Thales : A4ESSOR Achieves Acceptance for ESSOR HDR Base Waveform

This step follows two and a half years of development and is crucial for the interoperability of communications between the European Armed Forces.

Oulu, Finland – a4ESSOR SAS (COM)Alliance for ESSOR), a multinational joint venture to develop European Secure Software Defined Radio (ESSOR) technology, has officially adopted its baseline high-speed waveform (HDR) waveform, which has been developed under ESSOR OC1 (European Secure SOftware defined). Radio Operational capability 1) a contract signed with OCCAR (Organization Conjointe de Coopération en matière d’ARmement).

The official acceptance of the basic form of high-speed ESSOR data is after successful acceptance tests in Leonardo’s laboratories in Pisa, Italy last November and official acceptance of quality. It rewards two and a half years of development involving all ESSOR industry partners.

A4ESSOR partners will transfer ESSOR HDR Base Waveform to their respective software radio stations (SDRs) as part of the next phase of the project. The final tests for interoperability between the partners’ radio stations will complete the ESSOR OC1 project, with the release of improved and up-to-date ESSOR target waveforms, ready for deployment in the operational field.

The stage reached not only confirms the maturity of ESSOR technology, but also shows that cooperation between different countries and between different companies is a key element in improving European products and the competitiveness of European industries in the global communications market.

a4ESSOR is a joint venture between Bittium (Finland), Indra (Spain), Leonardo (Italy), Radmor (Poland), Rohde & Schwarz (Germany) and Thales (France). The Joint Undertaking shall be responsible for managing industrial activities under the ESSOR program and coordinating the work of the partners.

The ESSOR program was launched in 2009 under the auspices of European Defense Agency (EDA). The aim of the program is to develop a software-defined radio architecture and the new ESSOR HDR WF coalition to facilitate interoperability between the European armed forces.


The aim of the ESSOR program is to develop pan-European software-defined radio (SDR) technology to improve the ability of the armed forces to cooperate in coalition operations. The program was launched in 2009 under the auspices of European Defense Agency (EDA) and is currently sponsored by the governments of Finland,, France,, Germany,, Italy,, Polandand Spain. The Joint Undertaking Alliance for ESSOR (a4ESSOR SAS) has been selected by the Conjointe de Coopération en matière d’ARmement (OCCAR) to manage an industrial consortium whose members are Bittium from Finland, Indra from Spain, Leonardo from Italy, Radmore from Poland,, Rohde & Schwarz from Germany and Thales from France. In addition to the European High Speed ​​Data Transfer (HDR) waveform, the program has created and validated the definition of a European SDR architecture, which has been transferred and qualified on six different European platforms. The benefits of waveform interoperability are regularly demonstrated through network tests involving different national platforms.
