Software Defined Radios (SDR) have been used to demonstrate the interoperability of military tactical communications based on the High Data Waveform (HDR WF) at Radmor Laboratories in Poland. The OCCAR-led European Secure Software Defined Radio (ESSOR) project aims to break the old paradigm whereby radios from different manufacturers cannot exchange voice or data communications, according to OCCAR.

The demonstration involved radios from Bittium, Leonardo, Radmor and Thales. The successful tests in front of representatives of OCCAR, the European Commission and the European ESSOR nations demonstrated that ESSOR technology enables forces from different member states to communicate with their own radios on the battlefield.

The next interoperability demonstration in 2023 will also involve a radio from Rohde & Schwarz, who joined the a4ESSOR consortium in 2020.

ESSOR is a cooperation programme managed by OCCAR, the Organisation for Joint Armament Cooperation, on behalf of:

  • Finland
  • France
  • Germany
  • Italy
  • Spain
  • Poland

Its objective is to provide Europe with a military SDR capability and to establish a common industrial base to improve the interoperability of European armed forces.
