cannot find gps signal when using external Leo Bodnar GPSDO

[robertcluo]

Hi,

I am trying to use Leo Bodnar GPSDO as the external clock reference. However, I connect the signal into Reference IN and set it as GPS. However, I cannot see the GPS signal. Is there any specific setting for getting the gpsdo work?

Thanks

I think you have to place the GPS antenna near window. It works for me.

Hi @robertcluo, the Leo Bodnar requires a GPS lock, you will need to put the antenna next to a window, or somewhere with a clear view of the sky. It can take a couple of seconds for the lock to be acquired, the LED will stop blinking once it has the lock.

If you continue having issues I suggest you consult the documentation or reach out to Leo Bodnar directly.

Hi,
"clock_source=gpsdo" is reserved for the internal USRP GPS receiver. With the LEO Bodnar please use "clock_source=external"
