DATA NOTE: 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. (Argos Accuracy Table) 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.

Satellite data uses only degrees and decimal fractions of degrees instead of the tradition degrees, minutes, seconds for latitude and longitude to adapt to computer languages. Some computers use degrees, minutes and decimal degrees of minutes such as 48 16.5' so look at the data carefully before plotting your fixes.

example: > Lat1: 48.275N = 48 16.5'N [latitude] Lon1: 69.232W = 69 13.9'W = -69.232 [longitude]

The Map Generators in the Analysis Tools section also have an adaptation to computer languages. To input longitude, use - (negative) for West and + (positive) for East of the Greenwich Mean. Also, latitude uses - (negative) for South and + (positive) for North of the Equator.

Lon1: 69.232W = -69.232, and 48.275N = 48.275 or 48.275S = -48.275
