load satellite 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 preset DOP limit is exceeded (indicated by * in the position dis-
play) 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 (default), as this may result in poor accuracy i.e. false
position.
Position update alarm - go to “Alarm” in the display and set it to
“ON” if you wish to be alerted when there is no position update.
