Low Cost - Operationally Proven - Submarine Satellite Communications
Our partners with support from other agencies have designed, manufactured & qualified a range of low cost Submarine Mast Top Assemblies (MAT) to support the Commercial of the shelf (COTS) Marine IMMARSAT and Broad band 500 and 250 SATCOM systems
The submarine Mast Top Assemblies (MTA) are Operational
Broadband 500 and 250 SATCOM systems.
The illustration shows the core Fleet 55 MTA (EMS) which has been designed for universal fitting to any submarine mast.
This hermetically sealed MTA is fully compliant with UK MoD DEF STAN requirements.
Requires no additional cooling or other electrical services other than that currently provided by the INMARSAT COTS terminals
Submarines Antenna Structure
Our Partner Design bespoke antenna’s to meet high performance requirements for defence and commercial markets.
-
Antennas are wide band and high gain
-
Low form factor, easily concealed
-
Light, easy connectivity
We work with systems suppliers to provide complete communications /Electronic counter measure (ECM) requirements of customers.
Designs are developed utilising specialist software and these predictions then confirmed / tuned on the development model following testing.
Other Naval Applications
Indicator buoy modules
Submarine indicator buoys must be manufactured from pressure and shock resistant materials to meet extreme operational performance requirements.
Indicator buoy modules are stand-alone, self-supporting units fitted to submarines and designed to be launched in the event of a sub-sea accident. On launch, because of unique composite construction, the buoy ascend under natural positive buoyancy, remaining tethered to the submarine, to emit a distress signal.
