The student must realize un analysis of message calogues employed in different networks searching for interoperability among them. The subset of messages shall be employed to develop a simulation that generates messages of each network and interchanges the interoperable message.

The main objective of this Project is to perform a compatibility study between three different communication network messages: TADIL-J's, CCSDS and AP04. This Project firstly consists on the research of documentation concerning each communication network message. Subsequently the compiled documentation is cross-documented between communication networks for a further interoperability study. The aim is to specify similarities and dissimilarities between the messages. Thanks to the stated processes it is then possible to implement the attestation to a java-based program, which is the responsible of showing and translating between messages. The results obtained are the fruits of the interoperability and software simulation design processes. The last part of the memory describes verification process, which makes sure that the results obtained are suitable according to the standards of the Project. The contents of this Project are purely explanative. It describes the established guidelines, the marked objectives, and the difficulties that appeared throughout the entire Project, the techniques to abroad the problems and the results obtained. The practical results of the work are contained in the annex of this document.
