PDOP Operating Values

PDOP operating values should remain BELOW 3.5
DURING ALL AUTOTRAC OPERATIONS, especially RTK
high precision operations. As the value of PDOP rises
above 3.5, position accuracy will be compromised.
As a rule, when the GPS receiver is warming up from
being in a powered off state and gathering satellite signals
high PDOP values (4 to 20+) will be experienced for
upwards of 15 minutes (under normal conditions).
It is important to monitor PDOP along with GPS signal
quality while performing eld operations.
