NO they are not always accurate. If you look at some fixes from the blue
whale data especially they are on land. The satellite has to get at least
three good signals from the tag on a single pass to get a good location.
If you look at some of our informational links on sat tags you can see how
the accuracy is determined and indicated on the data. 3 is the best and
then it goes 3,2,1,0,A,B,and Z (the worst).
