Abstract: Disclosed herein are an indoor positioning system and method. The indoor positioning method includes generating measurement information by measuring a geomagnetic field generated from a ferromagnetic substance present in indoor space, and a slope of a user terminal device, generating declination angle information and inclination angle information using the measurement information, generating true north navigation coordinate system-based geomagnetic field vector information using the declination angle information and the inclination angle information, receiving geomagnetic field heatmap information, generated using collection information that is collected at indoor reference locations, and performing indoor positioning based on the true north navigation coordinate system-based geomagnetic field vector information and the geomagnetic field heatmap information.
