CHAPTER 4. CONFIGURING THE ALTUS NR3 AS A ROVER
4.2.3 Connecting via Data Call
The setup described in this section is represented schematically in Figure 5-3. Differential
corrections from the base station to the rover are transferred over a GSM cellular modem call
without the need for an Internet connection (also known a Circuit Switch Data connection or
CSD). In the example shown, the rover receiver calls the base station receiver on the number
0474 90 86 52
.
Step 1: Check the receiver is in Rover mode
Section 4.1 shows how you can check that the Altus NR3 is set to work as a rover.
Step 2: Configure the connection to the base station
From the ‘Communication’ menu select ‘Cellular’, where you can con
fi
gure the cellular
modem of the rover receiver to make a data call to the base station receiver. The essential
settings are shown highlighted in Figure 4-7 with other settings being optional.
After clicking on the
‘
Ok
’
button, the rover receiver will automatically call the base station
receiver on the number in the
‘
Call number
’ fi
eld. If the connection is broken or the base
station fails to answer, the rover will continually try to call the base station.
