Your GPS is correct!
---------
>dist = 6366.7*Arccos(sin(lata)*sin(latb)+cos(lata)*cos(latb)*cos(lonb-lona))

??????
The equation above is incorrrect.
--------
The above equation should read for the Great Circle Distance between Points
A and B
located as;
A at location (Lat_A, Lon_A) and B at (Lat_B, Lon_B)
Distance A to B = 60*ArcCos[Sin(Lat_A)*Sin(Lat_B) + Cos(Lat_A)*Cos(Lat_B) *
Cos(Lon_A -Lon_B)]
The result is in nautical miles.
