Operation
Base Using Port A as Corrections Output
In the example below, it is assumed that the receiver will
generate differential data in RCTM V3.0 format. You may
replace RT3 with RT2 (RTCM2.3), ATOM, CMR or CMP
(CMR+) or DBEN.
See $PASHS,RTC,TYP, $PASHS,RNX,TYP or
$PASHS,CMR,TYP if you want to change the default
messages and periods.
Set the type of differential data that will be
generated by the receiver as well as the
port routing the data to the transmitter:
$PASHS,BAS,A, RT3
$PASHR,ACK*3D
Set the receiver to be a base transmitting
GPS data (+ GLONASS and/or SBAS
data):
$PASHS,CPD,MOD,BAS, 0
$PASHR,ACK*3D
Action Command
Action Command
Query the radio settings
(channel, protocol and air link
speed):
If a radio transmitter P/N 800986:
$PASHQ,RDP,PAR,A
$PASHR,RDP,PAR,A,MGL,,
3 ,,2,4800,,
447.1000,447.1000,12.5,430-450,*48
Query the channel table:
If a radio transmitter P/N 800986:
$PASHQ,RDP,CHT,A
$PASHR,RDP,CHT,MGL,
2 , 0 , 464.5000 ,0.0000, 1 ,
464.5500 ,0.0000*31
Action Command
Set the name of the antenna connected to
the receiver: $PASHS,ANP,OWN, ASH111661
$PASHR,ACK*3D
Set the antenna reduction mode to ON,
so that all coordinates refer to the ground
mark:
$PASHS,ANR,ON
$PASHR,ACK*3D
Set the antenna height (for example a
slant height of 1.45 meters was mea-
sured):
NOTE: When a slant height is entered,
you also need to enter the antenna radius
and the ARP-to-SHMP vertical offset
(negative if ARP is below SHMP).
