How does Tactical Messenger work?

Tactical Messenger sits alongside your messaging system to enable reliable communications in a low-bandwidth environment typically used by maritime or deployed land forces.

By reducing the data size of communications to optimise the use of low-bandwidth channels, and intelligently prioritising the most urgent and important communications, you can be confident that important messages can be received, even in the most challenging environments.


  • Efficient for low-bandwidth environments

    Make the best use of use of constrained bandwidths as low as 300 bits per second by maximising the efficiency of the communication channels you are using.

  • Faster communication

    Tactical Messenger gets the most out of high latency satellite links by using ‘non-blocking’ protocols.

  • Reliable communication

    Robust systems to cope with high error rates typical in communication channels, making Tactical Messenger more reliable.

  • Make use of a variety of messaging mediums

    Tactical Messenger enables you to use multicast messaging to make use of a variety of messaging mediums such as radio, satellite etc. compensating for low bandwidth.

  • Use with EMCON environments

    Send EMCON (Emission Control) messages for receipt by deployed units who do not wish to broadcast signals, in order to help hide their location.

  • Intelligently ensure your most important messages get through

    Prioritisation of messages to ensure highest priority messages are transmitted first in a low-bandwidth communications channel.


  • Message priority and precedence management
  • Message interruption for higher priority message transmission
  • Intelligent management of messaging queues to ensure important messages are transmitted
  • Supports NATO STANAG 4406 Edition 2 Annex E, ACP123 and ACP142 (P_MUL) standards
  • Interoperates with a corporate messaging system such as Microsoft Exchange Server 2003, 2007 or 2010
  • Reliable multicast messaging to reduce the overall traffic on the network
  • General purpose data compression to reduce data transfer volume
  • Supports mobile operations using radio based networks including STANAG 5066 systems
