Correct, aprs.fi is intentionally filtering out all satellite objects. A
bunch of different people are, at times, transmitting these, sometimes
duplicates for the same satellites. It doesn't make sense to store this
data on aprs.fi, as there are more useful sites and software for satellite
tracking. They can display future positions, too, and visibility plots.
Besides, the positions of satellites are predictable using the kepler
elements, so it doesn't make much sense to use a lot of bandwidth or disk
space to store the actual calculated coordinates.
