GPS FOR MARITIME USE

Before the use of GPS in tracking ships at sea was a very difficult task. People relied heavily on radio frequency that had limited range. Today satellite tracking and communications enable the ships to communicate and be seen even when they are in the middle of the ocean, out of the reach of cellular and radio range.

GPS Navigation for Maritime Tracking

Knowing that GPS works perfectly well under open sky isn't enough to constantly track and ensure the safety of a ship at sea. The GPS transmissions from the satellites are strong, unlike in urban or forest environments where a lot of structures can block and weaken the satellites' signals. The problem lies in sending the data back to land where the people who do the monitoring of all the vessels are. Communications via cellular networks die at the range of about 10 miles from the shore. How was this remedied? Commercial Satellite Communication Services is mandatory for commercial vessels and other ships avail of this as well. The service enables the ships to communicate with land, sending voice and data from the ships' computers.

With this new capability, new regulations were developed to accurately keep track of each vessel's whereabouts. Certain specifications of ships are required to have both radio and satellite communications systems on board, and other ships are required to have Ship Security Alert Systems that sets off emergency alarms to authorities and sends the exact coordinated of the ship needing help. Zones for different equipment requirements are also mapped out. The farther you are from land, the more advanced the technology you need on your ship.

Significance of GPS Device for Maritime tracking

The primary purpose for having these systems installed is for safety. Emergency calls are just as easily done as calling through a cellular network, and the coordinates given the GPS system enables coast guards and other authorities to do speedy rescues as well. Cruise and passenger ships that transport hundreds of people across the oceans would need immediate assistance in case anything goes wrong. Oil tankers and commercial shipping lines need these because they are hot targets for criminals. Communication via satellite also ensures the safety of those in ports and bay areas by being able to confirm the ship's condition before docking.

With most of the goods are being traded through ships, it is very important to have the location of the shipments at hand. Not only will the safety of the vessels be guaranteed but also the economic stability of areas surrounding the routes of these ships.
