TYPES OF NAVIGATION EQUIPMENT USED ON MODERN
SHIPS, AN OVERVIEW!!!
2

• Nowadays, sailors are well-trained to handle all
  modern navigation equipment to make sailing
  smoother and safer at sea.
• The vessel today is equipped with various
  advanced navigation systems that provide accurate
  voyage data. Thanks to modern facilities and
  automation.
• Lets look into both old and new navigation
  equipment used by merchant ships.

• Gyro Compass Marine
• It uses a gyrocompass to determine its direction.
  Unlike a magnetic compass, it is not affected by
  an outside magnetic field. Additionally, it
  supplies the accurate axis of rotation for the
  Earth, resulting in a reliable directional
  source.
• Radar
• To avoid collisions, marine vessels rely on
  S-band and X-band radar in Dubai to detect
  targets and display information on the screen
  such as distances from the ground or any floating
  objects (islands, icebergs, rocks, etc).
• Magnetic Compass
• To determine the planned route of a voyage, a
  magnetic compass is used. Along with Earths
  magnetic field, it operates simultaneously.
  Navigators use it as their primary direction
  indicator.

• Echo Sounder
• There are many modern shipborne navigation
  instruments onboard and the echo sounder is one
  instrument that has been in use for nearly 100
  years. With the principle of sound wave
  transmission, it measures the depth of water
  below the bottom of a ship.
• Electronic Chart Display Information System
  (ECDIS)
• The Electronic Chart Display Information System
  (ECDIS) is a navigation chart system used on
  ships. A ships location can easily be determined
  using this method.
• Automatic Identification System (AIS)
• AIS helps to accurately identify the position and
  other navigation statistics of ships. AIS sends
  and receives messages between ships using VHF
  radio channels.

6

• Voyage Data Recorder (VDR)
• There is a voice recording system in the VDR that
  keeps a record of the last 12 hours of
  conversations. Any future investigation will be
  based on this information. Rate of turn indicator
• This navigation tool displays the degrees of
  turn, i.e, how fast the vessel is turning at a
  constant speed. The turn rate of a ship is
  calculated in degrees per minute. Also, it helps
  the navigator to steer the course safely.
• GPS Receiver
• GPS receiver is a global positioning system (GPS)
  receiver is a display system used to display the
  location of a ship using a global positioning
  satellite in earth orbit.

• ARPA
• It is a feature on the radar that constantly
  monitors the condition of the ship. It
  automatically determines the number of targets
  for you, such as ships, boats, stationary or
  floating objects etc. and denotes their speed and
  course accordingly.
• Autopilot
• An autopilot assists the operator in steering by
  holding the wheel in autopilot mode. As a result,
  they can concentrate on the broad aspects of the
  operation. Thus, it is considered one of the most
  effective bridge navigation aids in our marine
  equipment suppliers in UAE.
• Speed Distance Measuring Equipment
• This bridge equipment on a ship is used to
  measure the speed and distance the ship has
  travelled from a given point.

8

• Navigation Lights
• According to the appropriate guidelines for the
  prevention of maritime accidents. All large/
  small boats should have nightlights as part of
  their navigation systems.
• Voyage/Route Planner
• Marine Digital route planner is used in ships to
  evade tough weather conditions and other hurdles.
  It helps you calculate the safest and most
  economical route to the port of destination.
• These are the main types of navigation equipment
  of modern ships. The advanced technologies used
  in navigation makes navigation more efficient and
  safer.
