  Different arguments were being presented in the last decade about CubeSats
and their applications. Some of them address wireless communication (5G and 6G
technologies) trying to achieve better characteristics as coverage and
connectivity. Some arrived with terms as IoST (Internet of Space Things),
Internet of Satellites (IoSat), DSS (Distributed Space Systems), and FSS
(Federated Satellite Systems). All of them aim to use Small/NanoSatellites as
constellations/swarms is to provide specific services, share unused resources,
and evolve the concept of satellites-as-a-service (SaS). This paper aims to
emophasize performance attributes of such cyber-physical systems, model their
inherent operational constraints and at the very end, evaluate the quality of
service in terms of figures of merit for the entering/leaving of new
heterogeneous constituent systems, a.k.a satellites, to the constellation. This
"whitepaper"-styled work focuses on presenting the definitions of this
heterogeneous constellation problem, aims at its main capabilities and
constraints, and proposes modeling approaches for this system representation
and evaluation.
