GPS Technology

Global Positioning System (GPS) technology was originally developed for military use but is now widely used in engineering and everyday life.

A GPS receiver calculates its position by receiving signals from several satellites orbiting the Earth. By comparing the time taken for signals to arrive, the device can determine its exact location.

Engineers use GPS technology in many applications. For example, it helps monitor delivery vehicles, guide aircraft and ships, and measure land during surveying projects.

Modern GPS devices are extremely accurate. Because of this, manufacturers now focus on improving additional features such as reliability, battery life and ease of use.

As satellite technology improves, GPS systems will become even more useful for engineering projects around the world.
