> Instead of whining we should start jamming Glonass in retaliation What a ridiculous comment! All GNSS use similar frequencies for civilian signals. 1575 MHz for Galileo, 1600 MHz for Glonass etc. Since jammers primarily work by sweeping a strong signal across the relevant band (more effective than spot frequency jamming), practically all crude attempts to jam one constellation can just as well jam the lot. (You need to be rather more precise just to jam one). e.g. A cheap COTS "GPS" jammer will typically work on all four GNSS constelations.
