Radar Navigation Equipment


There is a range of navigation of radar navigation equipment which Engineers recommend on marine vessels. They include; sound signaling devices and appliances, radar reflector, navigation lights and charts. Others are magnetic compass, maps and topographic maps. These radar equipment do not appear to be fundamental like other sophisticated equipment for the operation like the engine. However, the designers of the vessels cannot ignore them noting that they ensure that the boats and ships do not collide especially at night.

Sound signaling devices and appliances just as its name goes are used for  signaling for the other vessels to notice that there is a vessel around(Skolnik, 2001). They are of crucial use in situations of low visibility. They are also used to signal other vessels in case of an emergency. Radar reflectors are also used as radar navigation equipment for safety reasons. For them to  serve the purpose they have to get well placed on a vessel. In addition it has to be big enough so that it can be visible. They are more necessary on small marine boats . This is so that larger vessels can be able to spot them. Engineers recommend that a boat be equipped with the biggest reflector possible. They need to be placed at a higher height where they cannot get immersed into the water.

Navigation light is another key equipment among the radar navigation apparatus. A vessel is able to produce different light colours. The colour determines which vessel will move first when they encounter each other(Skolnik, 2001). Nevertheless, navigation lights are used throughout with a mandatory light during the day. During the night the lights are more important because of visibility. The lights are located at a point where others can see them. The size of the lights depends on the particular vessel.

Magnetic compass and charts help in providing bearings and ranges which are important in the marine for giving directions(Skolnik, 2001). Radar range works by helping to establish the line that a vessel should follow from a certain position to the other. It is placed on a chart for which the direction and the distance are shown. This is whether on land or in water. There are several radar fixes which have been identified which include the self explanatory. Also there is the bearing to the single object as well as two or more bearings. Similarly, noted are the tangent bearings and two or more ranges. Radar navigation equipments have been used for a very long period of time and they have proved to be useful. The magnetic compass is used at low visibility for keeping other magnetic materials like magnetic screw drivers away from the compass (Skolnik, 2001). It works by utilizing power from electrical and metallic sources. The charts are designed by experts from the marine and navigation departments.

Topographical maps are also designed   by specialists from marine and navigation departments (Skolnik, 2001). They show the possible obstacles on the path of a marine vessel. Such obstacles include rocks, artificial features, elevation contours among others. However, they do not show the situation under water.


The designers of a boat and other marine vessels either insert the radar equipments or leave a space for it.  The owners of the vessels should put all the radar equipments because they enhance the visibility of the boat especially at night. They prevent any possible collision and therefore they need to be put in a position where they will be of maximum use.
