RTK internet data link
Use an internet data link if you are obtaining GNSS corrections for your RTK survey over the internet. RTK data is transferred by connecting to a server using an IP address.
Configuring the RTK survey style for an internet data link has two parts:
-
GNSS corrections source: where the Trimble Access software will obtain RTK data from
-
GNSS internet source: how the GNSS rover or the GNSS base will connect to the internet to obtain or transmit RTK data
At the rover
For the rover, the GNSS correction source is where the Trimble Access software will obtain RTK data from.
Depending on the services you have access to and your equipment setup, the options are:
-
Trimble CenterPoint RTX correction service
-
an NTRIP server
-
a broadcast server
-
a controller connected to the base receiver (if you have a controller that you can leave at the base)
For more information, see To configure a rover internet data link.
At the base
For the base, the GNSS correction source is where the Trimble Access software will upload RTK data to.
Depending on your equipment setup, the options are:
-
an NTRIP server
-
a broadcast server
For more information, see To configure a base internet data link
At the rover
For the rover, the most common GNSS internet source options are:
-
Controller internet: use the SIM card in the controller or the controller's connection to a Wi-Fi network to connect to the internet.
-
Receiver internet - modem: use the SIM card in the receiver to connect to the internet. The receiver must be a Trimble receiver with an internal modem.
-
Receiver internet - WiFi: connect the receiver over Wi-Fi network to another device that is connected to the internet, such as a cell phone or MiFi device.
When the GNSS internet source is:
-
Controller internet, you can use the internet for other functions during the RTK survey, not just receiving RTK data. Other functions include downloading projects and jobs or sending email.
-
Receiver internet - modem or Receiver internet - WiFi, you can use the internet only to receive RTK data. You cannot use the internet for other functions.
Less commonly, you might connect to the internet using these GNSS internet source options:
-
Receiver modem: use the modem in an older Trimble receiver such as the R10-1 or R8s to connect to the internet.
-
Add your own source, such as a smartphone connected to the controller or a mobile phone that supports the Bluetooth DUN service.
For more information, see To configure a rover internet data link.
At the base
Typically, you will need to disconnect the controller from the base receiver after survey setup so that you can use it at the rover.
For the base, the most common GNSS internet source options are:
-
Receiver internet - modem: use the SIM card in the receiver to connect to the internet. The receiver must be a Trimble receiver with an internal modem.
-
Receiver internet - WiFi: connect the receiver over Wi-Fi network to another device that is connected to the internet, such as a cell phone or MiFi device.
If you can leave additional equipment connected to the base receiver, you could select the following GNSS internet source options:
-
Controller internet: use the SIM card in the controller or the controller's connection to a Wi-Fi network to connect to the internet. This option is only suitable if you can leave the controller connected to the base receiver.
-
Receiver internet - cable: connect the receiver to an external device such as a laptop using a USB or ethernet cable.
Less commonly, you might connect to the internet using these GNSS internet source options:
-
Receiver modem: use the modem in an older Trimble receiver to connect to the internet.
-
Add your own source, such as a smartphone connected to the controller or a mobile phone that supports the Bluetooth DUN service.
