The ‘insurgents’ in Iraq and Afghanistan have had some success in shooting down large fast flying US military drones – similar to the BAU Herti – using small arms fire; AK47s etc (currently unavailable at Maplins), so the slower moving Microdrones should be easy prey to automatic weapons fire – the obvious problem is that such weapons are illegal (in the UK) and not exactly subtle when used in a ‘public order’ environment.
For taking out Microdrones a (slightly) more legal option might be a paint ball gun which fires large calibre low velocity paint capsules that will blind as well as damage the target. Paint ball guns have the advantage of being legal and commonly available but again, probably not the best choice for riots and demonstrations. For these occasions, the simple hand held catapult firing a range of improvised ammunition should do the job though surreptitiously hitting a moving 1m sized target at a range of, say, 100 metres may require a little target practise…and may take a few shots as the drone can still fly with only two of its four rotors functioning.
Jamming the control and navigation signals should be an effective way of disabling the drones – jammers work within a fixed range radius rather than having to be targeted and have the added benefit of being non-destructive – allowing the capture and re-use of the confused drone…
Radio Control Frequency
The Microdrone uses the same radio control method as model RC aircraft to direct it’s flighpath. The exact frequency used by the police probably falls within theUK frequency regulations for RC aircraft otherwise RC frequencies can easily be scanned and jammed using RF jammers for selected frequencies or more crudely saturate the whole spectrum.
Build your own RF Jammer:
“If you want to saturate the bandwidth, you use an analog device with simple FM modulation. Eight 2.4Ghz wireless video transmitters of sufficient power would do it.”
The Hicam Microdrones navigate using standard GPS, which is particularly sensitive to jamming. There are a number of portable GPS jammers on the market or for a few quid you can build your own…
