1. They use Terahertz band of frequency to communicate with the command centre.
2. Individual drones in the swarm can communicate with other drones in the swarm.
3. GPS Spoofing is a commonly used technique to counter drone swarm attack.
Select the answer using the code given below:
(a) 1 only · (b) 2 and 3 only · (c) 1 and 2 only · (d) 1, 2 and 3
उत्तर और व्याख्या · explanation in English
Answer: (b) केवल 2 और 3
A drone swarm is a large group of small unmanned systems that work together on a mission, and GPS spoofing is one of the recognised counter-UAS techniques.
- ✗ 1. UPSC's official key treats this statement as incorrect; we could not confirm the detail from an official source, so we do not explain it here.
- ✓ 2. A swarm is a group of drones that act together on one mission (PIB, DARPA). UPSC's official key treats the statement as correct; we could not confirm the rest of the detail from an official source, so we do not explain it here.
- ✓ 3. The NATO Science and Technology Organization lists GPS spoofing, with RF jamming, high-power lasers, EMP and projectile guns, among counter-UAS measures against small UAVs.
Remember · Swarm = many drones acting together on a mission. Counter-drone tools: RF jamming, GPS spoofing, lasers, EMP, projectile guns.
