Interoperability vs Integration – What’s the Difference?
How can systems engineering effectively support technological development at pace? The validation of integration, defined as the process of combining two or more things in a successful way and interoperability, defined as the degree to which two or more programmes can be used together, is key for all future development activities, from conception to application and across all domains.

Landing at 3 Counties Defence & Security Expo Showcase
This flagship event takes place at the Three Counties Showground in Malvern on 3rd & 4th November 2021. We will be participating in the MAKE UK Defence pavilion on day two of the event – 4th November. Read more about our attendance on pages 7-10.
Requirements Management & Model-Based Testing in Defence
The application of requirements-based testing, underpinned by a model-based approach during requirements definition, helps to identify issues early in the development life cycle. This article from the archives looks at how MBSE serves to minimise costs and risks in the development and maintenance of the system, as well as providing a direct correlation between clarified requirements and test cases for validation and verification purposes.
Military Avionics Access to Hyper Connected Air Traffic Management
The modernisation of civil aviation Communications, Navigation and Surveillance (CNS) infrastructure is underway. Future aviation concepts will rely upon highly automated and hyper connected Air Traffic Management (ATM) systems. This latest guest article is an abridged abstract of a EUROCONTROL paper written by Jorge Pereira, Head of the CNS Coordination Unit within the Civil Military ATM Coordination Division at EUROCONTROL.
The Value of a Simulated
Training Environment
Simulation technology presents huge opportunity for the TDL industry; as simulated TDL experiences and technology becomes more sophisticated, so too does the ability to imitate real-world scenarios. This article looks at the benefits and value.
Meet the Trainer: James Norful
Consultant James “JJ” Norful, 40, who lives in Heinsberg Germany, is a retired United States Air Force (USAF) Senior Surveillance Technician. Having spent 21 years flying on both the US and NATO AWACS, he brings a wealth of experience in the operations of TDLs.
Agile Systems Engineering
Many industries have now reached the threshold of complexity past which traditional methods of project management are no longer up to the task, but aerospace and defence was the first, and systems engineering was the result. This article explores how Agile and Systems Engineering can be combined to better manage complex TDL programmes.
Best Supporting Actor
Evolving the Airborne Early Warning (AEW) Mission. An article provided by Athanasios Chouliaras via Armada International that examines how the electronic support mission performed by AEW aircraft is often overlooked and how this mission could be evolved.
Gordon Welchman – The Father of TDLs
World War Two (WW2) code-breaking ace Gordon Welchman can justifiably be described as one of the founding fathers of modern-day Tactical Data Links. Although subsequently overshadowed by the fame of Bletchley Park colleague, Alan Turing, Cambridge University maths genius Welchman was Turing’s equal in the cracking of the Nazi Engima code. Welchman was later responsible for helping to develop the Joint Tactical Information Distribution System (JTIDS). This article explores Welchmans legacy.
TDL Interoperability Testing
What happens if you don’t test interoperability? Should we ‘dangle a carrot’ or ‘beat you with a stick’? This article looks at some of the potential consequences of neglecting to rigorously test TDL Interoperability by shining a light on some specific industry examples.
Demystifying TDLs - The Development of TDLs
In the last two editions of TDL Technology, our series on the demystification of TDLs looked at why we need TDLs, and the TDL Standards which govern the technical specifications of these systems. This article will examine the evolution of TDLs by making a chronologically ordered comparison of four major TDL systems – Link 11A, MIDS Link 16, Variable Message Format (VMF) and Link 22.

Link 16 Evolution: Making a Military Communications Protocol Even Better
We thank our guest contributor, Viasat for the article contribution which explains how they are helping the U.S. military adjust to new mission needs, enhance situational awareness, adapt to new technologies and improve warfighter safety.
iSMART Explained: A Look at the iSMART Document Suite
Defining the required functionality for Tactical Data Link systems is a complex process: which elements of the standards, do we need, is there anything we can change, and how do we document the decisions that were made?
