Query Status of Currently Locked Satellites
$PASHQ,STA
This command asks for the status of currently locked satellites. The structure is
$PASHQ,STA or
$PASHQ,STA,x
where x is the port to output the response. If no port is specified, the response is
output from the port that received the request.
A typical response is shown below
TIME 17:16:59 UTC
LOCKED 29 18 02 19 07 28 27 31 16
CA S/N 25 60 79 85 20 21 92 55 46
P1 S/N 99 61 70 34 38 99 25 41 29
P2 S/N 99 61 70 34 38 99 25 41 29
Query SV Mode Selection
$PASHQ,SVM
This command asks for the current SV mode selection. The structure is
$PASHQ,SVM.
$PASHR,SVM
The response message is in the form
$PASHR,SVM,ss,m where the fields are as described in Table 4.26.
Use Unheathy SVs
$PASHS,UNH
This command lets you use unhealthy SVs for position computation.
The structure is $PASHS,UNH,x where x is Y (yes) or N (no).
Example: Include unhealthy SVs
