UWB-Based Indoor Positioning System With Infinite Scalability

open access: yesIEEE Transactions on Instrumentation and Measurement, 2023
The ultrawideband (UWB) radio technology is currently considered the de facto standard for implementing precise indoor positioning systems. Several positioning algorithms are currently being investigated for finding the best implementation in terms of ...

A Novel NLOS Error Compensation Method Based IMU for UWB Indoor Positioning System

IEEE Sensors Journal, 2021
Electromagnetic wave is susceptible to the multipath effect, especially in complex indoor environment. As transmission of non-line of sight (NLOS), it leads to bigger measurement error, which makes positioning accuracy decline.

Hybrid Indoor Positioning System for Pedestrians With Swinging Arms Based on Smartphone IMU and RSSI of BLE

IEEE Transactions on Instrumentation and Measurement, 2021
Over the last decades, researchers have invented many positioning algorithms for pedestrians in the indoor environment, such as trilateration, fingerprint, and pedestrian dead reckoning (PDR) system.

Bayesian indoor positioning systems

Proceedings IEEE 24th Annual Joint Conference of the IEEE Computer and Communications Societies., 2005
In this paper, we introduce a new approach to location estimation where, instead of locating a single client, we simultaneously locate a set of wireless clients. We present a Bayesian hierarchical model for indoor location estimation in wireless networks.
