Abstract

Methods, architectures, apparatuses, systems, devices, and computer program products directed to dead reckoning for pedestrian navigation (“pedestrian dead reckoning”) and robust heading estimation in pedestrian dead reckoning. Pursuant to the methodologies and technologies provided herein, a walking direction may be derived or otherwise determined using a robust heading estimation mechanism in connection with, for example, step detection and step length determination. The robust heading estimation mechanism may be based on device orientation (e.g., on changes in device orientation). The device orientation may be obtained based on (e.g., by way of) fusion of accelerometer and gyroscope measurements.
