Today - 8 February 2010 - sees the closure of most of the Loran-C transmitters in the US. The US Coast Guard explain that, in accordance with the US Dept of Homeland Security (DHS) Appropriations Act, they will terminate the transmission of all US Loran-C signals at 2000Z today.At that time 'the US Loran-C signal will be unusable and permanently discontinued'.This termination does not affect US participation in the handful of chains shared with Canada and Russia - but these (and all Canadian transmissions) are expected to close by 1 October 2010.It was hoped that the signals would seamlessly be replaced by eLoran transmissions, but a political impasse in the US has prevented this. The UK and Europe have been more enlightened and there is much support for eLoran to act as a terrestrial navigation and timing backup for vulnerable GNSS signals.See previous news below . .
