Electronics for Marine Navigation

Navigating on the open water away from land has always been challenging and very exciting. Boating can be a very rewarding experience provided your vessel is equipped with the required tools to ensure your safety. Good quality marine navigation electronic equipment on board aids easier, faster and safer navigation.

It is recommended to make sure that, the boat is equipped with certain marine electronics. The minimum requirement for safety is to at least have a VHF Marine Radio and a compass before leaving the shore. Other desirable electronics include a GPS plotter, fish finder or depth sounder,radar, and auto pilot. Other more sophisticated but nice to have items include an Automatic Identification System and a networked navigation system

Marine navigation electronics equipment operation and uses are discussed below:

Auto Pilot: It is a highly recommended tool for mariners set to go on a long voyage. Auto Pilot helps to steer the boat automatically and thus, relieves the person at the helm from fatigue. Auto Pilot is of great aid for those that troll while fishing as it controls the boat direction automatically, allowing the captain to join and enjoy the fishing. This tool is very helpful, as it allows to save fuel by maintaining the vessel on a steady heading.

Fish finder: Those who fish for pleasure or hire enjoy the help provided by a good fish finder. The fish finder uses SONAR for its operation. In general, the sonar operates by transmittig a signal down trough the water column until it hits an object with mass, sufficent to return a signal to the device, thus drawing an image on the screen. Thereby, showing the depth of the fish in relation to bottom structure. If a fish finder is not desired or needed then a depth sounder with a digital readout is ample and less expensive.

Automatic Identification System: It is considered an important electronic tool for marine navigation. It provides other boats with your vital information as well as their information to you such as the exact position of the boat, longitude and latitude, Time stamp, Rate of turn, Course over ground etc. While the boat under way AIS shows the above information every 2 to 10 seconds, whereas when the boat is anchored, it shows the information after every 3 minutes. Apart from providing the above-mentioned information, it also provides information about other boats or ships concerning their dimension, location, and type of the boat or ship. It is the best electronic tool for collision avoidance.

EPIRB: The Emergency Position Indicating Radio Beacon (EPIRB) also known as distress radio beacon is a transmitter, which helps rescue services to locate boats in distress. The transmissions are rebroadcast from satellites around the world to the various rescue services. Watercraft operators wishing to have an EPIRB must now use a digital 406MHz unit. The International Copas-Sarsat Satellite System stopped monitoring for all but 406MHz signals for distress alert and position data for rescue operation throughout the world..

GPS Plotter: The GPS system now takes over the duty of the old Loran navigation system. GPS signals are broadcast from those satellites worldwide, that are maintained by the USA . GPS can be read in digital or map format. The preferred method is on a plotter that is loaded with digital maps of the area you are boating in. Most new VHF radios now have the capability to broadcast your location with a distress signal if connected to a GPS

Role Of Major Marine Electronics Devices

To outscore the competition for functionality and performance, a number of professional marine solution providers are available. Other than offering services related to design, installation and support, the suppliers have been serving other requirements of the yacht owners including the supply of marine electronics devices, marine electronic repair and much more.

In this article, well come to know the kind of role played by main electronics devices like Radar, Sonar, chartplotter, GPS and much more.

Chartplotter

The main role of the chartplotter is defined as displaying the Electronic Navigation Chart along with the heading, position and speed of the ship. Adding to it, the device is also responsible for the display of information collected from Radar and other sensors.

Considering technology, the chartplotter makes use of single or multiple computers and generates three-dimensional displays. Along with the larger screens, the device comes with increased processing power as well as multi-function capabilities.

SONAR

The acronym used for Sound Navigation And Ranging, SONAR is a useful technique which is meant to use sound propagation to communicate, detect or navigate objects under the surface of water. Where passive sonar is meant to listen sound made by the vessels, active sonar emit sound pulses and also listens to echoes.

The detection and performance of the SONAR is dependent on factors like the environment, transmitting equipment and receiving equipment.

RADAR

One of the most useful marine electronics devices is RADAR and its main role is to detect the range, direction, altitude or speed of the object. And that object could be guided missile, aircraft, spacecraft, ships or other motor vehicles.

Modern uses and role of the RADAR are many and chief ones are air traffic control, air-defense systems, radar astronomy, antimissile system, locate landmarks or ships. Including digital signal processing, the device comes with the capable feature of extracting objects from extreme high noise levels.

GPS

The satellite navigation system which is a space based is GPS. The main role of this system is to offer information about weather and the information is received through GPS receiver.

And problem to any of these electronic devices can cause serious life risks to the marine environment. This is the place where marine electronic repair services play a significant role. Acquiring assistance of leading marine electronic repair service providers can help one with appropriate course of action. The experts quickly diagnose the problem and get the repairs done with quality technical resources and prompt repair services.
