Is it curtains for Loran?
Sally Basker
If the US decides to close Loran, will the rest of the World keep going with Loran?This question has never, to my knowledge, been put formally to the 14 other nations that provide Loran services. However, I suspect that the majority including France, Japan, Norway, the PR of China, the Russian Federation, Saudi Arabia, South Korea and the UK may see real benefit in system diversity and decide to keep Loran and transition to eLoran

The private survey set ups, most of whom are first time users of DGPS use DGPS to cut down on the time and efforts involved in surveying with electronic total station along with spirit levels.While most surveyors are aware of trilateration methods even so except for the National Survey Organisations other surveyors do not resort to trilateraties as routine
