The telecom system (access and service) is seen as the common block between the three systems for aircraft, train and maritime applications. Development, integration and validation of the telecom system on a platform without a real satellite link between the hub and the terminal (only the IDU). The hub-terminal interface is based on an intermediate frequency (like L-band) and may emulate the real satellite link by using a Satellite Link Emulator with static or dynamic profiles.

The resulting developed sub-systems are either prototype or un-optimised commercial equipments. At the end of the validation, the telecom testbed will be ready to be installed and integrated to the aircraft, train and vessel
