US 2026/0160897 A1 · GLOBAL NAVIGATION SATELLITE SYSTEM JAMMING AND SPOOFING DETECTION APPARATUS AND METHOD

Abstract

An apparatus for detecting global navigation satellite system (GNSS) spoofing and jamming in a moving asset includes an intake module configured to receive position data relating to the moving asset from multiple position data sources and to generate formatted position data based on the received position data. The apparatus further includes a spoofing and jamming detection module coupled to the intake module. The spoofing and jamming detection module is configured: to receive the formatted position data, the formatted position data including GNSS information relating to the moving asset from a first position data source of the multiple position data sources; to determine whether a received GNSS signal is degraded based on the GNSS information received from the first position data source; and to generate a GNSS jamming alert and/or a GNSS spoofing alert when a degradation of the GNSS signal exceeds a first prescribed threshold.

Dependent claims

An apparatus for detecting global navigation satellite system (GNSS) spoofing and jamming in a moving asset, the apparatus comprising:

an intake module, the intake module configured to receive position data relating to the moving asset from a plurality of position data sources and to generate formatted position data based on the received position data;
and
a spoofing and jamming detection module operatively coupled to the intake module, the spoofing and jamming detection module configured:
to receive the formatted position data, the formatted position data including GNSS information relating to the moving asset from a first position data source of the plurality of position data sources;
to determine whether a received GNSS signal is degraded based on the GNSS information received from the first position data source;
and
to generate at least one of a GNSS jamming alert or a GNSS spoofing alert when a degradation of the GNSS signal exceeds a first prescribed threshold.

An apparatus for detecting global navigation satellite system (GNSS) spoofing and jamming in a moving asset, the apparatus comprising:

an intake module, the intake module configured to receive position data relating to the moving asset from a received radio frequency (RF) GNSS signal and to format an analog waveform from the received RF GNSS signal into a corresponding digital signal;
an RF signal processing unit operatively coupled to the intake module, the RF signal processing unit being configured to receive the digital signal provided by the intake module and to extract metadata from the digital signal;
and
a spoofing and jamming detection module operatively coupled to the RF signal processing unit,
wherein the metadata extracted by the RF signal processing unit comprises information used to determine a state of a global positioning system (GPS) RF state processing unit in the spoofing and jamming detection module, and
wherein the GPS RF state processing unit is configured to generate an output signal indicative of a presence of a jamming and/or spoofing event, based at least in part on the metadata extracted by the RF signal processing unit.
