Configure IBSS - Trimble Access – Ultimate Positioning Group

Internet Base Station Service (IBSS)

The Trimble IBSS service provides an easy way for you to stream RTK corrections over the internet from a base station to rover receivers. Once you have set up the GNSS receiver as a base station and chosen IBSS as your base data link, RTK corrections are automatically streamed to any rover that is also using IBSS in the same Trimble Connect project. No separate configuration for the corrections server is needed.

You can set up multiple IBSS streams in a project, one per base receiver. The base receiver can be in a permanent fixed position or it can be a temporary base that you set up each day. IBSS streams exist until you delete them, regardless of whether a base is broadcasting corrections. This allows you to use the same stream, day after day, even if you are shifting your base to different locations in the project.

As many rover receivers as required can use the RTK corrections provided by IBSS within the same Trimble Connect project.

NOTE -

To use IBSS in Trimble Access, the IBSS stream must be created in a project that resides in Trimble Connect. If your organization streams IBSS via Trimble Connected Community (TCC) or Works Manager, those IBSS streams are not available in Trimble Access.

Spectra Geospatial SP60, SP80, SP85 and SP90m GNSS receivers cannot be used as base receivers with IBSS.

Trimble Access must be under Software Maintenance.

To configure the survey style to use IBSS

For the rover:

Tap and select Settings / Survey styles. Select New.

Enter in Style name and Style type is GNSS.

Tap Rover data link.

Set the Type field to Internet connection.

Tap next to the GNSS correction source field to open the GNSS correction source tab of the Connections screen and then tap the IBSS GNSS correction source to select it.

To set security options for the connection, tap Edit.

By default, the connection uses Enhanced security and encrypts the data using Transport Layer Security (TLS) internet data encryption on port 2105. If your network firewall does not support TLS encryption, select Maximum compatibility. When Maximum compatibility is selected, unencrypted data is sent using port 2101. Tap Store.

Tap Accept.

When you select the IBSS GNSS correction source then the following settings are set automatically:

Controller internet is selected as the GNSS internet source. The software will connect to the internet using the controller's internet connection.

The Prompt for GNSS internet source setting is set to No.

Tap Accept to save your changes in the Rover data link screen.

Tap Store to save your changes to the survey style.

For the base:

Tap Base data link.

Set the Type field to Internet connection.

Tap next to the GNSS correction source field to open the GNSS correction source tab of the Connections screen and then tap the IBSS GNSS correction source to select it and then tap Accept.

To set security options for the connection, tap Edit.

Tap Accept.

To select the GNSS internet source (how the GNSS base will connect to the internet for GNSS corrections), tap to open the GNSS internet source screen and select the required GNSS internet source.

Typically, you will use Receiver internet - WiFi and these options do not usually required further configuration.

Tap Accept.

Tap Accept to save your changes in the Base data link screen.

Tap Store to save your changes to the survey style.

To configure the Wi‑Fi settings in a receiver that is Wi‑Fi enabled:

Connect to the receiver but do not start a survey.

Tap and select Instrument / Receiver settings and tap Wi‑Fi. The Receiver Wi-Fi configuration screen appears.

If the Wi-Fi softkey is not shown, make sure you have not started a survey.

Select the required tab:

- Select the Access point tab and select the Enabled check box to enable the receiver as an access point so that many clients can connect to it.

Access point mode also enables you to use the receiver as a mobile hotspot.

Select the Client tab and select the Enabled check box to enable the receiver to connect to an existing network.

Client mode enables you to connect to the internet and receive GNSS base data corrections during an RTK internet survey.

Some receiver models allow you to have both Access Point and Client mode enabled, or only one mode on, or both modes off. For receivers that support only one mode at a time, enabling one mode in the Receiver Wi-Fi configuration screen automatically disables the other mode. Using receiver Wi-Fi will shorten the run time of the receiver battery.
