IRIDE is an Italian Earth observation satellite programme developed under the National Recovery and Resilience Plan (PNRR) and the National Complementary Plan (NCP). Coordinated by the European Space Agency (ESA) in collaboration with the Italian Space Agency (ASI), IRIDE aims to establish a comprehensive satellite constellation for environmental monitoring, disaster management, civil protection, security, and public administration support. The programme, involving over 73 Italian companies, is set to be fully operational by June 2026 and is designed as a "constellation of constellations" with advanced sensor technologies.
