Klein Marine Radar System
Marine Radar on a Malaysian Coast Guard Ship
automatic information systems ( AIS ) or other sensors .
Some ships also have 3D displays that allow navigators to see above , below and all around the ship . In the market , names like Marconi , Wartsila , Furuno , Thales , Klein Marine and Garmin are well-known brands for marine radars . The costs of each product vary widely dependent on the specifications and brands .
Marine radar systems provide important navigation information in a variety of situations . When a vessel is within radar range of land or special radar aids to navigation , the navigator can take distances and angular bearings to charted objects and use these to establish arcs of position and lines of position on a chart .
Marine radars are a vital navigation component for safety at sea and near the shore . Seamen need to be able to manoeuvre their ships within feet in the worst of conditions and to be able to navigate blindly , when there is no visibility at night or due to bad weather . With the help of ship radar , accidents can be prevented at sea with the use of the various inherent functionalities of the radar . In addition to vessel-based marine radars , shore-based vessel traffic service radar systems in port or in harbour
are used by harbourmasters or coast guards to monitor and regulate ship movements in busy waters . A harbourmaster is the official responsible for enforcing the regulations of a particular harbour or port , in order to ensure the safety of navigation , the security of the harbour and the correct operation of the port facilities . Harbourmasters are normally responsible for issuing local safety information sometimes known as Notice to Mariners . They may also oversee the maintenance and provision of navigational aids within the port , co-ordinate responses to emergencies , inspect vessels and oversee pilotage services .
Marine radars are also used to monitor border security for controlling illegal activities such as human trafficking and smuggling activities . In future , we hope technologies will be affordable to all mariners and ships for safety reasons .
