or missed the landing site. That fact is, you can really tell the exact position of a particular SV in any orbit. As for geostationary satellite, the movement is a 3-bodies problem, where there isn't a analytical solution. For more complicated cases, it involves solving multibody problem. In reality, nothing is so easy as it seems.
