White paper: Protection against GNSS spoofing

With the introduction of Trimble® Maxwell™ 7 technology, Trimble has added several technical innovations that improve the performance of its receivers. This technical bulletin provides an overview of how Trimble receivers provide protection from the increasing threat of false GNSS signals.

These false or spoofed signals could potentially result in a receiver calculating positions in error by many kilometers. This is not to be confused with jamming, which also disrupts positioning by transmitting strong undesired signals that overload the GNSS receiver’s RF or signal processing.

However, in the jamming scenario, while the receiver has difficulty calculating a position, it will generally not be in the wrong location. A separate technical bulletin will describe how  Maxwell 7 technology helps overcome GNSS jamming signals.
