European Secure Software-defined Radio (ESSOR) is a planned European Union (EU) Permanent Structured Cooperation project for the development of common technologies for European military software-defined radio systems, to guarantee the interoperability and security of voice and data communications between EU forces in joint operations, on a variety of platforms.[1][2][3]
History
The project was based on United States' Software Communications Architecture and Joint Tactical Radio System,[4] to which Thales was a major contributor. Germany initially did not participate in ESSOR, developing instead its own SDR system, Streitkräftegemeinsame, verbundfähige Funkgerät-Ausstattung.[5]
