The maritime domain is an increasingly complex space. Ships are getting bigger and there are more of them. They operate in an increasingly complex sea space with more off shore infrastructures and alongside growing numbers of autonomous vessels. The modern day mariner faces a rapidly evolving navigational challenge.

For these reasons the vulnerabilities of GNSS as a position, navigation and time solution are being explored by MarRINav. The project, funded by the European Space Agency, is also researching systems complementary to GNSS that add layers of integrity and resilience.
