GPS Antenna aiming
I've been using this site to see when Galileo sats will appear in my antennas limited field-of-view: https://www.n2yo.com/whats-up/?c=22You can see from the orbital tracks why the shadow hole exists if you're located close enough to the poles. From the north pole all GPS sats would appear biased toward the south.Here's a great animation of various satellite orbital heights: https://upload.wikimedia.org/wikipedia/commons/b/b4/Comparison_satellite_navigation_orbits.svgDue to QZSS I learned there is a difference between the terms geosynchronous and geostationary. 3 of the 4 QZSS sats trace the same figure-8 pattern on the Earth because they are geosynchronous (and have a high inclination). QZS-3 is truly geostationary (appears at a single point on the Earth) like the majority of the communications satellites.

GPS antenna alternatives
Yes, I've noticed this "too perfect" shadow on other Kiwis. But I'll let you tell the story.. -

That's not a bad idea. And it could be done in a way that doesn't leak the Kiwis precise location (i.e. with any greater resolution than the current maps) -
QZSS Support [GPS, added in v1.170]
Well, the alert flag is on, but QZS-3/PRN199 seems to be up and decoding subframes! And the az/el is right where it's supposed to be. Also seen in Shenzhen and Adelaide, Australia.
