Note that these steps are only applicable for LD6 versions 8 or 50. If required see How do I tell which version of LD6 I have?
In order to remove satellites from a receiver a connection must be established to the GNSS card. In order to connect to the LD6 GNSS card Septentrio RxControl software must establish a connection to the GNSS config port. This can be done using serial connection to an LD6 port configured as ‘GNSS Config’ or via an IP connection connecting to the LD6 unit on port 9013. A serial config will need to be opened for GNSS config in order to connect via IP port as otherwise the port is closed. This can be done by going to Settings > IO and selecting a port which is not in use and configuring it as GNSS Config (a port may already be configured as such- if so omit this step).
In order to enable connection to an IP port in RxControl go to File > Preferences and tick the box labelled Show port number for TCP/IP connections shown below:
Once connection has been established to the GNSS card open the sky plot window by selecting the button highlighted below:
Selecting this will open the following window which will show the satellites that are currently being tracked:
Next open the tracking windows by selecting Navigation > Advanced User Settings > Tracking… as shown below:
This will open the following page which will allow you to deselect satellites that are currently being tracked:
Uncheck the boxes of the satellites that you do not wish to track and select Apply. This will remove them from use in the receiver.
If you wish for the settings to persist through the GNSS card being powered down or rebooted you will need to save the settings before exiting RxControl. To do this go to File > Copy Configuration and select Current for copy from and Boot for copy to and click Apply.
Once tests are complete return to the tracking menu and ensure that the satellites are re-enabled for tracking. Once again if you want settings to persist through reboots and power loss the settings will need to be saved as described above.
