Will jammers affect all smart devices?

This working paper published by Inside GNSS is the excellent work of a group of satellite experts. It encourages the use of complex antennas with GPS / GNSS receivers to significantly reduce the threat of identity theft. We totally agree. Users can use many other devices and programs that also help withstand interference and deception from wifi jammer. Unfortunately, not many users are willing to spend the time and money trying to hire them.

A reliable countermeasure against identity theft is to detect the direction of arrival using a rotating GNSS antenna that uses synthetic aperture processing and adaptive beamforming algorithms. This GNSS receiver / antenna system not only increases the flexibility of the GNSS reference network, which is very susceptible to sophisticated spoofing attacks, it also allows us to more accurately locate the spoofer. It is also an excellent tool for studying the reflection of GNSS signals.

The generation and transmission of false GNSS signals (known as spoofing) is the main threat to GNSS. In recent years this type of deception has attracted widespread attention, but has not yet found a conclusive assessment or reliable countermeasures. This article summarizes experiences made with one or two broadcast antennas for true identity theft attacks. They are implemented using an improved GNSS radio frequency (RF) signal generator.

Synthetic aperture antennas can even reliably detect and ward off complex spoofing attacks against global navigation satellite systems. Direction of arrival is a reliable metric that can distinguish spoofing signals from line of sight (LOS) signals and locate one or more spoofers with a high angular resolution of 2 degrees.
