1. ### Pinning a gyroscope will resist change in orientation

Thanks for the info guys. :-)
2. ### Pinning a gyroscope will resist change in orientation

Is that simply because real world is not a "perfect world" situation?
3. ### Pinning a gyroscope will resist change in orientation

Ah, I see how that works. Though if it isn't aligned with the Earth's axis it would not work well as a compass?
4. ### Pinning a gyroscope will resist change in orientation

So assuming the rotor is spinning forever regardless of where I take it in the universe it will always point in the exact direction that I started spinning it at? If that is the case then how do things which use gyroscopes to determine direction compensate for the earth's spin and orbit?
5. ### Pinning a gyroscope will resist change in orientation

I know when spinning a gyroscope will resist change in orientation so that the rotor is still pointing in the same direction. But, is that direction with respect to earth's center of gravity or is it an "absolute direction". So, if I point a gyroscope upwards and spin the rotor and I go...
6. ### My misconception?
