Which of the following statements with regard to drone swarms is/are correct ?
- 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 :
Show answer
Answer: B. Statement 1 is wrong: drone swarms usually use radio bands (such as 2.4 or 5.8 GHz), not Terahertz. Statement 2 is correct: drones in a swarm talk to each other to coordinate. Statement 3 is correct: GPS spoofing, which feeds false location signals, is a common counter-drone method. So 2 and 3 only.
Watch for: Terahertz sounds high-tech, so students assume advanced swarms use it.
Why the other options are wrong
- A. Wrong because statements 2 and 3 are correct.
- C. Wrong because swarms do not normally use Terahertz bands.
- D. Wrong because statement 1 is false.
