Ces technologies peuvent améliorer l'utilité des informations de positionnement GPS.

The Global Positioning System (GPS), originally Navstar GPS(stylized in capital letters in its logo), is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Obstacles such as mountains and buildings block the relatively weak GPS signals.

The GPS does not require the to transmit any data, and it operates independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the GPS positioning information. The GPS provides critical positioning capabilities to military, civil, and commercial s around the world. The United States government created the system, maintains it, and makes it freely accessible to anyone with a GPS receiver.
