An Introduction to Tactical Data Links

This Foundation level guide introduces some of the basic concepts of Digital Data Links (DDLs) and discusses the value of these techniques to military applications and examines some of the DDLs that have been used by the North Atlantic Treaty Organisation (NATO) to support tactical operations during the last few decades.


Although some DDLs have been developed specifically for strategic and other

uses, this book focuses on those systems which can be defined as Tactical

Data Links (TDLs).

A must-read for those new to the world of TDLs or those wanting the essential basics all in one place.
