Characterisation of Radio Frequency Interference for GNSS Maritime Applications

Kurzfassung

An international maritime measurement campaign on board of a large container ship was carried out in order to detect and record radio frequency interference events in the frequency bands allocated to open services of global satellite navigation systems. The measurement set-up consists of a conformal seven elements antenna array, a data recorder system and a multi-antenna navigation receiver prototype. In this paper, the system is briefly presented, together with the proposed detection and analysis methodology. An overview of the measurement results is given, including the characteristics of the most noticeable interference events.
