Navigational beacons overview

Visual aids to navigation : using lamps or fire to indicate location at night

  • Basic Requirements
    • Aids should be seen within the required range
    • Aids should be clearly separated from other lights with certain features to allow for seafarers or observers to identify them without difficulty
    • Blinking intervals should remain constant and accurate, and easy to identify by seafarers
    • Lanterns and light sources should have high efficiency and credibility as far as possible
    • Aids should comply with proper safety standards in order to meet usages requirements and purposes of aids with regard to geographical navigatio

Shape Aids to Navigation : indicating the location with shapes or colors during daytime

  • Basic Requirements
    • This system employs a simple arrangement of shapes and colors to mark a location during daytime
  • Types of Shape Aids to Navigation

Sound Aids to Navigation : indicating a location by generating sounds when visibility is restricted by fog, snow, rain, etc.

  • Basic Requirements
    • Sound aids to navigation inform their location to vessels with sounds generated by sound waves.
      Machines that generate sound waves for this purpose are fog signals
    • Fog signals are built in areas or harbors of often restricted visibility by fog, snow, sunset, heavy rain or haze. Under these conditions, they are operated day and night. They have a relatively short range, as they are operated by sound. Moreover, the range and direction of sound vary according to weather or sea conditions
  • Types of Shape Aids to Navigation

Radio Navigation : Using it as indicators for navigation by taking advantage of the various characteristics of radio waves

  • Basic Requirements
    • Every indicator with the features of radio waves such as straight, constant velocity or reflexibility for vessels or airplanes is called radio navigation or radio-beacon. As it makes use of radio waves, it has the advantages of availability under any conditions and range across a broad area.
  • Types of Shape Aids to Navigation

Special Purpose Aids to Navigation : Sending various navigation information including vessel traffic or tidal current directions with radio waves or shapes to navigational vessels during day or night in narrow straits or waterways.

    • VTS : Designed to guide vessels for safe navigation by installing radar and CCTVs in waters like port entrances or channels, or narrow channels
    • Tidal Current Signal Station : A large screen signal system indicating strength and direction of tidal current to navigational vessels sailing in strong waters like harbor entrances or channels, or narrow channels
    • Weather signal box : Designed to give necessary information like special weather reports to navigational vessels
    • Radar Beacon : A radar response unit to show the location of a transmitting station with Morse-code on a vessel's radar screen
