Converting Loran Numbers

[Richter]

I recently acquired some loran numbers from a nice older gentleman. He was a fishing machine and was nice enough to pass them on to me. Here is the question for you navigation experts. The loran numbers are TD #'s (Time Differences) not Lat. & Longitude.
Is there any easy way to convert the TD #'s to Latitude & Longitude so I can enter them into my GPS?

Thnaks, Rich

SURE! Just post em all here on this board, and we'll help you out, right gang? [img]images/icons/wink.gif[/img]
Seriously, though... I don't know!

Richter, I think it goes like this. GPS is in degrees, minutes and thousanths of minutes. Where one degree is 60 minutes.

IE: West 124 degrees,12.050 minutes
or
West 124d 12.050'

Loran #'s are in degrees, minutes, seconds. One degree is 60 minutes, one minute is 60 seconds.

IE: West 124 degrees (d), 12 minutes ('), 3 seconds (")
or
West 124d 12' 3"

to convert just divide Loran seconds by 60 and add to the minutes


3/60 = .050

(Loran C) West 124d 12' 3" => (GPS) West 124d 12.050'

Lattitude and Longitude work the same way. Good luck.


OOPS! I didn't see time differences. The conversion I gave works for charts too. I'll load the software mentioned above and check it out. Thanks boater!
