This work proposes the use of a hybrid acoustic and optical indoor positioning system for the
accurate 3D positioning of Unmanned Aerial Vehicles (UAVs). The acoustic module of this …

Acoustic local positioning systems (ALPSs) are an interesting alternative for indoor
positioning due to certain advantages over other approaches, including their relatively high …

Indoor positioning technology is the key to achieving seamless indoor/outdoor location-
based services (LBSs). As typical nonlinear information, pedestrian accessibility improves …

To achieve high precision and robust positioning on mobile devices, we propose a novel
audio signal arrival time detection algorithm consisting of both coarse and fine searches. A …

This paper proposes an analysis of the quasistationary magnetic field generated by coils
and its applicability to 3-D short-range positioning scenarios. Starting from a theoretical …

Many distributed systems that perform indoor positioning are often based on ultrasound
signals and time domain measurements exchanged between low-cost ultrasound …

Indoor location positioning techniques have experienced a significant growth in recent
years. This work presents a hybrid indoor positioning system with fine and coarse modes. It …

In this paper we present a mobile application and solution for accurate smart indoor
