Dimensioning requirements for the ANTARES ATM satellite data-link

▪ Iris is a dedicated ESA programme to develop a new satellite based air-ground communication system for air traffic management on the basis of the SESAR requirements. ▪ The analysis of the system dimensioning requirements is provides input to the system design. ▪ Air traffic: - In the investigated beam configurations (3 beams, 12 beams) the Iris satellite system has to support between 600 and 4500 A/C per beam. - In total the system need not support more than 6000 A/C. - Handover between beams are performed at rates < 1 HO/s.
