Researchers from the Universidad Carlos III de Madrid (UC3M), Polytechnic University of Milan and the company GMV have developed a new methodology for detecting and estimating satellite maneuvers that improves the operation of the systems currently in use. This development, which is already being tested in operational environments, may help reduce the problem of space debris.
The number of satellites and fragments of space debris in Earth orbit currently amounts to around 30,000, according to the European Space Agency (ESA) and NASA catalogs, although researchers in this field estimate the real number to be around 100,000.
