Iris - Satcom for Aviation

The Iris Programme aims to make aviation safer, greener and more efficient by developing a new satellite-based air–ground communication system for Air Traffic Management (ATM), in partnership with Inmarsat. By 2028, Iris will enable full 4D trajectory management over airspaces across the globe and the data link will be the primary means of communications between controllers and cockpit crews.

  • Iris Convergence

    Two approaches were considered in the past for the long term evolution of the safety critical satcom for aviation: Purpose built system with custom air interface (ANTARES) and the incremental evolution of Inmarsat’s system and services (Iris Precursor, Iris Service Evolution). This study helps to converge the two approaches and find synergies.

  • Iris Service Evolution

    Iris is Europe’s latest development in satellite-based aviation safety services. The Iris Service Evolution is looking into the technology, operational and strategy roadmap to meet the long term requirements for air traffic control services aligned with the SESAR Future Communication Infrastructure objectives. It follows the activities conducted...
