The value of HDOP
(horizontal dilution of precision)
expresses โthe qualityโ 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 โqualityโ. 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 higher than
8 (factory setup), as this may result in poor accuracy โ false position.
Position update alarm - go to โAlarmโ in the display and set it to โONโ
if you wish to be alerted when there is no position update.
