Space industry in Greece

Hellenic Space Centre

Chalandri, Greece government

The Hellenic Space Centre (HSC) is the national coordinating body for Greek space activities. It replaced the short-lived Hellenic Space Agency, a public limited company dissolved in August 2019, and is based in Chalandri, Athens. As a space agency, its core function is to develop and promote national capabilities in space technology and applications. This includes fostering domestic research and development, supporting the growth of a Greek space ecosystem, and representing Greece’s interests in international space collaborations. Currently, a primary focus of the HSA is supporting and participating in programs run by the European Space Agency (ESA). This suggests a strategy of building national expertise through collaboration with established European partners. While specific technologies are not detailed publicly, the agency’s activities inherently involve areas such as satellite communications, Earth observation, and potentially launch support or space-based infrastructure development as capabilities mature. Given its recent founding, the HSA is in the early stages of establishing a significant track record of independent missions or flagship projects. However, its role in coordinating Greek contributions to ESA programs indicates involvement in a range of ongoing European space endeavors. Details regarding specific customers are not publicly available, as the agency primarily serves a national coordinating function rather than directly offering commercial services. The Hellenic Space Agency uniquely positions Greece to actively participate in the growing European space sector and benefit from the economic and technological advancements it offers. By centralizing national space efforts, the HSA aims to establish a sustainable and innovative space industry within Greece, contributing to both national strategic interests and the broader European space landscape.

Hellas Sat

Athens, Greece commercial

Hellas Sat is an Athens, Greece-based GEO telecommunications satellite operator founded in 2001, operating as the Hellenic Republic's national satellite operator and a subsidiary of Arabsat (the Arab League's satellite consortium, which acquired majority ownership from Inmarsat in 2012) — providing Ku-band and Ka-band satellite capacity for direct-to-home (DTH) television broadcasting, broadband internet, VSAT enterprise networks, and government communications across a service area spanning Southeast Europe, the Middle East, North Africa, and South Africa. Hellas Sat's fleet centers on the Hellas Sat 2, 3, and 4 geostationary satellites positioned at 39°E longitude — a prime orbital slot for simultaneous coverage of the Balkans, Eastern Mediterranean, Middle East, and Sub-Saharan Africa, enabling the company to serve multiple distinct regional markets from a single orbital location. The 39°E position is particularly valuable for pan-European DTH broadcasting where satellite dish alignment for Southeastern European viewers makes it complementary to the dominant 19.2°E (Astra) and 13°E (Hot Bird) slots that serve Western Europe. The DTH broadcasting customer base includes Greek television broadcasters, regional pay-TV platform operators in the Balkans, and Middle Eastern TV distribution. Greek viewers have historically used Hellas Sat capacity for free-to-air Greek-language broadcasting, while the satellite's South African spot beams have supported VSAT enterprise connectivity and government networks in the region. Broadband VSAT services are delivered through small dish terminals for enterprise and SME customers lacking fiber access. Hellas Sat 3 (launched 2017, built by Thales Alenia Space on the Spacebus-4000 platform) added significant high-throughput Ka-band capacity and expanded the South African coverage footprint. The acquisition by Arabsat positioned Hellas Sat within the broader Arab satellite ecosystem, enabling capacity coordination with Arabsat's 26°E fleet and leveraging Arabsat's distribution channels across the Arab world. The company competes with Eutelsat at 7°W (West Africa), Intelsat at 34.5°W, and increasingly with Starlink's expanding enterprise service for remote site broadband.

Libre Space Foundation

Patras, Greece nonprofit

Libre Space Foundation, founded in 2014 and based in Patras, Greece, is a non-profit organization dedicated to the development of open-source hardware and software for space applications. The company focuses on building accessible space infrastructure, encompassing ground stations, satellite components, and telemetry systems for rocketry. Key projects include SatNOGS, a globally distributed network of over 200 open-source satellite ground stations, and PICOBUS, the first open-source PocketQube deployer. Libre Space distinguishes itself through its commitment to open-source principles, fostering collaborative development and wider access to space technology. They have demonstrated this capability by successfully building UPSat, recognized as the first open-source satellite in terms of both hardware and software. Current initiatives extend to spectrum monitoring with the PHASMA mission, optical communications development through the Optical MakerSpace, and projects like SIDLOC focused on spacecraft identification and localization, often supported by funding from organizations like the European Space Agency (ESA). Beyond satellite and ground infrastructure, Libre Space also engages in high-power rocketry projects, developing full telemetry and ground segment systems. Their diverse portfolio and collaborative approach position them as a unique contributor to the space industry, lowering barriers to entry and promoting innovation through open access and community involvement.

SatNOGS

Athens, Greece nonprofit

SatNOGS, founded in 2014 and based in Athens, Greece, is an open-source project under the Libre Space Foundation focused on building a global network of satellite ground stations. The company develops and maintains both the ground station network infrastructure and associated software, enabling participatory access to satellite communications. SatNOGS essentially provides the tools and platform for individuals and organizations to connect to and track satellites, fostering a collaborative environment for space exploration and data collection. A key component of SatNOGS is its emphasis on open-source principles. This allows for community contributions to both hardware and software development, driving innovation and accessibility within the satellite tracking field. The project also maintains a crowdsourced, machine-readable database of satellite information, further enhancing its utility as a resource for the amateur and professional space communities. While specific mission details or major commercial customers aren’t publicly detailed, SatNOGS primarily serves the amateur satellite tracking community and those interested in contributing to open-source space technologies. SatNOGS differentiates itself through its commitment to open access and collaborative development. By providing a decentralized, community-driven ground station network, it lowers the barrier to entry for satellite communication and tracking, offering a unique value proposition for enthusiasts, researchers, and organizations seeking cost-effective and flexible ground station solutions.
