The International Code of Signals (INTERCO) is an international system of signals and codes for use by vessels to communicate important messages regarding safety of navigation and related matters. Signals can be sent by flaghoist , signal lamp ("blinker"), flag semaphore , radiotelegraphy, and radiotelephony.
International maritime signal flags are various flags used to communicate with ships. The principal system of flags and associated codes is the International Code of Signals . [ 1 ] Various navies have flag systems with additional flags and codes, and other flags are used in special uses, or have historical significance.
Naval flag signalling undoubtedly developed in antiquity in order to coordinate naval action of multiple vessels. In the Peloponnesian War (431 – 401 BCE) squadrons of Athenian galleys were described by Thucydides as engaging in coordinated maneuvers which would have required some kind of communication; [1] there is no record of how such communication was done but flags would have been the ...
Like Morse code, but unlike Myer's original code, this binary code did not have a fixed length for each character. For instance, i was coded as "2", but d was coded as "222". [ 9 ] Myer's 1866 manual also includes a 3-element fixed length code using four elements, and the 1872 manual has a 3-element fixed length code using three elements.
Virtually all signalling by non-naval vessels is now organized under the International Code of Signals (whether by flaghoist, semaphore, signal lamp, or other means), which specifies a standard set of flags and codes. Naval vessels generally use an extended set of flags and their own codes.
