Tactical Data Links - Link 14
Key words and phrases: tactical data links, link 14, maritime units, ADatP 14, STANAG 5514
Link 14 is a broadcast HF teletype link for maritime units designed to transfer surveillance information from ships with a tactical data processing capability to non-tactical data processing ships. The design of the teletype transmission allows reception over very long ranges.
Link 14 provides the capability to broadcast picture compilation and status information for use in units unable to receive Link 11 transmissions either direct or via an interface, e.g. non-Tactical Data System (TDS) units. The Link can be either HF, VHF or UHF dependent on unit-communication fits.
More than one Link 14 net, with or without separate transmitting units, may be set up if desired, e.g. to split air and surface/sub-surface data. However, some units will be limited by communications fits in their capability to receive two nets. Few units will have the capability to transmit on two separate Link 14 channels at the same time. Selection of the Link 14 transmitting unit will depend on force disposition stationing of non-TDS units, Link 14 frequency, etc.
Each nation within NATO has its own Link 14 transmission formats which are promulgated in ADatP 14. Message protocol is defined in STANAG 5514.
