No, it doesn't. The Earth changes it's position relative to the Sun literally every second. It is the static tilt of the Earth's own axis that determines how far above the horizon the Sun gets at local noon for your location.

In terms of our lifetimes it's static. I have a german equatorial mounting that contains a polar axis telescope for obtaining precise polar alignment. The reticule in this scope is finely graduated to adjust on an annual basis, for the precession of the tilt of the earth.

Nice. I've got three Cave Astrola's newts on similar mountings. My favorite though is a six inch f/15 Cave Astrola refractor. Only three known to exist. It's great for planetary and double star work from my city location which is good because it's too long and heavy to transport to a dark sky location.
