6G SmartSat provides a testbed and proof of concept demonstrator with the following goals:

• To provide a suitable environment for rapid testing of routing, specifically semantic routing, solutions accounting for the physical characteristics of the multi-layer non-terrestrial network system;
• To provide a suitable framework for running an extensive number of simulations aiming to discover side-effects and limit cases in the proposed routing system;
• To provide an emulation environment in which hardware components can be embedded and tested, emulating realistic links to be able to determine the impact of different technologies on a single node.
