The value of HDOP (horizontal dilution of precision)
expresses “the quality” of the satellite geometry in rela-
tion to 2D positioning and a fixed antenna altitude.
PDOP (position dilution of precision) is equivalent to
3D positioning. The values will typically stay between
1.3 and 8. The lower the value the higher the “quality”.
A poor geometry might produce a value of more than
20.
If the preset DOP limit is exceeded (indicated by * in
the position display) it will cause the position updating
to stop until it once again is within the limit.
The DOP limit can be changed manually, but should
not be set to higher than 8 (factory set-up), as this may
result in poor accuracy - false position.
