HELLENIC SPACE DAWN
The Hellenic Space Dawn (HSD) project aims to design, develop, launch, and operate Greece’s first twin CubeSat constellation—Selene and Helios—for Earth Observation (EO), marking a decisive step toward national autonomy in satellite technologies and applications. Through this mission, Greece strengthens its capacity to produce, process, and utilize satellite data to support cartography, agriculture, forestry, and land-use monitoring, while demonstrating advanced on-board data processing capabilities such as vessel detection and image compression. By bringing together Greek SMEs, universities, and research institutions under ESA coordination, the project fosters a sustainable domestic space ecosystem and aims to position the HSD constellation as a Copernicus Contributing Mission, providing freely accessible EO imagery in support of Europe’s digital and green transitions.
Geosystems Hellas (GSH) leads the development and operation of the Payload Data Ground Segment (PDGS) for the Hellenic Space Dawn mission, enabling satellite tasking, data processing, and generation of Earth Observation products. By defining the technical specifications of the Selene and Helios CubeSats and transforming raw satellite data into actionable geospatial information, GSH strengthens Greece’s capacity for independent satellite operations and EO data exploitation.
