Data Format key:
Date (dd.mm.yy): 22.08.98 23:06:55 Time (hr:min:sec)(in GMT), LC (fix quality)

LC just stands for Location Class. Location Classes of 0 and up are the best (derived from 4 or more messages)- a Class 0 is good to within between 1,000 and 5,000 meters. Classes 1,2,3- get consistently more accurate. The letter classes are given no estimate of error, but the A's are better than the B's etc. It appears that some of the letter class locations are pretty good (i.e. several fixes over a short period are quite similar), but then others vary wildly- especially the longitude.
