We have this at a couple sites each year. Usually, I can mount the GPS
antenna in a different place and solve the issue. Whats interesting is,
I don't see this issue with the SyncBoxes, only CMM Micro. And I have
both at the same towers affected.

We have a SyncInjector mounted on the south side of a concrete
building. The building is thick concrete ( > 12"), and extends up
above the location of the GPS antenna 30 or 40 feet. The building is
also a shallow "V" shape with the GPS antenna at inside base of the V.
So the GPS antenna gets about 170° view of the sky to the south.
It goes through a periodic cycle of visibility, but it's not the same
time every night, or even every day.

But the question is, why at the same time every day? Especially
since the gps satellites don't orbit on a 24 hour period... that's
what has me troubled with my customer.

Exposure to the north or south should not make a significant
difference. GPS satellites, excepting the WAAS satellites, are
not in geostationary orbits. They are (mostly?) in medium earth
orbit of around 12,000 miles.
I think it may be more of how much of the sky they can see.

how much exposure to the northern hemisphere does it have?
If I remember those antennas are fairly small

I have an epmp that has GPS problems and goes into the hold
timer for a few minutes every single night for the last many
months (maybe even a year).
Didn't think much of it until I noticed all of the times being
right around midnight, give or take...
WTF? Any ideas what's causing it?
