I've been thinking about #GPS jamming and radio waves. Could jamming activity bounce off the ionosphere and impact other areas?

I somewhat expect that the frequencies in use are designed to go through the ionosphere, and so "no," but also finding bits about scintillation causing accidental errors.

Eg, https://novatel.com/tech-talk/ionospheric-scintillation/redundancy-and-resiliency-against-ionospheric-scintillation

and https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2024SW004217 shows 3d errors of up to 30 meters
