Link 11

from Wikipedia, the free encyclopedia

Link 11 (v. Engl. Link for connection ) refers to a military data exchange standard for data links of NATO , specifically in the Navy but also in parts in the Air Force is used (link 11B).

Link 11 was developed in 1955 by the US Navy and the US company Rockwell Collins and is used for the automated exchange of situation picture information between the command systems of ships and aircraft. Link 11 with its data definitions and its set of rules is laid down in the Standardization Agreement STANAG 5511.

Link 11 uses UHF or HF radio links to transmit the digital information, with a Net Control Station querying all units in the network one after the other (full roll call). Because of its susceptibility to failure and low data rate, it is now technically out of date. Link 16 development began in 1975 and the US Navy shipped the first Link 16 applications in the mid-1990s. Nevertheless, Link 11 is still used by many navies as the primary information medium for exchanging situational information and giving orders in real time.

Since 1992 they have been developing Link 22 (also known as NATO Improved Link Eleven; NILE), which will replace Link 11 in the future.

Link 11B is based on a direct connection , whereby two remote stations exchange data.
