Who's Afraid of the Spoofer? GPS/GNSS Spoofing Detection via Automatic Gain Control (AGC)
Abstract
The idea of Global Positioning System (GPS)/Global Navigation Satellite System (GNSS) “spoofing,” or the ability to mislead a satellite navigation receiver into establishing a position or time fix which is incorrect, has been gaining attention as spoofing has become more sophisticated. Various techniques have been proposed to enable detection if a receiver is being spoofed – with varying degrees of success and computational complexity. In this paper, a monitor in the Radio Frequency (RF) front end using the automatic gain control (AGC) mechanism is outlined. It has low computational complexity and is an extremely powerful means to detect spoofing, making spoofing no more of a threat than the much less sophisticated radio frequency interference/jamming. The technique is validated using live testing. Copyright © 2012 Institute of Navigation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
