In this video, you can take a look at what happened when the Napoli broke her back and was run aground on the south coast of the UK.

OHB Digital Solutions GmbH develops systems for monitoring the GNSS frequency bands as well as detection, classification and localization of intentional or unintentional interference sources. Many stakeholders and applications as well as critical infrastructure providers are relying on GNSS to provide their services. Since Global Navigation Satellite Systems (GNSS) are widely used in safety and value critical applications, GIDAS detects, classifies and localizes any GNSS interference...
