Abstract
An access point (AP), a mobile terminal, a global navigation satellite system (GNSS), and a method of providing position information using the AP are provided. The AP may be equipped with or connected to a GNSS receiver, and the GNSS may precisely determine the position of the mobile terminal using auxiliary satellite navigation information that is generated by the GNSS receiver.
