The technology that uses GPS for geolocation services is Location-based Services (LBS). LBS utilize the Global Positioning System to provide users with location-specific information and services, such as navigation, tracking, and location-aware applications. Examples of LBS include map applications, restaurant locators, and ride-sharing services. GPS technology plays a crucial role in enabling accurate location tracking, improving user experiences, and delivering tailored services based on real-time geolocation data.
