The technology that aids in location tracking applications primarily involves Global Positioning System (GPS) technology. GPS receivers use signals from a network of satellites orbiting the Earth to determine precise geographic locations. This technology is integral to location-based services, enabling features like navigation, geofencing, and real-time tracking. Additionally, mobile devices may utilize other positioning methods, such as Wi-Fi triangulation and cellular networks, to enhance tracking accuracy indoors or in environments where GPS signals may be weak.
