Commands

TST:Output RTK Latency

$PASHS,TST,d

Enable/Disable the output of the RTK (fast CPD) latency as decimal part of the age of

correction in the GGA message. There is no query to check this setting since it is

visible in the GGA message (age of correction is an integer number when disabled).

This setting will revert back to default at power on unless saved in battery-backed

memory through the $PASHS,SAV,Y command (issued after setting the desired

mode).

Example: Enable Fast CPD latency output

$PASHS,TST,220 <enter>

UNH: Unhealthy SVs

$PASHS,UNH,c

Include unhealthy SVs for position computation, where c is Y (yes) or N (no,

default)

Example: Include unhealthy SVs in position computation

$PASHS,UNH,Y <enter>

USE: Use Satellites

$PASHS,USE,d,c

Selects satellites to track or not track, where d is the PRN number of the satellite

(range from 1 to 32) or ALL for all satellites and c is Y (enable) or N (disable).

Example: Do not track satellite 14

$PASHS,USE,14,N <enter>

VDP: VDOP Mask

$PASHS,VDP,d

Sets the value of VDOP mask, where d is between 0 and 99. The default is 4.
