What is the primary function of the Global Positioning System (GPS)?

The primary function of the Global Positioning System (GPS) is to provide location coordinates. GPS is a satellite-based navigation system that allows a GPS receiver to determine its precise location (latitude, longitude, and altitude) anywhere on Earth. By receiving signals from a network of satellites, the GPS receiver can triangulate its position using the time it takes for the satellite signals to reach the receiver, thus enabling accurate location determination.

While it is true that GPS systems also provide synchronization data that can be used for time signals, the main and most recognized purpose of GPS is to offer accurate location information, which is utilized in various applications such as navigation, mapping, and tracking.
