Understanding CCSDS MO and SOIS EDS in Space Systems
Explore the concepts of CCSDS MO and SOIS EDS in space systems, including sample scenarios, logical and physical MO representations, common interchange formats, and the role of SOIS EDS in system design. Discover terminology, software architecture references, and conclusions on the integration of MO services within the Device Services framework.

Conclusions SOIS has a (draft) reference software architecture into which MO services fit cleanly as a client of the Device Services. Each component of the SOIS reference architecture corresponds to a specified set of OSI layers. In some cases there will be a duplication of functional layers between the internet and subnetwork contexts. Terminology of service , interface and system is not agreed. A diagram similar to the PUS one which shows how a MO- based onboard architecture would be useful, but no one is currently in a position to draw it.
