,OAD STATUS DISPLAY
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.

to acknowledge a beeping alarm.
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.
