Recap from Mike's
previous posting regarding glhemaokpa margin of error:
"our 2 gps
receivers were not fully synchronized &
actually disagreed in the end by a couple
hundred feet i believe
tho i was trusting & going with bills more
than toms
since tom couldnt even say which nad he was
using
& was probably using "
I believe that
Cpt. Tom was using NAD27 as I was. His older Magellan handheld GPS
correlated within .02 nautical miles of my Garmin handheld unit. Given
that one nautical mile = 6,076 feet (about 1,852 meters), this would translate
to 121.52 feet (assuming that the ".02" is a precise number, which it is
not.) Obviously, this also doesn't take into account the "standard" GPS
margin of error (with Selective Availability turned off). Anyway, we were
close...and could indeed be at the exact spot.
