Hybrid Tdoa/aoa Method for Indoor Positioning Systems
We propose a hybrid time difference of arrival (TDOA) / angle of arrival (AOA) method for indoor positioning systems. The combined AOA includes both the azimuth AOA (A-AOA) and elevation AOA (E-AOA). Thus, this method makes full use of the AOA information to minimize the errors due to estimation of multipath parameters and gives the position of the estimated mobile terminals by simultaneously r...
متن کاملA Hybrid TDOA/AOA Positioning Technique for Indoor UWB Systems
A hybrid TDOA/AOA positioning technique for indoor ultra wideband (UWB) systems is presented in this paper. The UWB system is a potential candidate for improving the location accuracy of indoor positioning due to the fine-resolution characteristic of the UWB signals. The hybrid technique consists of extended Kalman filters (EKF’s), which process time difference of arrival (TDOA) and angle of ar...
متن کاملAn Indoor Positioning System Based on Wi-Fi for Energy Management in Smart Buildings
To offer indoor services to occupants in the context of smart buildings, it is necessary to consider information concerning to the identity and location of the occupants. This paper proposes an indoor positioning system (IPS) based on Wi-Fi fingerprint and K-nearest neighbors (KNN) method. The positioning of a mobile device (MD) using Wi-Fi technology involves online and offline phases. In this...
متن کاملNextechs Indoor Positioning System
The Nextechs Indoor Positioning System (NIPS) is an UWB based system for high resolution, high accuracy, 3D location of objects indoor. The system consists of an infrastructure of fixed, active objects called NODES that perform ranging measurements with the objects that are to be located, called TARGETS. Signal time of flight (tof) from nodes to targets is measured in order to compute distances...
متن کاملA Smartphone Indoor Positioning Method
Location based services are very useful to human beings. The vehicle navigation service that is used by almost all drivers in the world is an example location based service. As the man made constructions are getting bigger and bigger, indoor location based services are demanded. Matter of fact, researches for indoor location based service started in the early 1990s and developing techniques wit...
