Military, Aerospace & Government

Trilogy offer a range of modular intercom solutions that can be tailored to the specific needs of any industry or government agency. Incorporating best practice security standards with cost-effective IP telecoms, Trilogy systems can be used to complement, replace or consolidate your existing intercom platforms. With multi-level security options Trilogy systems can bridge multiple networks or security domains while ensuring complete security of the most sensitive domains.  All these capabilities are provided in a COTS product helping to reduce the cost of deployment and the overall total cost of ownership.


Adhering to the highest security standards, Trilogy solutions provide robust communications channels without ever compromising internal or external defences. Trilogy has worked with air forces, armies and navies across the world to deliver reliable, cutting edge communications that keep key personnel connected at all times.

Powerful customisation and management tools allow for rapid system deployment in the most demanding environments, including in theatre. And with full support for IPoS (IP over Satellite), secure communications can be deployed anywhere in the world within minutes.

Mercury’s expansion options ensure connectivity can be seamless across a wide range of technologies including:-

  • Radio interoperability (both analogue and RoIP)
  • Tetra option
  • Telephony (FXO, FXS and SIP)
  • IP integration
  • E&M

Specially designed for the secure communications requirements of military personnel and contractors, the Mercury ES product range provides a rock-solid, security-first platform for internal and external communications.

On the ground or in the air, Trilogy has a wealth of experience designing intercom solutions that meet the unique challenges of the aviation industry.

Using IP-based technologies, Trilogy intercom units provide cost-effective communications for ground staff, ensuring the free flow of timely information across sites. The intercom system can be further extended using VoIP bridging and connectivity across multiple buildings, unifying communications at minimal cost and providing fail-over provisions to reduce the risk of comms network outages.

Whether deploying an inter-site intercom system, or building a global framework for unified emergency communications, Trilogy has a range of scalable IP-based solutions to fit. The combination of interoperability and secure bridging between networks makes the system particularly suitable where an operation center or Joint Operation Center (JOC) is being created.

Trilogy intercom solutions also allow for a two-tier system, creating secure networks that segregate communications, maintaining privacy and preventing data leakage or unauthorised access. A fully flexible, interoperable structure allows for the construction of a fully bespoke intercoms system to suit any application.

Trilogy's flexible communications systems provide a comprehensive solution to the communications needs of naval vessels. With small physical size and a COTS cost point Trilogy's systems are ideally suited to the needs of Inshore and Offshore patrol vessels. Not only does it meet all the needs for communications within the vessel, but radio and telephony integration means communications can be established from vessel to vessel, to shore or supporting aircreaft.

Using either IP or Analog audio the same system also supports the requirements for Broadcast and Alarm. A wide range of devices with IP 65-67 accreditation means the appropriate stations can be selected for on deck as well as internal useage.
