Is there not anything similar to a cell phone jammer for RC?
Would also be cool if they can send out an overriding "return to home" signal that will make the drones return to their starting position. This is something that would need to be in the hardware or firmware or to where the device would be bricked if removed from there or software.
- mips_avatar 7y agoGPS jamming would be more effective. The flight computer relies on it heavily.
- missosoup 7y agoFor older consumer products yes. For new ones or military purpose, nah. Optical flow + vSLAM + IMU is now the primary localisation system. GPS is just there to stay on track for long paths.
- kevingadd 7y agoThere are a bunch of different frequency ranges they can use, and it's not trivial to jam lots of frequencies without running into legal issues. If you figured out what frequency range the drone is using you might be able to drown it out but the odds seem high that other equipment might be using that frequency band and it could interfere with emergency operations. Like, hypothetical example - a long range hobbyist drone might be hooked up with a SIM card and the cellular network, so blocking it would require blocking cells like the ones used by emergency responders. Shorter range drones are probably using unlicensed bands, and you might be able to block those - but again emergency responders might be using them for short range communications equipment etc. Long range jamming also runs into power issues due to the inverse square law, I think. You'd need to do it directionally, and at that point I think you'd be better off just shooting the drone down with something like a gas-powered BB rifle or net launcher.
