An SOS is a Distress Signal sea, used between 1908 and 1999. Currently the system is used Global Maritime Distress Safety System.
Many people believe that SOS is an acronym for "Save Our Ship" (save our ship), but that does not correspond to reality. The SOS signal back to the early days of radio, when there was no voice and the messages were sent using Morse code.
The S and the characters are represented in Morse code by 3 rapid beeps (3 points) and time-consuming three beeps (three dashes). The signal was then heard as "beep beep beep beep beep beeeeep beeeeep beeeeep beep." , Which produced a very distinctive sound and this is why the use of these two letters. It is this new idea of assigning meaning to an SOS.
