Every GPS implementation is different.
It may be the case that higher SNR is required for timing receivers compared to
position receivers.

Sure. Generally I wouldn't expect GPS to work in a building. Though,
since we have at least 3 different systems (phone, RPi /w GPS-shield,
LTE eNodeB) that work there, I assumed that the GPSDO would do so as well.

Thanks for your hints. The antennae and devices are indoors. Is there a
difference if the device receives a signal and locking onto that signal?
e.g. the devices determines the signal too distorted to lock?

When I first started using UHD 4.0 with the N310 (this past summer), I
noticed what I thought was a degradation in the device's ability to
lock. I was comparing one N310 running UHD 3.15 to another running UHD
4.0. Both systems were located a few feet apart from each other with
the same model ante
Are the antennae situated outdoors?
It can take almost an hour to achieve lock from a cold start.

Each USRP has its own GPS antenna. One of those you buy at ettus.com as
a recommended accessory.

How are you delivering the GPS antenna signal to the USRPs? Via a splitter?
Does that splitter provide DC pass-through?

Just a quick follow-up. The B210 finally got a GPS lock. (I had to wait
for ~2h). Though, all N310s still don't.

My phone can see ~7 Satellites. We have a RPi with a GPS module that
locks to GPS in the same hall. We switched antennas but still, we can't
sync any of the USRPs to GPS
