Navigation is the process of planning, recording, and controlling the movement of a craft or vehicle from one place to another. It involves using tools, such as maps, compasses, GPS systems, and knowledge of celestial bodies, to determine direction and navigate the Earth's surface, the sea, or the sky.
Types of Navigation
There are several methods of navigation, including:
Land Navigation: This involves using maps, compasses, landmarks, and GPS systems to navigate on land.
Marine Navigation: Navigating ships and boats across bodies of water using nautical charts, compasses, and electronic navigation systems.
Celestial Navigation: Using the sun, moon, stars, and planets to determine a position and course on the Earth.
Air Navigation: Piloting and navigating aircraft through the sky using instruments, radio navigation aids, and GPS systems.
Tools of Navigation
Various tools are used in navigation, including:
Maps: Visual representation of an area, showing geographical features, roads, and landmarks.
Compass: An instrument for determining directions, often using the Earth'smagnetic field.
GPS (Global Positioning System): A satellite-based navigation system that provides location and time information anywhere on Earth.
Sextant: A tool used in celestial navigation to measure the angle between a celestial body and the horizon.
Chronometer: A highly accurate clock used for determining longitude at sea.
Study Guide
To understand navigation, it is important to study the following topics:
The student develops an understanding of the processes of science by asking questions, predicting, observing, describing, measuring, classifying, making generalizations, inferring and communicating.
