According to the Northwest European Loran-C System (NELS) web-site, the 100kHz transmissions, which affect 136kHz reception in north-west Europe, could close at the end of 2005 when the current agreement expires. NELS is publicly funded by several European countries, and provides a positioning system for shipping in the North Sea and Eastern Atlantic. It has largely been rendered obsolete by GPS systems and a new raison d'etre for the system has to be found.
