Indoor Positioning System with UWB Based on a Digital Twin [PDF]

open access: yesSensors, 2022
Ultra-wideband (UWB) technology is used for indoor positioning, but its positioning accuracy is usually degenerated by various obstacles in the indoor environment because of non-line-of-sight (NLOS).

Fuzzy Logic Indoor Positioning System

open access: yesInternational Journal of Interactive Multimedia and Artificial Intelligence, 2008
The GPS system is not valid for positioning indoors, thus positioning systems are designed using Wi-Fi technology that allows location of a device inside buildings. The use of fuzzy logic is argued by the failure to find positioning systems based on this

Collaborative Indoor Positioning Systems: A Systematic Review [PDF]

open access: yesSensors, 2021
Research and development in Collaborative Indoor Positioning Systems (CIPSs) is growing steadily due to their potential to improve on the performance of their non-collaborative counterparts. In contrast to the outdoors scenario, where Global Navigation Satellite System is widely adopted, in (collaborative) indoor positioning systems a large variety of ...
