Time-of-Arrival Measurements

2018
For a radiolocation system the position of an object is determined using some characteristic of the radio frequency signal. These characteristics could include the signal strength, the signal phase (for angle of arrival measurements) or the propagation time-of-flight (TOF) from the transmitter to the receive.

Indoor distance estimation by using time of arrival

2018 26th Signal Processing and Communications Applications Conference (SIU), 2018
Nowadays, researches about indoor positioning is very popular. Estimating location of a communication node can be used in navigation in a shopping mall or tracking in a work place, etc. In applications without a reference point, relative location of the nodes is preferred.

Time of Arrival in Quantum Mechanics

Annals of Physics, 1995
Abstract An expression for the quantum time of arrival based on the current density is discussed and justified operationally by means of complex potentials that absorb the incoming wave in a finite distance without reflection or transmission. Previous arguments denying the possibility of defining the time of arrival in quantum mechanics are refuted.

A Channel Model for Indoor Time-of-Arrival Ranging

IEEE Transactions on Wireless Communications, 2020
We executed an indoor measurement campaign to statistically characterize the bias in time of arrival (ToA) estimates incurred by multipath in the 5.5 GHz industrial, scientific and medical band by transmitting 10 and 100 MHz bandwidth waveforms.

Intelligent time of arrival estimation

2011 IEEE Forum on Integrated and Sustainable Transportation Systems, 2011
Traditional time-of-arrival estimation techniques are often used in advanced transportation systems such as in-car navigation systems and fleet management systems. These techniques tend to neglect certain categories of context when estimating a vehicle's time-of-arrival at a given destination. Particularly important categories of such neglected context

Timing the arrival at 2340 m altitude for aerobic performance

Scandinavian Journal of Medicine & Science in Sports, 2007
This study tested the hypothesis that maximal oxygen uptake (V̇O2max) and performance increase upon altitude acclimatization at moderate altitude. Eight elite cyclists were studied at sea level, and after 1 (Day 1), 7 (Day 7), 14 (Day 14) and 21 (Day 21) days of exposure to 2340 m.

POSITION FIXING BY TIME OF ARRIVAL

1966
Abstract : An engineering model is developed of the error contours encountered in position fixing using synchronous time of arrival data. Normal distribution is emphasized. Probabilities of fixes occurring within circles and ellipses are determined using the natural oblique coordinates associated with the measuring system. Comparisons are made of three-
