  5. List of satellites in geosynchronous orbit - Wikipedia

    en.wikipedia.org/wiki/List_of_satellites_in...

    This is a list of satellites in geosynchronous orbit (GSO). These satellites are commonly used for communication purposes, such as radio and television networks, back-haul, and direct broadcast. Traditional global navigation systems do not use geosynchronous satellites, but some SBAS navigation satellites do.
