Base With Internal Radio Transmitter
Script
In the example below, it is assumed that the receiver will
generate differential data in RCTM V3.0 format. You may
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).
$PASHS,ANT, 1.45 , 0.0921 , -0.0516
$PASHR,ACK*3D
Enter the coordinates of the base:
$PASHS,POS, 4717.93777 , N ,
130.541864 , W , 87.007
$PASHR,ACK*3D
Set the type of the radio transmitter and
the serial port to which it is connected: $PASHS,RDP,TYP, A ,PDL
$PASHR,ACK*3D
Set the baud rate of the port connected to
the radio. The recommended value is
38400 Bd.
$PASHS,PRT, A , 7
$PASHR,ACK*3D
If port A is used for the connection to the
transmitter, select the RS232 mode for
this port.
$PASHS,MDP,A,232
$PASHR,ACK*3D
If port B or F is used for the connection to
the transmitter, enable the extended com-
munication port:
$PASHS,ECP, ON
$PASHR,ACK*3D
Set the radio parameters (channel, proto-
col, air link speed) $PASHS,RDP,PAR, A ,PDL, 3 ,, 0 , 9600
$PASHR,ACK*3D
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
