raadiosagedussignaalid

Raadiosagedussignaalid, or radio distress signals, are specialized radio signals used to indicate that a vessel, aircraft, or other craft is in distress. These signals are part of the International Distress Signals (IDS) system, which is governed by the International Telecommunication Union (ITU). The primary purpose of these signals is to alert search and rescue services to the location of the distressed vessel or aircraft.

The most commonly used radio distress signal is the Morse code signal "MAYDAY," which is transmitted in international Morse code as three dots, one dash, three dots, and one dash. This signal is followed by the identification of the distressed vessel or aircraft, and any additional information that may be relevant to the rescue operation.

Raadiosagedussignaalid are transmitted on specific frequencies that are reserved for distress and safety communications. These frequencies are known as the Global Maritime Distress and Safety System (GMDSS) frequencies for maritime communications and the Aeronautical Mobile Satellite Service (AMSS) frequencies for aviation communications. The use of these frequencies ensures that distress signals are received by the appropriate search and rescue services, regardless of the location of the distressed vessel or aircraft.

In addition to the Morse code signal "MAYDAY," there are also visual distress signals that can be used to indicate that a vessel or aircraft is in distress. These signals include the use of flares, smoke signals, or other visual indicators that can be seen from a distance. The use of visual distress signals is particularly important in situations where radio communications are not possible or are unreliable.

Raadiosagedussignaalid play a critical role in the search and rescue of vessels and aircraft in distress. By transmitting these signals on the appropriate frequencies, distressed vessels and aircraft can alert search and rescue services to their location and request assistance. The use of these signals is governed by international regulations and is an essential part of the global search and rescue system.
