In the recent past, we have witnessed the adoption of different machine learning techniques
for indoor positioning applications using WiFi, Bluetooth and other technologies. The …

The research and use of positioning and navigation technologies outdoors has seen a
steady and exponential growth. Based on this success, there have been attempts to …

This paper presents the state-of-the-art and reviews the state-of-research of acoustic
sensors used for a variety of navigation and guidance applications on air and surface …

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 …

Fingerprinting based positioning is commonly used for indoor positioning. In this method,
initially a radio map is created using Received Signal Strength (RSS) values that are …

Seamless positioning and navigation requires an integration of outdoor and indoor
positioning systems. Until recently, these systems mostly function in-silos. Though GNSS …

In many scenarios, unmanned aerial vehicles (UAVs), aka drones, need to have the
capability of autonomous flight to carry out their missions successfully. In order to fly …

A general view on the problem of designing atypical battery-free, autonomous semi-passive
RFID transponders-sensors (autonomous sensors with RFID interfaces) is presented in this …

Finding the position of a radiative source based on time-difference-of-arrival (TDOA)
measurements from spatially separated receivers has been widely applied in sonar, radar …

Ultrasonic-based distance measurements using time-of-flight (TOF) is a fundamental
technique for different applications across a wide variety of fields. In general, cross …
