Kennedy Space Center LC-39A aboard Falcon Heavy on April 11, 2019.[6][7]

History[edit]

Arabsat-6A and SaudiGeoSat-1/HellasSat-4 are the two satellites of the Arabsat-6G program, ordered by the Arab League to supply the communications needs of member states.[8] Contracts to build the two satellites were awarded to Lockheed Martin Space Systems in April 2015. In September 2015 Arabsat awarded the launch contract for Arabsat-6A to SpaceX for a Falcon Heavy flight with no expendable boosters.[9]

Spacecraft[edit]

Arabsat 6A is based on an updated version of the A2100 bus and is considered among the most advanced communications satellites built.[10] The spacecraft utilizes fixed and steerable Ku-band and Ka-band transponders to provide TV and radio services to the Middle East and North Africa from its station at 30.5°E.[11]

Launch[edit]

Arabsat-6A was launched aboard the first operational Falcon Heavy on 11 April 2019 at 22:35 UTC from Kennedy Space Center LC-39A.[6] Following a successful launch, the twin side boosters separated from the center core and returned to land at Landing Zones 1 and 2, while the center core completed its mission and landed on Of Course I Still Love You. Approximately 34 minutes after launch, the Arabsat-6A was released from the second stage and began a 17-day process to reach its operational orbit.[11]
