Navigation

Navigation is the process of determining and controlling the position and direction of a vehicle or vessel. It can be done using various methods and tools, including celestial navigation, GPS (Global Positioning System), and maps.

Celestial Navigation

Celestial navigation is the use of celestial bodies such as the sun, moon, and stars to determine the position and direction of a vehicle. It involves measuring the angle between the celestial body and the horizon to calculate the position of the vehicle. This method has been used for centuries by sailors and navigators.

GPS (Global Positioning System)

GPS is a satellite-based navigation system that provides location and time information anywhere on or near the Earth. It works by using a network of satellites to determine the receiver's position through trilateration. GPS is commonly used in modern navigation systems for cars, ships, and aircraft.

Maps

Maps are visual representations of the Earth's surface or a region, showing geographical features, roads, and landmarks. They are essential tools for navigation, providing information about the relative positions of different locations and the best routes to take.

Study Guide
