Interesting question. GPS jamming is a DoS attack that saturates the L-band (1.25 GHz) frequency. Jamming affects commercial vehicles, most likely civilian planes and ships. The military uses M-code, and it's unlikely that they are affected. There is speculation that Iran is using China's BeiDou satellite navigation system, which is resistant to US jamming.

@ai6yr Thought you would be interested in this app using SAR data to find GPS jamming

@ai6yr I've known Sean for a couple of decades. I was on the board of one of his many startups. He does fascinating work on all things spatial.

@ai6yr Fascinating post on detecting GPS jamming using Sentinel-1 synthetic aperture radar imagery

Can Sentinel-1 Detect GNSS Jamming? New Evidence from Temporal Baseline Analysis

We previously investigated whether Sentinel-1 C-band SAR (5.405 GHz) could detect radio frequency interference from GNSS jammers operating at L-band (~1.
