In the world of aquatic transport document, there are many navigation is used to help the team to get their way to Ocean.

One of the main instruments of navigation, nautical chart. A chart is a graphical representation of a marine and coastal areas around it. It can show water depths, seabed features, detailed coastal and other important data. E-card today is capable of showing 3D rendering of the different sectors, which can be viewed at any angle.

Celestial navigation instruments are used primarily to measure the height of an object in the sky of stars or the sun. They can also be used to calculate the angular distance between two objects. Examples of these units are back staff, staff of the Cross and quadrants. The timer is also used by sailors to measure the height of the bodies above the horizon.

The calendar is one of the devices used in the marine chronometer. This is used to determine when the prime ...

One popular tool is very useful for navigation, which was introduced in the mid 18 century and is still in use today Sextant. Sextant is integrated into the telescope and the angular extent and determine the latitude and longitude. This invention is attributed to Sir Isaac Newton, who invented the principle of a double-reflecting instrument.

In the past, almost all ships have a weather vane. This device indicates the direction of the wind, but is now used more as a decorative ornament on top of buildings.

Today, navigation is mostly electronic and computer-based or stand. The satellites also provide vital data for the GPS or Global Positioning System. This will help determine not only the ship's navigator for the geographical orientation of his ship, but also raises awareness of a certain area to avoid possible collisions. Take a pleasure trip in the sea, or the business is

now easy, accurate and secure. Different tools for different trades all started from humble beginnings. Depending on the needs and tasks become more complex, tools are also changing. Navigation instruments have come a long way since the days when sailors relied on celestial bodies and the wind to reach its destination.
