Centaur® Enhanced High Capacity Data Radio

The Exelis Enhanced High Capacity Data Radio (EnHCDR™) builds on the battle proven networking heritage of HCDR and offers an 8-fold increase in user data throughput using the latest waveform technology.

EnHCDR provides a wide area network ensuring secure seamless connectivity, giving high bandwidth data services to commanders on mobile platforms and forward operating bases.

Advanced ad hoc networking protocols supports minimal management, fast network configuration and reliable communications in harsh environments.

Embedded backbone communications services from main command down to the most forward operating bases avoids the need for vulnerable static communications infrastructure.

The EnHCDR is the most capable radio of its kind creating a communications backbone for messaging, internet and situation awareness applications to support mission-critical on the move operations.

  • self-forming
  • self-healing
  • self-managing
  • highly flexible
  • highly scalable to networks of more than 120 nodes
  • highly spectrally efficient
  • highly energy efficient
  • highly resistant to the Doppler and multi-path common effects of mobility


Planning is straight-forward, large networks can be deployed allowing the radio’s sophisticated algorithms to optimise the network for the resulting topology and mobility. The radio has minimal user input reducing the work load on the operator and minimising training requirements.

EnHCDR includes both wideband and narrowband modes enabling optimum use of available RF spectrum.

EnHCDR is reliable and robust, working in the most demanding conditions.
