Now They've Gone And Done It!





An AP bulletin today brought the grim news. "The plug is being pulled" was the lead sentence. In three weeks it will come to an end.


For years we heard that that this would happen, only to hear a bit later that there would be a reprieve. Now, no reprieve. They really mean it.


After over 25 years of popular use, the LORAN-C navigation system will end Monday, February 8th when most of the 24 transmission towers will be turned off, the remainder being shut down by October 1.


LORAN, the acronym for long-range-navigation, was developed for military ships and aircraft during World War II, and in 1957 a civilian version, LORAN-C was introduced. The basic system involved radio transmissions from two geographically separated towers, with the receiver measuring the time-of-arrival difference between the towers. It was extremely precise, pinpointed your exact position, your Latitude and Longitude.


I used my Ross LORAN-C for many years on the Lady Mick, eventually adding a GPS. While the GPS was far faster computing changes (LORAN-C always took a few seconds to 'catch up' if the change was severe), I always found my LORAN-C to be more accurate than the GPS when it came to getting me precisely to a waypoint or a particular spot out in the waters. I could rely on arriving sometimes within 10 yards of a target! Not bad.


While many, if not most recreational boaters headed for GPSs - - many didn't even know of LORAN-C, or else dismissed it as a technological relic, commercial fishermen seem to still use it as a trusted system. Well, not after February 8th, they won't.


The Department of Homeland Security, according to the AP, says that the elimination could save $36 million in 2010 and $190 million over five years. The US Coast Guard says it will result in eliminating 256 jobs.
