Global Positioning System (GPS) services enable devices to receive signals from satellites, allowing them to calculate their exact position on Earth. This technology is widely used in navigational apps and other location-based services. Cellular location services estimate position based on the proximity to cell towers, which is less precise than GPS. While Bluetooth can be used for location services indoors, it does not offer widespread geographic positioning. NFC is used for close-range communication, not location services. WiFi is used for local area networking, and though it can assist in location determination, it is not primarily used for precise geographic positioning.
