Marine Navigation Systems Quiz

Autopilot also reduces fuel consumption as the zig-zag course is avoided. Automatic Tracking Aid (ATA) displays information about tracked targets in graphical and numerical form to create a planned plan for a safer course without ______.

Magnetic Compass is used to determine position and direction and does not have any satellite and power. Gyro Compass is used to determine position, influences of gravity and the earth's rotation to find the true north. Auto Pilot relieves the helmsman to a great extent but definitely auto pilot is not a substitute for ______.

Rate of Turn Indicator shows how fast the vessel is turning at a constant speed (useful during pilotage and maneuvering), usually displayed as number of degrees of ______.

BAROMETER is an instrument for determining the pressure of the atmosphere and hence for assisting in forecasting weather and for determining ______.

Weather Facsimile is a device used to receive weather reports then presents it as a chart (map), showing barometric high pressures, low pressures, pressure gradients, wind speed, direction, and ______.

SHIP’S WHISTLE is used for giving maneuvering and warning signals and signals in restricted visibility. To communicate with other ships, as well as to signal to those on ______.

A Bridge Navigational Watch Alarm System, abbreviated BNWAS, is an automatic system which sounds an alarm if the watch officer on the bridge of a ship falls asleep, becomes otherwise incapacitated, or is absent for too long a time. RUDDER ANGLE INDICATOR A device used to indicate the present position of the ______ blade, usually fitted in the wheelhouse, bridge wings and engine control room.

GPS provides the fastest and most accurate method for mariners to navigate, measure speed, and determine location. AIS (Automatic Identification System) It was developed to provide identification and positioning information to both vessels and shore stations. LRIT ( Long Range Tracking and Identification ) provides for the global identification and tracking of ships to enhance security of shipping and for the purposes of safety and marine environment protection. Navigational Equipment Antenna A navigational equipment antenna is a device that transmits and receives radio signals used for navigation purposes on board ships, aircraft, and vehicles. ______ ( Radio Detection andRanging) is a crucial navigational tool used for detecting and tracking objects,including other vessels,land masses,and obstacles.

Electronic Chart Display and Information system With the use of the electronic chart system, it has become easier for a ship’s navigating crew to pinpoint locations and attain directions. NAVIGATIONAL LIGHTS Navigation lights are essential tool in keeping you and your vessel safe.Nav lights allow you to see other nearby vessels,and allow other vessels to see you. ANEMOMETER/WIND VANE The Anemometer is an instrument used to measure wind speed and direction and is commonly used in meteorological monitoring, SOUND RECEPTION SYSTEM A sound reception system refers to the use of audio signals for ______.

ENGINE TELEGRAPH a communications device used on a ship for the pilot on the bridge to order engineers in the engine room to power the vessel at a certain desired speed VERY HIGH FREQUENCY is used for various communication purposes, particularly in maritime, aviation, and land-based applications. ECHO SOUNDER It is an instrument used to find out the depth of a body of water or an object below the surface by means of sound waves. VOYAGE DATA RECORDER Voyage Data Recorder (VDR) is a crucial device installed on ships to collect and store data related to a ship's voyage. BRIDGE NAVIGATIONAL WATCH ALARM SYSTEM A Bridge Navigational Watch Alarm System, abbreviated BNWAS, is an automatic system which sounds an alarm if the watch officer on the bridge of a ship falls asleep, becomes otherwise incapacitated, or is absent for too long a time. RUDDER ANGLE INDICATOR A device used to indicate the present position of the rudder blade, usually fitted in the wheelhouse, bridge wings and engine control room. ______ AND DISTANCE LOG DEVICE used to measure the speed and the distance travelled by a ship from a set point.
