To create a GNSS contact for a rover Internet data link

When creating a GNSS contact for an RTK Internet data link, the Edit GNSS contact screen provides the following tabs:

  • Use the Network connection tab to select how you want to connect to the Internet.

  • Use the Corrections tab to select where you want to obtain RTK corrections from and to configure connection settings for the selected correction source.

  1. Tap and select Settings / Connections. Select the GNSS contacts tab.
  2. Tap New. The Edit GNSS contact screen appears.
  3. Enter the GNSS contact name.
  4. Set the Contact type to Internet rover.

  5. Configure the Network connection settings for the GNSS contact as required. See To configure how to connect to the Internet below.

  6. Configure the Corrections settings for the GNSS contact as required. See To configure correction settings below

  7. Tap Store.

Use the Network connection tab in the Edit GNSS contact screen to select how you want to connect to the Internet.

If the controller is an Android device, the only network connection option is to use the SIM card in the controller. The connection named Controller Internet is selected by default in the Network connection field.

When you connect to the Internet using the controller, the Controller Internet connection is available for other functions during the RTK survey, not just receiving RTK data. Other functions include downloading projects and jobs or sending email.

When using a Controller Internet connection, you can connect the controller to the receiver using Bluetooth or a serial cable.

To configure the network connection:

  1. In the Network connection field:

    1. Tap to open the Network connection screen and select the connection named Controller Internet.

    2. If you have not yet configured the Controller Internet connection, tap Configure in the Network connection screen to open the operating system connection settings screen and set up the connection.

    3. In the Network connection screen tap Accept to return to the Edit GNSS contact screen.

  2. Tap Store.

Trimble receivers with an internal modem running firmware released after 2017 can use a Receiver Internet connection.

When you connect to the Internet using the receiver, the Receiver Internet connection can only be used for receiving RTK data. You cannot use the Receiver Internet connection for other functions, such as downloading projects and jobs or sending email.

When using a Receiver Internet connection, you must connect the controller to the receiver using Bluetooth.

To configure the network connection:

  1. In the Network connection field, tap to open the Network connection screen and select the connection named Receiver Internet. Tap Accept.

    In most cases, you will not need to edit the Receiver Internet connection settings.

  2. If the SIM card in the receiver has a PIN, enter the PIN in the Modem pin field.
  3. Tap Store.

If you try the connection and it does not work, further configuration may be required:

  1. In the Network connection field, tap to open the Network connection screen.

  2. Select the connection named Receiver Internet and tap Edit.

  3. In the APN field, tap to choose the method for selecting the Access Point Name (APN) for the Internet service provider. This is the service provider that provided the SIM card in the receiver:

    • Choose SIM default to use the APN profile directly from the SIM card in the receiver.

    • Choose Select Access Point Name (APN) to select your Location and your Provider and plan from the APN wizard in Trimble Access. Tap Accept.

    • Choose Load from modem to connect to the modem and load and store the APN information from the modem to the GNSS contact. The settings stored in the GNSS contact will be used whenever you connect using the GNSS contact.

      The Load from modem option is available only if the receiver has firmware version 5.50 or later installed.

  4. Enter the Cellular username and Cellular password. By default these fields are both set to guest.
  5. Tap Accept.
  6. In the Network connection screen, tap Accept.
  7. Tap Store.

If you have another device such as an older receiver or a mobile phone that supports the Bluetooth DUN service, you can connect the controller to the Internet through that device. You can also connect the controller to the Internet through a separate smartphone.

The Internet connection is available for other functions during the RTK survey, not just receiving RTK data. Other functions include downloading projects and jobs or sending email.

To connect to the Internet through a receiver or a mobile phone that is not a smartphone:

  • The modem in the device must support the Bluetooth DUN service.

  • The receiver must be an older Trimble receiver, such as the R10-1 or R8s.

If your receiver does not support Bluetooth DUN and you want to be able to use the Internet on the controller, you must use a Controller Internet connection.

To connect the controller to the Internet using:

Use the Corrections tab in the Edit GNSS contact screen to select where you want to obtain RTK corrections from and to configure connection settings for the selected correction source.

  1. Set the Use RTX (Internet) switch to Yes.
  2. In the Mountpoint name field, select the mountpoint appropriate for your RTX subscription and region. The RTXIP mountpoint is for global RTX corrections, while others are particular to specific network coverage areas.
  3. If required, set the Use proxy server switch to Yes and then enter the proxy server address in the Proxy server field and enter the Proxy server port.
  4. Tap Store.
  1. Set the Use RTX (Internet) switch to No.
  2. Set the Use NTRIP switch to Yes.
  3. To force the Trimble Access software to always use NTRIP version 1.0, select the Use NTRIP v1.0 check box.
  4. If the NTRIP server:
    • uses a proxy server, set the Use proxy server switch to Yes and then enter the proxy server address in the Proxy server field and enter the Proxy server port.
    • does not use a proxy server, set the Use proxy server switch to No.

  5. To connect to a mountpoint on starting a survey without being prompted for the mountpoint name, set the Connect directly to Mountpoint switch to Yes and then enter the Mountpoint name.

    If a mountpoint name is not specified, the system will prompt you when you start a survey. Your selection will then be stored in GNSS contacts. If the specified mountpoint cannot be accessed when you start the survey, a list with available mountpoints appears.

  6. If a user name and password are required to use NTRIP server, enter the details in the NTRIP username and NTRIP password fields.

  7. In the IP Address and IP port fields, enter the information for the NTRIP server that were sent to you from the data provider.

  8. If the rover must supply identification information through regular NMEA messages to the base data server, select the Send user identity info check box. At the start of the survey, the software asks you to enter this information.
  9. Tap Store.

For more information, see NTRIP server settings.

  1. Set the Use RTX (Internet) switch to No.
  2. Set the Use NTRIP switch to No.

  3. In the IP Address and IP port fields, enter the information for the broadcast server that were sent to you from the data provider.

  4. If the rover must supply identification information through regular NMEA messages to the base data server, select the Send user identity info check box. At the start of the survey, the software asks you to enter this information.
  5. Tap Store.
  1. Set the Use RTX (Internet) switch to No.
  2. Set the Use NTRIP switch to No.

  3. In the IP Address and IP port fields, enter the information displayed in the IP Settings of this base field in the Base screen displayed on the controller at the base.

    If the IP address of the base controller appears to be invalid, Trimble recommends that you perform a soft reset of the device before you connect to the Internet and start the base.

  4. If the rover must supply identification information through regular NMEA messages to the base data server, select the Send user identity info check box. At the start of the survey, the software asks you to enter this information.
