You can't do this on a long term scale with something that's below geostationary orbit, because random solar flares and solar phenomena cause expansion and contraction of the earth's atmosphere at unpredictable times. If you have a satellite in an orbit that is low enough to gradually degrade through atmospheric drag (even if it's a very high-LEO orbit or molniya orbit that won't reenter for an estimated 300 years), the exact time that it will re-enter can't be predicted with any confidence. At least not if you are talking about a very long time scale. Short-term (3, 5 or 7 year time scale) orbit degradation of things in LEO is predictable based on orbital height and known atmospheric density at a given altitude, but beyond that any re-entry predictions become much more fuzzy.
If you want to put something in orbit that will stay in a predictable location, you don't want it to re-enter at all, you want to put it in an orbit that is high enough to not be affected by atmospheric drag on a geologic time scale. Something slightly beyond geostationary will still be there in 200,000 years.
