Hellas-Sat Consortium Ltd. (Hellas-Sat) is the owner and a wholesaler of capacity and services of the Greek/Cypriot Hellas-Sat-2 satellite which was launched successfully on 13 May, 2003 to the 39°E orbital position in the Geostationary Satellite Orbit. The Hellas-Sat-2 satellite is controlled via two proprietary TT&C stations located in Greece and Cyprus. In 2013 Hellas-Sat was acquired by Arabsat.

Hellas-Sat has developed a network of strategically located teleport partners with DVB platforms, carrying over 100 television channels, and IP-based services through its two fixed beams over Europe, and two steerable beams over the Middle East and South Africa. It offers high-power, direct-to-home transmissions as well as occasional video feeds and Internet access services.


HellasSat was founded in 2001 and is a subsidiary of Hellenic Telecommunications Organization (OTE S.A.), the biggest telecommunications provider in south-eastern Europe.

On May 13th 2003 Hellas-Sat 2 satellite was launched and has an expected lifetime of 15 years.

In February 2013 Saudi Arabia based Arabsat purchased a 99% stake in Hellas-Sat from OTE for 208 million plus 7 million euros in dividends. Hellas-Sat was Arabsat’s first major acquisition.

In June 2015 satellite manufacturer Thales Alenia Space and satellite operators Inmarsat and Hellas-Sat agreed on the construction of a powerful satellite, the Inmarsat S / Europasat / Hellas-Sat 3. The satellite will provide Mobile Satellite Services (MSS), Fixed Satellite Services (FSS) and Broadcast Satellite Services (BSS).

The MSS payload is designed to deliver an S-band service across all 28-member states of the EU; the FSS/BSS coverage zones are Europe, Middle East and Southern Africa. The Inmarsat S / Europasat payload will offer enhanced mobile services across Europe through a hybrid network, which combines S-Band satellite services with a Complementary Ground Component (CGC) infrastructure. Inmarsat S / Europasat will serve the aviation passenger connectivity services, as well as the safety services for Public Protection & Disaster Relief (PPDR) all over Europe. The Hellas-Sat 3 payload will deliver DTH and Telecom services in its designated coverage areas, maintaining and expanding Hellas-Sat business reach with additional capacities.

Built on the Spacebus 4000 C4 platform from Thales Alenia Space, Inmarsat S / Europasat / Hellas-Sat 3 will deliver a multi-beam mission in S-band and Ka-band for Inmarsat as well as a powerful Ku/Ka-Band mission of 44 Ku and 1 Ka transponders for Hellas-Sat. The satellite will weigh about 5.9 tonnes at launch and will offer payload power of about 12.3 kW. Inmarsat S / Europasat / Hellas-Sat 3 will be positioned at 39° East.

In March 2017 start-up company Global IP Cayman made an agreement with Hellas-Sat to operate their new GiSAT-1 satellite. The agreement has duration of 15 years, regardless of the life expectancy of the satellite. GiSAT-1 satellite will be controlled from Greek and Cypriot control centers and Teleports by Hellas-Sat engineers.
