Abstract
A positioning system and a positioning method based on magnetic field intensity are provided. The positioning method includes: storing a magnetic fingerprint of a first place; sensing, by a mobile terminal, a magnetic field of the first place to generate sensed data; determining whether the mobile terminal is located inside or outside a vehicle according to the sensed data and the magnetic fingerprint; determining that the mobile terminal is located at a first location of the first place according to the sensed data and the magnetic fingerprint.
