Subject: GPS antennas... debugging 

Visual inspection of rooftop GPS antennae:

The 2 GPS antennas are located on the north west corner of CES roof. Their condition looks well weathered. I'd be surprised if they work.

The BNC connector of the 1553 head is inside of the conduit so it is more likely to have a better connection than the other one.

I have not had a chance to look into the "GPS Time Server" unit.
