Configuration
Likewise, when you select Loran C, you can set the
Chain
yourself
(
Man
), or let the receiver calculate the chain for you (
Auto
, default).
Alarm For High HDOP:
This allows the receiver to create an alarm for HDOP values which
rise above a number that you determine. This indicates that posi-
tion accuracy is becoming bad, due to poor satellite geometry rela-
tive to your position and/or the number of satellites currently un-
der track. You may want to set the alarm to
Yes
if position accuracy
is critical to you. Otherwise this alarm is normally set to
No
.
HDOP Alarm Limit:
Sets the HDOP value which will cause the alarm to sound. The
default value is 4. The valid range is from 1.0 to 9.9. The higher your
HDOP value, the more error you will have in your position fix. Refer
to the
GPS1 Current Satellite Status
section of this manual for
more information about the HDOP value.
Alarm If No Update:
This setting causes an alarm when you stop calculating a position
fix for a few seconds when set to
Yes
(default). A setting of
No
disables the alarm when position fix can not be obtained.
