What does the acronym 'GPS' stand for?

The acronym 'GPS' stands for Global Positioning System, which is a satellite-based navigation system used worldwide. It allows users to determine their precise location (latitude, longitude, and altitude) anywhere on Earth, provided they have a clear line of sight to multiple satellites. The system functions through a network of satellites that continuously transmit their location and time data.

This information is used by GPS receivers to triangulate the user's position, making it an invaluable tool for aviation, navigation, and various other applications that require accurate geographical positioning. Understanding the term's correct definition is crucial, especially in the context of aviation, where precise navigation is essential for safety and efficiency. Other options, while they may sound somewhat related, do not accurately capture the purpose and technology behind GPS.
