GPS Technology

Definition

GPS technology, or Global Positioning System technology, is a satellite-based navigation system that provides accurate location and time information anywhere on Earth. It works through a network of satellites that transmit signals to GPS receivers, allowing users to determine their precise position, which plays a crucial role in various sectors such as transportation, logistics, and mobile applications.

5 Must Know Facts For Your Next Test

1. GPS technology was originally developed by the U.S. Department of Defense for military navigation but has since been widely adopted for civilian use.
2. The system consists of at least 24 satellites orbiting the Earth that ensure coverage anywhere on the globe.
3. GPS technology allows for real-time tracking, which has transformed industries like logistics and delivery by improving efficiency and accuracy.
4. Applications of GPS extend beyond navigation; they include mapping, land surveying, and even agriculture for precision farming.
5. The accuracy of GPS can be affected by environmental factors like buildings, trees, and atmospheric conditions, leading to potential errors in positioning.

Review Questions

• How does GPS technology function and what are its primary components?
  • GPS technology operates by utilizing a network of satellites that transmit signals to receivers on Earth. The receivers calculate their position based on the time it takes for the signals from at least four satellites to reach them. This triangulation process allows users to determine their exact location and is fundamental for navigation purposes.
