Hello，Safran engineers, I have a question I would like to confirm with you.
I am trying to implement RTK using a USRP 2954R, where the USRP generates the RF signal, and the other instance is NoneRT, and the RTCM plugin is enabled. After I set up the synchronization, the following error appears: “Can not use GpSDO as reference 10MHz clock with the current configuration.Please, select external 10MHz reference clock.”
I checked the manual and the only relevant description is in the PPS IN Delay section, and it seems that the default is to use an external reference as long as the multi-instance function is enabled, even if I only use one hardware.
I want to know if I understand correctly, if I want to use NoneRT+USRP to implement RTK, do I also need an external reference?
Our experts have a few questions, but it seems (at first glance) that the problem seems to be that the radio is not being detected.
Have you tried using the radio with a simple (non-RTK) scenario?
Can you share the parameters you are using in the Edit>Preferences window so we can see how the card’s timing is managed?
Finally, can you let us know what version of Skydel you are running? GPSDO functionality has changed a little in the last few versions and it would be helpful to know which you are running.
Thanks very much and we look forward to your answers.
