if you expect drones to be used, it makes sense to jam 2.4ghz, 5ghz (communication with drone) and 1.6 ghz (gps signal), maybe some more obscure bands like 900mhz and 3.2ghz (communication with drone) but if you make custom drone that uses, say, 7ghz frequency for communication, that’s outside of normal bands and it’s most likely not jammed because there’s no point if it was never used. just filter everything else out and you’re good to go. jamming only thin bands instead of blanketing everything makes jamming effective over much larger area with the same power. you can even make drone use some band that’s used by, for example, enemy’s radar that’s currently not in area, so that band is not jammed by EW device but also not jammed by radar
But the drone can enter autonomous mode when it happens and direct itself with lidar, gyroscopes and cameras I imagine.
and how it’s guided? as in, how it’s communicated with operator? because it’s happening here. laser in free space would probably require another drone with line of sight to the first one, as a repeater, and this one also needs to be not jammed, otherwise you need line of sight from drone to operator and this would be pretty hard over distances drones are used now
anti-radiation drone (like anti-radiation missile) would be pretty nice idea but this one is clearly guided manually, like every other FPV drone. it would also be much bigger (needs some 15x15cm panel with antennas as seeker at minimum and some circuitry for extracting direction from signal)
Russians are more stupid than I thought then. Jamming commercial bandwidth only is like making armours against commercial weapons only. It’s plain stupid.
For communication you can command it before it get jammed. Automatic mode could either have a target already or find one alone (although this one might be risky).
If you can designate the target while the drone is controlled, then it can direct itself with its own sensors like a missile.
how do you navigate drone in such case? good inertial navigation is expensive and not precise enough unaugmented. GPS will be jammed. TERCOM? i haven’t heard of it being used for cheap drones. what you’re talking about is basically how javelin tracks a target, but this uses some hefty image recognition and is harder than you think

Well, I thought it was something that deserved a news you know.
And I’m pretty sure you can have very accurate inertial positioning, and other sensors can help. At least for a short time.
