Radio Frequency Interference

Geostationary Direct-Broadcast Services (DBS) Satellites
with significant RFI potential

Ocean reflected RFI is arguably the fastest growing source of errors in passive microwave observations. This work-in-progress catalogs Geostationary sources with significant RFI potential via Direct-broadcast Services (DBS). RFI may also result from Fixed-Satellite Services (FSS) aboard the same or similar constellation of satellites.
