What is jamming GNSS?

What is Jamming? Global Navigation Satellite System (GNSS) refers to a constellation of satellites providing signals from space that transmit positioning and timing data to GNSS receivers. The receivers then use this data to determine location. By definition, GNSS provides global coverage.

Are GNSS receivers effective against jamming and spoofing?

The use of GNSS receivers which are robust against jamming and spoofing is key to trustworthy data capture anytime, anywhere. Both jamming and spoofing are a type of GNSS radio interference that happens when weak GNSS signals are overpowered by stronger radio signals on the same frequency.

What is a GPS jamming device?

A jammer is a device that confuses the receiver by emitting radio signals at the same frequency as the GPS. This interference hampers the ability of the GPS device to determine its correct position. A GPS jamming unit is generally small and self-contained, so the user can readily transport and hide it.

Can a GNSS receiver Jam a signal based on TDM?

In this system model jamming signal is superposed with GNSS signals at the antenna of GNSS receiver. The aim of this system model is to show that by using jamming waveform based on TDM, it is possible to successfully jam receivers of GNSS, and that it is not necessary to jam continuously all frequency bands of interest (Fig.2).
