1 Scope p. 8
The scope of the present document is:
- to identify the main key issues associated with business roles, service and network management and orchestration of a 5G network with integrated satellite component(s) (whether as NG-RAN or non-3GPP access, or for transport), and
- to study the associated solutions.
2 References p. 8
The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
- References are either specific (identified by date of publication, edition number, version number, etc.) or non specific.
- For a specific reference, subsequent revisions do not apply.
- For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

3.1 Terms p. 8
For the purposes of the present document, the terms given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
Geostationary (GEO) satellites:
located precisely in the plane of the Equator at an altitude of 35,786 km, these satellites rotate at the same rate as the Earth's rotation.
Highly-Eccentric Orbiting (HEO) satellites:
satellites with a range of operational altitudes between 7,000 km and more than 45,000 km.
Low-Earth Orbiting (LEO) satellites:
satellites typically deployed in constellations with altitude ranging from 500 km to 2,000 km.
Medium-Earth Orbiting (MEO) satellites:
with altitude ranging from 8,000 to 20,000 km.
Non-Geostationary Orbiting (NGSO) satellites:
These satellites do not stand still with respect to Earth.
