The system – separate from the military’s programme – would require equipment capable of electromagnetic jamming and spoofing as well as a takeover function that could seize control of an intruding drone and land it using hacking techniques.
Slides presented by the government-controlled National Chung-Shan Institute of Science and Technology (NCSIST), Taiwan’s top weapons developer, at the November 14 briefing said equipment “must possess decoding functions” for OcuSync versions 2, 3, 4 and 4+ – the drone transmission system used by DJI.

The requirement prompted concern that the government was tailoring specifications around a single commercial brand, and questions over whether decoding DJI’s encrypted links was technologically feasible.
