Integrated communications control system (ICCS)

ICCS provides secure and reliable communications for any type of warship, from patrol boats and submarines to frigates and aircraft carriers. This state-of-the-art system is designed to enable efficient control and management of the ship’s overall communications, featuring:

  • Internal and external communications
  • Equipment remote control with real-time status monitoring
  • Embedded training facilities
  • Gateway to the Combat Management System (CMS)

A flexible design enables a variety of system implementations, as far as the architectural aspects are concerned. Depending on the ship size and operational role, either centralised or fully distributed versions can be selected.

Currently two generations are available: ICCS6, a brand new, IP-based version and the ICCS5, the TDM version.

ICCS6 is essentially composed of:

  • Network Centric Switches (NCS), providing the necessary digital and analogue interfaces for non-IP communications devices
  • Multi-Functional Units (MFU), used to reduce ship’s cabling. These units aggregate several communications equipment into a single Ethernet interface
  • EIDCOM 400 User Terminals, with multi-level security, featuring a touch screen, graphic display and through which external and internal voice communications are performed (see photo)
  • Management Terminals (MT), enabling a single operator to fully control and supervise the system, through an user-friendly human-machine interface

As far as ICCS5 is concerned, its main components are:

  • Network Access Units (NAU), providing digital and analogue interfaces as required by the communications system components, being responsible for switching and signal distribution functions
  • Voice terminals, through which external and internal voice communications are performed; two models – EIDCOM320 and EIDCOM120 – are available (see photos)
  • Management Terminals (MT), common to both ICCS versions

In brief, the ICCS system concept is fully proven, with an internationally recognised and outstanding performance. ICCS is in service onboard more than 100 warships of navies of several countries, such as Portugal, Spain, UK, The Netherlands, Brazil, Indonesia and Australia.

Marine wireless headsets (TWH-101N)

The wireless headset is designed to overcome the limitations of the traditional, cumbersome wired headsets. It is composed of a compact radio unit and headset, the same used with the voice and user terminals. To enable wireless communications, a proper gateway and antenna must be installed in either the EIDCOM320 or EIDCOM400. The main features are:

  • Simultaneous operation of external and internal circuits
  • Encrypted communications with the voice/user terminal
  • Wireless operation enabled/disabled by the user on the terminal
  • Up to 64 users (reception)
  • Spread spectrum technology on 2.4Ghz
  • RF output power: -1dBm up to +24dBm
  • Autonomy: up to 8 hours (16 hours with additional battery pack)

Battery chargers are also available to charge the radio units.

Most4 Ships – automatic message handling system

MOST4 Ships is an automatic message handling system, featuring a comprehensive set of facilities aimed at reducing the overheads of traditional, on-board message management tasks. Providing a substantial degree of automation, the system reduces the operator’s workload, thus minimising the likelihood of occurrence of operational and administrative mistakes.

The reduction of the ship’s complement is also a significant benefit to skilled communication operators. MOST4 Ships supports the simultaneous operation of all circuits (ship-shore, inter-ship, local and area broadcasts) in accordance with ACP127 message formats and procedures.

STANAG 4406 compliant solutions can also be integrated into MOST4 Ships, fulfilling ship message requirements in a transition period from ACP 127 to Tactical MMHS.

RRCS – radio remote control system for communications equipment

RRCS can be tailored and configured to provide centralised remote control of any type of communications equipment, enabling effective control and monitoring of its working parameters.The system is composed of:

  • Multi-Functional Units (MFU) providing the necessary remote control interfaces (serial ports or Ethernet ports) to communications equipment; they are suitable for rack installation, with just one unit height
  • Management Terminal (MT) enabling a single operator to fully control and supervise the system.

Systems integration

EID supplies state-of-the-art, high-performance fully integrated communications systems, with ICCS as the core sub-system that glues together all on-board communications equipment, equipment/sub-systems selection and supply. EID also carries out all design and engineering activities required to supply a fully integrated, operational system.
