What does SOS mean in INTERNATIONAL

The SOS signal stands for “Save Our Souls,” or “Save Our Ship.” It is an internationally recognized distress call used to indicate that a person or group is in need of immediate assistance.

The original SOS signal was developed by the German Government in 1905. It soon became the international Morse radio-code for indicating distress.

The standard SOS distress call is transmitted as three dots, three dashes and three dots - ---... - using Morse code over voice radiotelephone transmissions.

Besides radio transmission, some other ways you can send out an S.O.S include flares, flashing lights from a flashlight or handheld mirror, writing messages on sheets of paper visible from a distance, smoke signals, whistles and fire guns (blank cartridges fired at 4 minute intervals).

Yes, most smartphones have built-in apps or tools that allow you to quickly send GPS coordinates and alert emergency responders to your exact location via text message or phone calls in times of need ([for example name app]).

Yes, each country has its own specific protocol when it comes to responding to distress transmissions due to differences in search and rescue operations and procedures across countries and regions. For instance some countries use additional signals like 'VVV' along with 'SOS'.

Yes, phonetic alphabet is also used when transmitting an SOS signal as it often reduces confusion caused by static noise on the radio frequency channel where visual contact cannot be established easily (for instance "MAYDAY").

No, there isn't one specific frequency designated for distress calls; however broadcasts are most likely heard if sent out on 2182 kHz (which is known as the ‘international calling and distress frequency’).

Any type vessel can broadcast using this international Morse radio-code signal as long as they have access to suitable communications equipment.
