Abstract

Provided are an apparatus and a method of correcting a moving direction of a pedestrian, which can estimate a pedestrian location accurately by correcting error components that are included in a moving direction angle, detected by a terrestrial magnetism sensor. The apparatus for correcting a pedestrian moving direction, including a signal receiving unit which estimates a pedestrian location using a satellite signal from a satellite, a sensor unit which detects a first moving direction angle using a terrestrial magnetism sensor, and a control unit which calculates a second moving direction angle using a pedestrian location estimated by using a satellite signal of good reception quality and corrects the first moving direction angle detected by the terrestrial magnetism sensor by using the calculated second moving direction angle.
