Title:
T603-37ET
Future Multipurpose TT&C Systems & Techniques
The objective of this activity is to investigate, analyse and propose new TT&C Communication Systems looking to the overall
end-to-end perspective for a broad range of possible missions (e.g. from Near Earth to Deep Space). The target is to devise a
flexible tool-kit of solutions for both the on-board and ground system which can be embedded in highly reconfigurable
hardware platform to adapt to the different mission needs. This approach will avoid the use of expensive ad-hoc solutions to
cope with the different missions and will be leveraging on the advances in signal processing techniques and technologies.
Stemming from the requirements envisaged for future TT&C applications (and for the different application fields: Science,
Earth Observation, Navigation and Telecommunication), this activity shall investigate a flexible yet robust solution for TT&C
tackling aspects such as: spectrum congestion (interference, spectral efficiency, frequency reuse...), on-board power
efficiency (nonlinearity countermeasures), link security, mission adaptability etc....
Deliverables:
Analysis of curent/future application scenarios/req. Broad review of possible comm. link + ranging approaches. Identification
of ref. scenarios, overall end-to-end perform. analysis + trade-off. Proposed solution benchmarking current approach.

Title:
Design and Synthesis of a New Class of Receiver Filters
With the increasing complexity of satellite payloads there is increased demand of miniaturized high performance receiver
filters. This includes waveguide and planar filters. Current synthesis techniques assume close to lossless (high Q) networks
which forces the filter to be reflective. If this restriction is removed a new degree of freedom is achieved and very high
performance filter transfer functions can be acomplised utilising very low Q resonators. Initial estimations show that the for
same size significant improved flatness and selectivity can be achieved over state of the art predistorted topologies.

Circuit design tool and breadboard demonstrators
