In the framework of the Iris programme, the development of end-user satellite equipment on ground and on-board the aircraft will be conducted. This will require the development of test beds for interoperability testing, including functionalities not covered by the satellite communication standard.
In this context, one identified activity is the development of an air-ground router (AGR) for the ATM safety communication. The AGR is the point at which the satellite sub-network interfaces with the European Air Traffic Management Network (EATMN). Due to the safety-related nature of ATM communication traffic, specific design and architecture is required for the AGR when compared to commercial off-the-shelf products.
The main objective of the present project is to design, manufacture and test a prototype of an ATN/IPS air-ground router as the interface between EATMN and the ground earth station.
GES switchovers in case of GES failures must be handled in the same sense as handovers and will be addressed within the AGR project as safety communications service interruption over longer periods cannot be tolerated.
Currently there is no commercial IPv6-based air-ground router on the market that would be suitable for future satellite-based links for safety communications foreseen in SESAR. Therefore, the development of the AGR within this task enables first time testing of end-to-end ATC and AOC applications running over an IPv6 network and the satellite-based communication link.
Additional tasks have been conducted with the objective to add the network mobility (NEMO) functionality and verify NEMO support with the integrated air-ground router and mobility testing environment.
