HellasSat 4/SaudiGeoSat 1

HellasSat 4/SaudiGeoSat 1 (A2100 upgraded) [Lockheed Martin]

HellasSat 4/SaudiGeoSat 1 is a Greek geostationary communications satellite for Hellas Sat, which is owned by Arabsat.

Arabsat and King Abdulaziz City for Science and Technology (KACST) announced in April 2015 contracts for Lockheed Martin to manufacture two A2100 communications satellites - Arabsat 6A and HellasSat 4/SaudiGeoSat 1. The contracts were signed April 9, 2015. Construction of the satellites will commence immediately and will be completed for launch in 2018.

The satellite will be built on a modernized version of Lockheed Martin's A2100 bus, which builds on that flight-proven design with advanced innovations including propulsion, solar arrays and electronics.

Hellas-Sat-4/SaudiGeoSat-1 will be located at 39 East. The satellite is designed for a 15-year service life, and will be manufactured in Denver, Colorado.
