Description
1
Ideal
This is the highest possible confidence level to be used for
applications demanding the highest possible precision at all
times.
1-2
Excellent
At this confidence level, positional measurements are considered
accurate enough to meet all but the most sensitive applications.
2-5
Good
Represents a level that marks the minimum appropriate for
making business decisions. Positional measurements could be
used to make reliable in-route navigation suggestions to the user.
5-10
Moderate
Positional measurements could be used for calculations, but the
fix quality could still be improved. A more open view of the sky is
recommended.
10-20
Fair
Represents a low confidence level. Positional measurements
should be discarded or used only to indicate a very rough
estimate of the current location.
>20
Poor
At this level, measurements are inaccurate by as much as 300
meters with a 6 meter accurate device (50 DOP × 6 meters) and
should be discarded.
