SaudiGeoSat 1/HellasSat 4

NSSDCA/COSPAR ID: 2019-007A

Description

The first satellite to be deployed was the upper passenger on the stack, the Saudi Geostationary Satellite 1/Hellas Sat 4, also called HS-4/SGS-1.

This is a dual payload geostationary condosat for KACST (King Abdulaziz City for Science and Technology– Saudi Arabia) and Hellas Sat (Greece – Cyprus).

With a mass of 6,495 kg, HS-4/SGS-1 will provide telecommunications capabilities, including television, Internet, telephone and secure communications in the Middle East, South Africa and Europe.

The Saudi Geostationary Satellite 1 communications payload will provide advanced Ka-band spot beam communications services for the Kingdom of Saudi Arabia’s KACST, including secure communications for the Gulf Cooperative Council region. KACST is an independent scientific organization of the government of Saudi Arabia that is responsible for the promotion of science and technology in the Kingdom.

The Hellas Sat 4 communications payload, on the other hand, will offer advanced Ku-band regional beam communications services for Arabsat’s subsidiary Hellas Sat, a Greek-Cypriot satellite operator which provides services to leading Direct-to-Home (DTH) operators by delivering contents to more than 3 million households.

With a design life of more than 15 years with orbital maneuver up to 23 years, HS-4/SGS-1 will be positioned at 39° East and will join Hellas Sat 3, launched by Arianespace on June 28, 2017 from the Guiana Space Center (on Flight VA238).

Since the launch of Arabsat-1A in 1985, HS-4/SGS-1 will be the 22nd satellites orbited for the Middle East region, accompanying the development of middle-eastern space programs.
