Cooperative angle-of-arrival position localization

Measurement, 2015
Abstract Cooperation among unknown-location nodes can improve network positioning coverage as well as localization accuracy particularly in the poor electronic conditions. This paper investigates the cooperative angle-of-arrival (AOA) positioning based on the Ultra Wideband (UWB) technique.

Robust Navigation Using Angle of Arrival Measurements

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation
The majority of conventional radionavigation systems are based on Time of Arrival (TOA) measurements of RF signals. By far the most common method is pseudoranging, mainly a result of the undisputed success of Global Navigation Satellite Systems (GNSS) as a ubiquitous technology, especially in aviation.

Two-dimensional angle of arrival fluctuations

The Journal of the Acoustical Society of America, 1996
Angle of arrival fluctuations are one manifestation of acoustic propagation through a turbulent flow. Here the two-dimensional angle of arrival distribution for a 670-m acoustic path through a high Reynolds number flow in a tidal channel is examined and its origin and relationship to the flow field is determined.

Network localization using angle of arrival

2008 IEEE International Conference on Electro/Information Technology, 2008
In this paper, we propose two localization methods using angle of arrival (AoA) information. We assume that nodespsila axis orientations are unknown. Therefore, all AoA measurements are employed to calculate the angle differences of two different nodes viewed by the third one.

The elevation angle of mobile radio signal arrival

IEEE Transactions on Vehicular Technology, 1973
Field measurements of mobile radio signals have shown that signal arrival is concentrated in elevation angles lower than 16°. This suggests use of an omnidirectional antenna with vertical directivity, instead of the usual whip antenna, to increase average signal strength as a further improvement in the advantages of diversity reception.
