10.2.7 HDOP alarm
Fig. 86
"HDOP" is the parameter that depends on the position and number of satellites in space that affect the
positional precision of the system (longitude and latitude); the lower the value, the higher is the driving
precision.
The precision alarm is triggered when the value of HDOP measured by the GPS receiver is above the set
limit.
We recommend NOT to set values above 4.0.
