The value of HDOP (horizontal dilution of pre-
cision) expresses “the quality” of the satellite
geometry in relation 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.
