Experimental evaluation of UWB indoor positioning for indoor track cycling [PDF]

open access: yes, 2019
Accurate radio frequency (RF)-based indoor localization systems are more and more applied during sports. The most accurate RF-based localization systems use ultra-wideband (UWB) technology; this is why this technology is the most prevalent.

Observation Model for Indoor Positioning [PDF]

open access: yesSensors, 2020
The IEEE 802.11mc WiFi standard provides a protocol for a cellphone to measure its distance from WiFi access points (APs). The position of the cellphone can then be estimated from the reported distances using known positions of the APs. There are several “multilateration” methods that work in relatively open environments.

An RFID Indoor Positioning Algorithm Based on Bayesian Probability and K-Nearest Neighbor

open access: yesSensors, 2017
The Global Positioning System (GPS) is widely used in outdoor environmental positioning. However, GPS cannot support indoor positioning because there is no signal for positioning in an indoor environment. Nowadays, there are many situations which require

Scaling Indoor Positioning

open access: yes, 2023
Our phones have many uses for positioning technologies, such as navigation, LocationBased Services (LBS), emergency positioning, fitness applications, and advertising. We trust our phones and wearables to be location-aware. However, as soon as we enter a building, we can no longer use GPS signals, as their already weak signals are well below the ...

WiFi-RTT Indoor Positioning [PDF]

open access: yes2020 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2020
Global navigation satellite systems (GNSSs) can deliver very good position estimates under optimum conditions. However, especially in urban and indoor scenarios with severe multipath propagation and blocking of satellites by buildings the accuracy loss can be very large. Using WiFi for indoor positioning is a common approach because WiFi infrastructure
