Yes, afaik the source of issues is GPS jamming.

To add to my point, with multiple antennas it's also possible to spatially separate signals. Not sure if Starlink is doing that, but I think it should be possible to escape GPS jammers by using two antennas with some distance between them. Two antennas can pick up the direction of the signals and with some math they can be separated, at least in theory.
