The number of small sophisticated wireless sensors which share the electromagnetic
spectrum is expected to grow rapidly over the next decade and interference between these …

The Global Positioning System (GPS) is a satellite-based navigation system which allows
the user to determine position and time with high precision. However, phase measurements …

This work investigates whether it is possible to directionally spoof one GPS receiver over a
distance. Spoofing GPS signals is known to work, but other GPS receivers that are in range …

(57) ABSTRACT A magnetic resonance imaging (MRI) system (100, 400, 500) includes a
wireless RF station (20, 320, 420, 520, 620) which is associated with one or more RF coils …

GPS receivers have been profitably employed by researchers for investigations into
ionospheric and atmospheric science. However, a number of improvements in measurement …

Nowadays an increasing demand to use mobile telephones devices in aircraft flights is
being acknowledged, both in commercial and in aviation general flights. 2G and 3G mobile …

Positioning systems are one of the cornerstones of today's technology. Accuracy and
continuity of location information are crucial for military and civilian applications where GPS …

In this paper, a behavioral framework is proposed to solve dynamic GNSS positioning
problems, which in the mean time may also provide a way to determine the DOP (dilution of …

The Earth's ionosphere plays a crucial role in Global Positioning System (GPS) accuracy
because his layer represents the largest source of positioning error for the users of the GPS …

Abstract [eng] Unmanned Arial Vehicles (UAV) utilize GNSS receivers as the main
navigation instrument, in ideal conditions receiver works sufficiently well to ensure safe …
