$PASHQ,SVP
The associated query command is $PASHQ,SVP,x where x is the optional output
port.
Example: Direct SVP query to port A:
$PASHQ,SVP,a<Enter>
$PASHR,SVP
The response message is in the form $PASHR,SVP,c1,c2....c56 where each c is
associated with the setting of one of the 56 PRN numbers.
SVS: Satellite Selection
$PASHS,SVS,c1,c2,c3........C56
Select satellites that the GG Surveyor attempts to acquire, where:
c= Y, satellite is used (default). x = N, satellite is not used.
U
p to 56 satellites may be selected. They are entered in order of PRN number, where numbers from
1 to 32 correspond to GPS satellites, and 33 to 56 to GLONASS satellites. If fewer than 56 are
specified the rest are left as they are. Only the characters Y and N are accepted.
Example: Use 1-9, 12, 13, 33-36, 39-40, 45-56 do not use 10, 11, 14-32, 37, 38, 41-44

SYS: Set Navigational System
$PASHS,SYS,s
Set navigational system to be used for positioning, where s is GPS, GLO, or MIX:
GPS - Only GPS is used
GLO - Only GLONASS is used
MIX - Both systems are used (default)
Example: Set the receiver to use GPS only
$PASHS,SYS,GPS<Enter>
TDP: Time Shift Dilution of Precision
$PASHS,TDP,d
Set GLONASS system time shift DOP mask, where d is 0 to 99. Default is 4. This is
analogous to the VDP command. The time shift is only computed when TDOP is less
