TACTICAL DATA LINK – FROM LINK 1 TO LINK 22

Tactical data links (TDL) are elements of C4ISR system, which provide a continuous data exchange in (nearly) real time about space, ground, air, surface and subsurface platforms including allied, neutral and foe units data. The main scope of TDL is to provide the operation monitoring capability (for commander) and to send particular commands and data (for subordinates), being one of the basic components of network centric warfare concept implementation. A TDL uses data link standards in order to provide communication via radio waves or cable to transmit, relay and receive tactical encrypted data. This paper aims to outline a comparison between the main TDL standards and their capabilities.
