A Novel 3D Multilateration Sensor Using Distributed Ultrasonic Beacons for Indoor Navigation

A Novel 3D Multilateration Sensor Using Distributed Ultrasonic Beacons for Indoor Navigation

Navigation and guidance systems are a critical part of any autonomous vehicle. In this paper, a novel sensor grid using 40 KHz ultrasonic transmitters is presented for adoption in indoor 3D positioning applications. In the proposed technique, a vehicle measures the arrival time of incoming ultrasonic signals and calculates the position without broadcasting to the grid. This system allows for co...

designing and implementing a 3D indoor navigation web application

​During the recent years, the need arises for indoor navigation systems for guidance of a client in natural hazards and fire, due to the fact that human settlements have been complicating. This research paper aims to design and implement a visual indoor navigation web application. The designed system processes CityGML data model automatically and then, extracts semantic, topologic and geometric...

A Novel UWB-based Multilateration Technique for Indoor Localisation

In this paper, we present a novel geometrically driven multilateration technique that is based on Ultra-Wideband (UWB) technology. We refer to our proposed solution as Time Reflection of Arrival (TROA). We demonstrate in this paper that the position estimation error is improved upon by carefully considering the inherent properties of the UWB technology and the reflection properties of transmitt...

Autonomous Navigation of Indoor Mobile Robot Using Global Ultrasonic System

Indoor Navigation System for Mobile Robot using Wireless Sensor Network

We describe an algorithm for indoor mobile robot navigation using wireless sensor network. In our navigation system, a robot can navigate autonomously without the need for a map, a compass, or GPS. We use only several sensor nodes with ultrasonic sensors. Sensor nodes are deployed in an indoor environment and each sensor node has routing paths to all available destination-nodes through flooding...
