Tactical data link character
TDLs are characterized by their standard message and transmission formats. This is usually written as <Message Format>/<Transmission Format>.
TDL standards in NATO
In NATO, tactical data link standards are being developed by the ''Data Link Working Group (DLWG)'' of the ''Information Systems Sub-Committee (ISSC)'' in line with the appropriate
STANAG
In NATO, a standardization agreement (STANAG, redundantly: STANAG agreement) defines processes, procedures, terms, and conditions for common military or technical procedures or equipment between the member countries of the alliance. Each NATO st ...
