GIDAS (GNSS Interference Detection & Analysis System)

GIDAS (GNSS Interference Detection & Analysis System)

GIDAS is a scalable and flexible real-time GNSS Interference Detection & Analysis System which can be used as standalone monitoring station for interference detection and can be upgraded to a more complex network of stations which allows interference detection and interferer localisation. The system is independent from any other system and is designed to be easily deployed. Relevant user requirements and target user applications have been collected and evaluated. Based on these three different use cases have been elaborated targeting safety critical applications with either high-demands regarding interference monitoring or less stringent requirements as well as mission critical applications featuring dynamic applications. Based on the user requirements and use cases the system requirements were derived.

A single monitoring station receives all visible civil GNSS signals and automatically detects and classifies sources of intentional interference within the GNSS signal band in real time. The flexible and configurable system allows the user, based on the use case, to define which signals and bands shall be monitored and to which extent by specifying detection thresholds.

For safety critical applications with high demands, the system is capable of estimating the interference location in 2D by joining several (at least three) monitoring stations. The system is fully user configurable through a dedicated graphical user interface and provides an alarming functionality in case of appearing intentional interference sources. All detected interference events are stored in a database together with a digital signal snapshot for post-processing and inspection purposes. Currently the detailed system design is finalized and first steps regarding implementation have been made.
