Marine Navigation Systems

Marine Navigation Systems

Ship navigation system that is already set in the Global Maritime Distress adan Safety System (GMDSS). The GMDSS is an international agreement in which regulate communication procedures, the procedure’s safety, as well as the types of equipment in the ship. The purpose of the agreement is to improve safety and also to make procedures easier to implement in order to avoid danger. Existing communication systems in the GMDSS indeed have been specially designed to ensure the safety and necessity of handling signaling distress in the sea and this applies to the whole world. Of course, this system has other capabilities that send and receive signals sent by the danger of another ship, the ship that affected so they can immediately get help as soon as possible. This system can also be used to study the safe route that will pass quickly and safely.

Some systems are incorporated in the GMDSS has long operated with functions as diverse as general radio communication which aims to ship communication tools through a network of terrestrial radio and safety related. Ship navigation systems such as alerting useful to give notice of a disaster or threatening danger as well as to coordinate an inter-ship aid. Tool – navigation tools that are typically used in marine vessels such as radar (radio detection and ranging), GPS (global positioning system), RDF (radio direction finder), enchosounder, AIS (automatic identification system), and many others. The navigation tool must meet the standards set by the GMDSS as to ensure the safety of the crew is in the ships.

GMDSS communication system is divided into two satellite communication systems and ground communications systems created with the aim to coordinate the danger signals between ships on the high seas. Communication is done can be within a range of short, medium, or remotely by using a specific frequency that VHF (very high), and MF (medium), and HF (high) frequency. The main function of the navigation system in the ocean is to determine the bow that can be known within a ship from origin to destination. An explanation of the navigation system briefly ships can illustrate the complexity of existing systems on ships. To that end, a driving ships and crews should be aware of the GMDSS and navigation systems used by ships dikemudikannya with the aim to prevent any unwanted bad thing. For that, it needs a deeper introduction of navigation tools such ships to know the basic things about the navigation tools that are used all ships.

Carriers most sophisticated

Carriers most sophisticated

In this modern era of many advanced technologies that have been developed or are being developed. One was in the military field. After yesterday to discuss the world’s largest warships and submarines art, the discussion this time is still the same but slightly different that the aircraft carrier.

An aircraft carrier is a war fleet which is phenomenal and fantastic, considering its function in maintaining the territorial sea of a country. Not all countries have aircraft carriers, because the cost of an aircraft carrier just to reach billions of US Dollars. The function of the carrier one of which is to bring military forces such as combat aircraft, helicopters, infantry, tanks, weaponry and so forth. Developed countries are racing to have aircraft carriers with advanced technology, the following is recorded in the history of the carrier by using advanced technology.

Carriers most sophisticated :

  • U.S.S. John F. Kennedy, United States
    U.S.S. John F. Kennedy is the most advanced aircraft carrier this one is owned by the United States. Currently aircraft carriers belonging to the US Navy no longer in operation. Carriers was once dubbed as “Big John”. Carriers U.S.S. John F. Kennedy is also able to fight with submarines, thus making it an aircraft carrier with a variety of functions. Was first launched in 1967 and ceased operations in 2007.
  • USS Nimitz, United States
    USS Nimitz is also the largest warships in the world and leads in its class. The ship was launched for a variety of missions the United States and also to secure the territorial waters of the United States. Carriers using nuclear power as a driving force, so as to be on the water for decades on one charge. The ship is capable of carrying about 85 to 95 aircraft and other equipment. The weights of these ships reached 100,000 tons.
  • Charles de Gaulle, France
    The aircraft carrier is the most advanced one belonging to the French Navy. As is the case with the USS Nimitz, an aircraft carrier which is also used as a vehicle fuel, belonging to the French aircraft carrier is capable of carrying as many as 40 fighter aircraft, heavy weapons, and able to operate for 20 years without refueling again. This aircraft carrier ever took some of the missions, including the battle with the Taliban, Afghanistan.

World’s Largest Cruise Ship

World's Largest Cruise Ship

Unlike the battleship or aircraft carrier that was used for military activities in defending the sovereignty of a country. The yacht is a luxury ship that is used for trips, in which filled with luxuries. The presence of the yacht is still a trend favorable world. The larger the size of the vessel, the greater the luxury inside. This certainly will affect rental prices climb aboard the luxury. There are many luxury yachts in the world, but what about the large size? Here is the largest cruise ships in the world, which has been summarized from various sources.

World’s Largest Cruise Ship :

  • MS Allure of the Seas
    MS Allure of the Seas is a cruise ship that was built with advanced technology, this ship is able to accommodate passengers reached 1385 people. The luxury ship is equipped with 25 restaurants, has 2000 crew who are already experts in charge of shipping. MS Allure of the Seas was built by Royal Caribbean International Company in 2006. The vessel is considered to be the largest cruise ship in the world with a length of 360 meters, and a height of 360 meters.
  • Oasis of The Seas
    Oasis of the Seas is a cruise ship next entry as one of the largest cruise ship. This ship is still considered the big brother of the ship above. This is because the ship had a difference a few inches above only by boat. Oasis of the Seas can accommodate as many as 6,000 passengers. There are a variety of luxurious amenities inside it like a nightclub, a swimming pool, bar, mini-golf, volleyball courts, and much more. The ship is expected to reach 1.4 billion dollars.
  • Freedom of The Seas
    This ship was never occupy the top positions in the world’s largest cruise ship, prior to the construction of both ships above. This luxury yacht has a luxurious facilities in it like a 3D cinema, water park, WiFi, and many other luxury amenities. Freedom of the Seas is capable of carrying passengers 4600 people, including the crew. Costs incurred to build luxury ship is 800 million dollars. This luxury ship built by the Royal Caribbean International, as well as the second ship above.

Unmanned Submarine Technology

Unmanned Submarine Technology

US defense research center DARPA back to create an unmanned submarine. This ship is controlled from the ground and dive until weeks or even months to span thousands of miles.The submarine has a length of 132feet and uses diesel-powered engines built by defense contractors Leidos United States under DARPA program. Thesubmarine is deliberately created with the aim to track the whereabouts of other submarines. Thanks to the ability of the submarine to detect other vessels, DARPA team gave him the name of Sea Hunters. However, these submarines can also be used for other purposes, because it has a large payload capacity.

The DARPA team also explained that if they really – really want to make all of the system is automated, the most difficult thing is to make a system that is able to follow the rules of the international convention for preventing collisions at sea. In other words means that these submarines in the future should be able to behave likehumans where if the government gave the order to stop to wait for another ship passing within a certain time, then the submarines should be able to stop such people who are doing the queue.Not only is it in order to operate automatically submarines must be detected by the driver of the other ship.

This submarine will be sent to SanDiego to do further testing for 2 years. Tests include whether the submarine is able to work properly identify another submarine or not. Another submarine detection automatically uses sophisticated radar and identification systems.But the submarine is still in need of assistance manually by the operator will assist observes the area around with a camera.
