Low Earth Orbit Constellations Could Pose Interference Risk to GEO Satellites

A proposed wave of low Earth orbit communications satellite constellations could become an interference hazard for satellites in geostationary orbit even if those new systems comply with existing rules, some satellite operators fear. Rules enacted by the International Telecommunication Union (ITU) in 2000, during the previous wave of proposed nongeostationary orbit (NGSO) satellite systems, gives frequency priority to satellites in geostationary orbit. NGSO systems must take measures, such as reducing their power output, to avoid interfering with geostationary satellites. More
