A method for dead reckoning parameter correction in pedestrian navigation system
IMTC 2001. Proceedings of the 18th IEEE Instrumentation and Measurement Technology Conference. Rediscovering Measurement in the Age of Informatics (Cat. No.01CH 37188), 2002 This paper presents a method for correcting dead reckoning parameters, which are heading and step size, for a pedestrian navigation system. In this method, the compass bias error and the step size error can be estimated during the period that the global positioning system (GPS) signal is available. The errors are used for correcting those parameters to

GPS-assisted Indoor Pedestrian Dead Reckoning
Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies, 2022Indoor pedestrian dead reckoning (PDR) using embedded inertial sensors in smartphones has been actively studied in the ubicomp community. However, PDR relying only on inertial sensors suffers from the accumulation of errors from the sensors. Researchers have employed various indoor landmarks detectable by smartphone sensors such as magnetic ...

Speed estimation for pedestrian dead-reckoning
21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010In this paper a new speed estimation method for pedestrian dead-reckoning is presented. The proposed approach is based on the estimated channel frequency response of Digital Video Broadcasting-Terrestrial (DVB-T) signals. Correlation coefficients are calculated from the acquired envelopes and the coherence time is estimated for a certain correlation ...

Robust Misalignment Handling in Pedestrian Dead Reckoning
2016 IEEE 84th Vehicular Technology Conference (VTC-Fall), 2016Modern mobile devices consists various sensors such as accelerometers and gyroscopes that can be used to aid and complement Global Navigation Satellite System position and velocity updates. Especially these sensors are now capable of providing good navigation solutions for pedestrians with competitive battery power consumption when compared to radio ...

Pedestrian Dead Reckoning with Turn-Based Correction
2018 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2018Pedestrian dead reckoning (PDR) is a popular localization approach. However, PDR is error prone at turning points. During a turn, a small error in heading estimation can cause severe accumulated positioning errors thereafter. In this paper, we propose a turn-based correction approach which aims to reduce the potential accumulated errors caused by ...

Strap-down Pedestrian Dead-Reckoning system
2011 International Conference on Indoor Positioning and Indoor Navigation, 2011This paper presents a waist-worn Pedestrian Dead Reckoning (PDR) System that requires minimal end-user calibration. The PDR system is based on an Inertial Measurement Unit (IMU) comprising of a tri-axial accelerometer, a tri-axial magnetometer and a tri-axial gyroscope.

Wearable indoor pedestrian dead reckoning system
Pervasive and Mobile Computing, 2010We introduce a wearable pedestrian indoor localization system with dynamic position correction. The system uniquely combines dead reckoning and fiducial marker-based localization schemes, exclusively using widely available, low end and low power consumer hardware components. The proposed system was tested with various walking patterns inside a building,
