Our reserach group will address the design and evaluation of physical layer and multiple access techniques for the forward and return links of the IRIS system.

The future European Air Traffic Management (ATM) is currently being defined by the Single
European Sky ATM Research (SESAR) programme.

In the SESAR Definition phase, the need to evolve from voice based communications toward data
links between the aircraft flight management system and the ground Air Traffic Control (ATC) and
Airline Operations Centre (AOC) systems is clearly stated. It has driven the requirement for a dual
link solution to guarantee the necessary availability and capacity, especially over dense traffic
areas. This dual link is expected to include a terrestrial and a satellite-based component.
Accordingly, Research and Development for new satellite based Air/Ground datalink has been
recommended in the ATM Master Plan, resulting from the SESAR Definition Phase (2006-2008)
and endorsed by the EU Transport Council. In particular, the need for new performance standards,
which calls for a new ATM-dedicated satellite communication standard and supporting satellite
capacity, is widely shared among stakeholders. The ATM Master Plan however only indicates the
set of solutions to be further evaluated and possibly validated. The choice concerning which
technologies to deploy is to be made later by the EC on the basis of the aviation community

In parallel with this Ph B development, the Agency is sponsoring studies with potential operators
and on the evolution of commercial satellite communication standards, to provide the future users
with a range of credible choices and a competitive environment.

Because the aviation world operates on a global basis, any new ATM solution must be supported
and coordinated on a worldwide basis; this requires ICAO standardisation and coordination with
the international stakeholders leading to support for the new standard. Through ICAO
standardisation, Iris will promote a European developed standard and the associated technology on
the worldwide market.

In parallel, the overall satellite communication system infrastructure needs to be designed. This
will only be regional (e.g. covering Europe) at this stage, but it is fundamental to guarantee aircraft
avionics and ground segment interoperability with other systems so that aircraft can fly seamlessly
and transparently from one regional system to the next.

The European regional system must be designed and specified according to the SESAR
requirements and ready for deployment during the SESAR deployment phase (2014-2020) with the
aim to start operations in 2020.
