CHAPTER 4. CONFIGURING THE ALTUS NR3 AS A ROVER
4.2.4 Connecting via an IP address using Mobile
Internet
You can con
fi
gure the rover receiver to accept differential corrections from an IP address.
In this case, the base station receiver, be it a Reference Network or another Altus NR3, is
sending corrections over IP. This section describes the rover settings for the Altus NR3. Please
review Section 5.2.2 for the con
fi
guration of the Altus NR3 as a base using an IP address.
The setup described in this section is represented schematically in Figure 4-8.
Figure 4-8:
Base-Rover con
fi
guration using GSM
Step 1: Configure your cellular connection
Make sure that the Cell modem of the Altus NR3 is connected to the internet as described in
Section 4.2.1.
Step 2: Configure the IPR connection
Setup an IPR (Receive) connection so the unit can accept the differential corrections via the
Cellular internet connection. On the
‘ Communication/IP Settings ’ menu, con fi gure and IPR
connection with the IP address either from the Reference Station or from the Altus NR3 (the
IP address assigned by the GSM or Cellular internet connection - See Figure 5-7) and select
the port number con
fi gured for the base station as shown in Figure 4-9.
Alternatively you can also use the Dynamic DNS feature (See Section 6.4) of the Altus NR3 in
which case you can use a dedicated URL instead of an IP address (e.g. nr3-123.dyndns.org).
In this case it is recommended to con
fi gure the Dynamic DNS service in the Altus NR3 base
station allowing the rover receiver to use a URL instead of an IP address in the IPR connection
settings described above.
