National Tactical Data Link Network - NTDL

 

Operational Concept

ISI’s National Tactical Data Link system provides tactical surveillance and command and control information exchange amongst the various military assets where it is installed. The system is able to:

  • Integrate the concerned military Assetsand Ground Stations into a common tactical network, where information can be exchanged in a standardized, efficient and secure fashion
  • Create and distribute the Common Tactical Picture (CTP) amongst the network participants and disseminate it to higher echelons of the hierarchy (from Tactical, to Operational to Strategic), thus increasing overall Domain Awareness
  • Provide for Command and Control information flow and capabilities and allow interoperability amongst the network participants
  • Enable the efficient and seamless integration of additional units/platforms (Naval, Land and Air) into the the NTDL network in the future. This is achieved through the built-in open architecture of the proposed systems

 

 

System Components

ISI’s National Tactical Data Link Network system comprises of the following components:

  • National Data Link protocol – ISI’s NTDL with a complete definition of message sets and data elements
  • Data Link Processor - Universal Link System (ULS) acting as:
  • Data Link Forwarder
  • Common Tactical Picture (CTP) generator
  • Tactical Information Manager (Reporting Responsibility handling, IFF/ID Conflict detection and resolution, track handling etc.)
  • National Data Link Integrator to other C2 systems (using Application Programming Interface – API)
  • Radio Distribution Sub-System consisting of an Integrated Crypto/Modem/Radio unit – a wireless, high-speed, secure, IP network which forms the communications infrastructure for C4I applications

ISI’s NTDL Protocol is a best-of-breed TDL protocol based on legacy and modern standard TDLs, featuring a complete set of features and supported operations, providing at the same time interoperability with other Standard Data Links via Gateways (ULS).

It is comprised of a fully defined message set and data elements, with clearly defined forwarding/translation rules with other Standard Data Links, with over 40 years of operational history, supporting the following types of operations:

  • Air Surveillance
  • Surface/Maritime Surveillance
  • Subsurface Surveillance
  • Electronic Warfare
  • Intelligence
  • Command and Control
  • Weapons Management and Coordination
  • Information Management

Additionally, its open modular architecture and interfacing protocols allows for possible future requirements:

  • Expansion at the data element and message level to provide for coverage of other operational functions, such as real time images and video
  • Incorporation of possible dissimilar data links used by other assets (existing or future)

Benefits

  • Field proven and operational solutions in more than 10 countries
  • Exportable ITAR free technology with the possibility of transferring NTDL’s technology to the corresponding local organization
  • Fully customizable and expandable to take into consideration the end-user’s operational requirements
  • Minimum configuration and initialization effort allowing fast reaction time
  • Full IP based solution, providing easy integration with existing and future systems
  • Wideband Software Defined Radio (SDR) RF Distribution Sub-System
  • Fully automatic RF Network formation, no need for user intervention
  • Plug-and-Play once configured
  • Secure and anti-jamming RF network (Two-Layer Encryption, Network Association /Authentication mechanisms, Adaptive Frequency Hopping, Automatic Transmit Power Control, Directional Emissions, Adaptive Modulations)
  • Compact and embedded Modem/Router/Multi-Servers/Crypto/Radio unit (cost saving factor, due to the fact that there is no need for additional external devices)
  • Simultaneous support for NTDL, multiple Voice, Data and Video services through the same RF channel (force multiplier factor)
  • Generate and disseminate the Common integrated situational Operational Picture (COP), thus improving Situational Awareness (SA) throughout all Command Levels
  • Provide a secure backbone for inter and intra service exchange of tactical information within the Armed Forces environment
  • Integrate all units/platforms into a common tactical network with appropriate information forwarding and/or relay by multi-link capable gateways
  • Integrate the tactical data link capabilities of existing or in-development units and platforms
  • Enable Network-centric operations
