Geostar Radiodetermination Satellite Service (RDSS) measures the position of vehicles on the earth using geostationary satellites and time-difference ranging techniques. One of the RDSS frequency bands overlaps with a radio astronomy frequency allocation. The Federal Communications Commission (FCC) mandated a unique spacetime frequency sharing rule to minimize interference.
