Yes, I've seen this. On installations in the past, when we were putting up
dual GPS systems, we always put them at least 10 metres apart. What is
actually best practice, is to put one at one end of building and the other
one at the other end.

It's possible that LO leakage from one is jamming the other. When doing
mobile GPS receiver testing at work with a single antenna feeding multiple
receivers through a splitter, we sometimes had to insert attenuators in each
receiver's antenna feed to keep them from jamming each other.
