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.
