No earth-based observation of the planets can disprove the Tychonian model (planets orbit sun, which orbits the earth). It takes very fine stellar observations, which couldn't be done in the 17th century.
Would a space based observation do it? Where would it have to be from, and what would be the differences?
Edit: I'd like answers that ignore stellar observations and only look at planets or the Sun- something like: "From the surface of Mars the positions of the planets show the model is incorrect."
