Spirent Communications has announced the GSS200D an Interference Detection and Analysis solution for GNSS frequencies. Together with Nottingham Scientific Limited they have developed a solution that consists of field-based hardware and a secure data server for automatic capture and analysis of global navigation satellite system (GNSS) radio frequency interference. Deployments of GSS200D probes readily provide users with a thorough understanding of the RF interference environment at sites of interest.
The GSS200D is a newer version of the GSS100D which has been used to detect GPS L1 interference events in the past. This new version supports additional frequencies and constellations, as well as improves the analysis and reporting of results. The GSS200D responds to the demand of critical infrastructure and civil aviation customers.
The GSS200D is the first automated solution to identify and securely store multi-constellation GNSS RF interference. The data server tools enable trend analysis and event identification over time, as well as re-generation of real world events. This solution offers unique value because it enables informed decision making in areas such as site selection and approaches to make devices and systems more robust in the face of increasing threats that simply cannot be eliminated.
This is the world’s first detection system that can simultaneously operate on GPS, GLONASS and GALILEO in the L1 band. This functionality enables a wide range of users, such as critical infrastructure communications, broadcast and power distribution, civil aviation, road user charging and autonomous vehicles to detect, characterize and classify RFI sources that may affect their services.
RF Interference events captured by the GSS200D are logged and stored in the PT Cloud, the secure cloud infrastructure provided by Spirent. Users can access this information via a web portal and use analytics/reporting features that include visualization of both spectrogram and spectrum, as well as characterization of the type and priority of interferences, enabling monitoring over time and in-depth trend analysis. On-premise server options are also available.
