Navigation also refers to the specialised knowledge used by navigators to perform navigational tasks. Navigational techniques involve locating positions compared to known locations and patterns as well as determining the distance between places.
Modern navigation rely on satellites to determine positions and to travel by sea and by air. Trigonometry is fundamental to navigation. Trigonometry is used extensively in calculations referring to Cartesian coordinates. Cartesian coordinates are used to represent North, South, East and West directions. A compass is a navigational instrument that shows four direction points. These points are North, South, East and West.
Compasses are essential in Navigation for it determines bearings and which way to travel. Before the compass, the position and direction at sea was done by the sighting of landmarks and celestial bodies stars. The invention of the compass enabled a heading to be determined when bad weather occurred in addition to latitude and longitude.
This precision clock kept accurate time on a boat, and sailors could at last determine longitude. They could do this by calculating the difference between the time on their ship and the time at a fixed land position.
Navigators today apply spherical trigonometry to measure time and determine longitude. Enjoy this short animation video that summarizes the history of sailing navigation:. Follow us for the latest.
