The National Small Satellite Program (GNSSP) is the core of Greece's strategy for developing autonomous space capabilities. Within the framework of the program, advanced Earth Observation capabilities are being developed through new national constellations of thermal, optical, and radar (SAR) microsatellites, which will provide high-resolution, low-latency data for critical applications in agriculture, forestry, water, land management, climate resilience, civil protection, and security. These capabilities are supported by national ground infrastructures, such as the upgraded national observatories for secure low-orbit satellite optical communications, as well as the Hellenic Space Tracking Radar (HSTR) for continuous monitoring of objects in low orbit and enhancing European spatial security. The infrastructures and satellite missions form an integrated, nationally controlled mechanism for accessing and utilizing satellite data.

At the same time, the program includes the construction and operation of the HAITF (Assembly, Integration & Testing Facility) at the HAI facilities in Schimatari, as well as the Greek CubeSats In-Orbit Validation program, with 11 experimental CubeSats from universities and industrial entities. The goal is to strengthen the domestic industry, promote research, and create expertise in the design, construction, and operation of satellites with various applications (secure connectivity, Earth observation, spectrum monitoring, etc.).
All these capabilities combine to offer Greece comprehensive operational access to satellite data, through high technological autonomy and a strong domestic industry.
