: DOES ANYBODY HAVE A WEBSITE THAT YOU CAN ENTER LORAN POINTS AND FIND THE CONVERSION TO LATS AND LONGS? THANKS
If you search the old posts, you will find some info on this. Here is a recent message posted by Brendon on this topic:
I occasionally recieve requests from people who want to convert between LORAN C and GPS coordinates (LAT/LON). For reasons which I discuss in my article at http://www.execpc.com/~bbaillod/navi.html , this conversion is not advisable and yields a nonstandard error of 0 to .5 miles. The error is particularly pronounced in the Great Lakes due to land mass propogation errors inherent in LORAN C. However, I have located a decent freeware program which will perform the conversion to or from GPS or LORAN C for those who need an approximation and don't have the functionality in their current GPS or LORAN. The utility is a DOS program which may be downloaded as an executable. When the executable is run, the program is unzipped to the local directory. I have tested it and it appears to work at least as well as the conversion on my GPS. The utility can be downloaded at:
