1.128 PDOPLIMIT (ASCII)
SF-3050 Sapphire SF-3040
This command is used to set the maximum position dilution of precision (PDOP) allowed for a
valid navigation solution. If the satellites available for navigation have a geometry that results in
a PDOP value that exceeds this limit, the receiver will report that a navigation solution is not
available.
Command: [PDOPLIMIT] pdop
Parameter Definition
pdop PDOP limit (float, dimensionless) (2.0 to 100.0)
Default: 10.0
Example: [PDOPLIMIT] 10
Sets the PDOP limit to 10

When the PDOP reaches higher values, large errors can occur in the navigation
solution. If the PDOP limit is set too low, availability of the navigation solution may
decrease.
