Hi,
I am using the /usr/local/lib/uhd/utils/query_gpsdo_sensors to get

**************************************Helpful Notes on Clock/PPS
Selection**************************************
As you can see, the default 10 MHz Reference and 1 PPS signals are now
from the GPSDO.
If you would like to use the internal reference(TCXO) in other
applications, you must configure that explicitly.

I do plug the GPSDO to the board, and I plug the 5V active GPS antenna
in the `GPS ANT` connector at the rear panel. But I am not sure why. I
just want to get the location information. (btw, is it because I am in
the indoor area?)
Thanks,

I would re-check the GPSDO installation. You may have bent one of the
pins when you installed it.
Also, it won't be able to get a "fix" unless the antenna can "see" the
sky. Most buildings are not that transparent at 1575MHz.
