@sundogplanets I don't have a degree in astrophysics, but I'm trying to understand your point of view better regarding Starlink's impact (I'm a Starlink user in rural France with poor DSL alternative). You mentioned that it could get so bad that radio astronomers might not even be able to use quasars to calibrate GPS anymore.

From what I understand, quasars are used in techniques like Delta-DOR to correct for errors in spacecraft navigation, relying on the precise positions of these objects. But I'm curious—are you saying that the radio interference from Starlink satellites could eventually become so severe that it would make these kinds of calibrations unreliable?

If so, what specifically about Starlink's radio emissions makes this scenario a real possibility? Are there frequency overlaps or specific effects that would make this issue hard to mitigate with current technology?

I appreciate any insights, as I'm trying to responsibly wrap my head around how this interference could affect something as fundamental as GPS synchronization using quasars.
