The study has already been successful in picking up signals from FM stations in Perth and Geraldton reflected back to Earth by the international space station as it passed over Western Australia approximately 500 Km above the Earth’s surface. Team leader Professor Steven Tingay said "We have shown that we can detect approximately 10 pieces of space junk simultaneously. Over time this means we are in a position to monitor a significant fraction of the junk orbiting Earth".
