  This paper provides an overview of the diverse range of applications and use
cases for Single-Channel Full-Duplex (SCFD) techniques within the field of
satellite communication. SCFD, allowing simultaneous transmission and reception
on a single frequency channel, presents a transformative approach to enhancing
satellite communication systems. We select eight potential use cases with the
objective of highlighting the substantial potential of SCFD techniques in
revolutionizing SatCom across a multitude of critical domains. In addition,
preliminary results from the qualitative assessment are shown. This work is
carried out within the European Space Agency (ESA) ongoing activity FDSAT:
Single Channel Full Duplex Techniques for Satellite Communications.
