Hi, can the module disable a specific GNSS frequency or signal?
Hello, Yes, absolutely. The module allows you to easily enable or disable specific GNSS signals using commands.
To disable a specific signal, you can use the command: set signal xxx off
To enable the signal again, use: set signal xxx on
For example, if you want to disable or enable the GPS L2C signal, you would send: set signal l2c off set signal l2c on
Simply replace xxx with the corresponding signal name depending on the frequency you want to control.
That's very clear, thank you. What if I want to disable an entire constellation, like GLONASS or Galileo, instead of just a single frequency?
Yes certainly. You can control entire satellite constellations just as easily.
If you want to disable an entire system rather than a specific frequency, you can use the LOCKOUTSYSTEM command. For example, to disable all BeiDou-2 satellites, you would send: LOCKOUTSYSTEM BD2
To enable the system again, you can use the corresponding unlock command, such as: UNLOCKOUTSYSTEM BD2
This feature is particularly useful if you are testing the receiver's performance under specific conditions, or if you want to isolate a specific constellation. More details about all the supported system names can be found in our module reference manual.
Got it. If I turn off a specific signal or constellation, will the module remember this setting after I reboot it?
Hello, by default, these changes are only applied to the current session. If you restart the module, it will revert to its default settings (tracking all available signals).
If you want the module to remember your new configuration after a power cycle, you need to save the settings to its non-volatile memory. You can do this by sending the following command: saveconfig
Once you send this, your custom signal tracking configuration will be preserved. If you ever want to discard your custom settings and restore the module to its factory default tracking state, you can send the freset command.
If you need help configuring anything else, feel free to ask!
