In ISS planning, NASA examined options including returning the station to Earth via shuttle missions (deemed too expensive, as the station(USOS) is not designed for disassembly and this would require at least 27 shuttle missions), natural orbital decay with random reentry similar to Skylab, boosting the station to a higher altitude (which would simply delay reentry) and a controlled targeted de-orbit to a remote ocean area. The technical feasibility of a controlled targeted deorbit into a remote

Sean O'Connor says that it only covers the region between and above the Earth, providing information on satellites in geostationary orbit. Something in the FAS sourcebook says that the site has two components. This says that equipment with the GRAU index 60Zh6 covers craft in higher orbits and 59Zh6 and 57Zh6 covers craft in lower orbit.. The whole facility is given the name Object 2327S.
