I've done the 48 hour survey, but my signal plot shows a big circular
shaped mouse bite on the north side. I'm showing no signal up through 70
degrees at north, 30 degrees from NE around to NW. How badly will this
impact me?
The 24 GPS satellites are in orbits that never pass over the poles.
I think they are about 60 degree inclinations. By your description
you must be in the northern hemisphere. If you can, set up your
antenna so it can see to the south and don't worry if the view of the
north is blocked because as you found there is nothing to see there.

Not caring about north visibility of satellites from the antenna is
ignorant. The satellites on either side of the "hole" will help a lot with
the geometry of you solution.
I live in the southern part of Sweden, I still see satellites tracked
directly north of me albeit a rather low elevation.
I agree with Björn here. The better north-view you can get, the more
north-bound orbits can be used for improved symmetry.
I've been very surprised about the coverage that my current antenna
position, so using the detected amplitude plot of lady heather.
