European satellite 'blinded' by radio interference - Oct 2010
The European Space Agency (ESA) said on Wednesday that it had launched a behind-the-scenes campaign to shut down illicit radio and TV transmissions interfering with a major climate satellite.
The 315-million-euro (434-million-dollar) Soil Moisture and Ocean Salinity (SMOS) probe "has been bugged by patches of interference from radar, TV and radio transmissions in what should be a protected band," ESA complained.

Analysis: Sorting out the LightSquared GPS interference mess
“It was clear there were very different interpretations of the data from the GPS group and from LightSquared,” Spirent’s Butler said. “What it came down to was the definition of harmful interference.

Finding the Harm in "Harmful Interference" : CommLawBlog - Mitch Lazarus
"Periodically one or another spectrum management body calls for the FCC to promulgate a more objective definition of harmful interference. But that would be ill-advised. We will do much better to continue with a vague formulation that leaves the FCC the flexibility it needs to reach the right result in case-by-case decisions."
