Maritime Resilient PNT in Europe… Where Now?

Martin Bransby, Paul Williams

Abstract:	For the last decade, the General Lighthouse Authorities of the UK and Ireland (GLA) have been exploring the use of eLoran as a backup for GNSS in the maritime positioning domain. Although a great deal has been theorised, developed, proved and trialled from a technical perspective, it seems that this was not enough to implement this system in Europe on a regional basis due to the lack of political will and understanding of GNSS vulnerabilities. Whilst undertaking the eLoran project, the GLA have also been involved in the potential development of other, non-satellite based, alternative systems. It seems that these now will form the basis of positioning resiliency either individually, or as a tapestry of systems serving the maritime navigator in Europe. This paper explores the failure of eLoran on a non-technical basis, what happens next and what we are aiming to develop now and in the future to protect the maritime navigator in the face of increasing GNSS outages.
