Symmetricom 58532A antenna, just above the roof, with 8 feet of RG213.
Flat ( Florida) rural location with 360 degree view other than some trees. The
GPS Antenna plot from Z38xx has filled in pretty much 360 degrees down to 20
degrees solid and in most directions to down to 15 degrees elevation. The
exception of course is the polar abyss to the north. I am going to lower the
elevation angle for a while just to see if there is any difference
Looking at the link sent to me earlier
http://www.realhamradio.com/GPS_websites_list.htm . I am seeing the same phenomena
on most all oft the plots for the Z3801 around the world, So I assume that my unit
is :behaving normally" for a Z3801A ... Just cant explain why all of us see a
sporadic jumps in PPS error for an hour or two once or twice a day

Please describe your Antenna setup and location.
How much of the sky can it see, in which directions.
Which directions are blocked for direct line of sight, and must depend on
reflections from nearby buildings or objects?

And here is the question is the sudden jump in the pps deviation due to
ionospheric and the satellite constellation change? IS there anything I can do
to minimize it (or is it even necessary to worry/ wonder about) This behavior
has going on since the beginning so it is not likely related to events earlier
in the week. But that set me to wondering could I minimize it by say raising
the elevation mask? Are there satellites in the constellation that are
notorious for noise etc that could be excluded from the tracking list ...etc
etc
