All
personnel at Jan Mayen except those who work with
meteorological observations, are working for FTD. The main task for FTD is to run Olonkin
City, the Loran C-unit, and the service systems needed for the crew.
The Loran C-unit is delivering signals to a world-wide navigation system. In fact the Jan Mayen - unit can brag of the fact that they are among the most reliable in the world as far as I know.
During the last years, running the transmitters is getting more and more automatic and remote controlled, but the need of a highly skilled crew is still crucial.
