In order to prevent terrorism and dangerous behavior from small drones, the National Police Authority has decided to introduce a “radio interference device” that transmits radio interference to drones that fly in the no-fly area without permission and cannot control them. , The transmission of radio interference requires the approval of the Ministry of Internal Affairs and Communications, which is responsible for the Radio Act, and the city police department that uses equipment continues the procedure. Commissioning is scheduled for April.
When the drone is signal jammer by the interfering drone, it slowly sinks, returns to the pilot, stays in place and does not approach the target. The National Police Department increased the budget for fiscal year 2018 by approximately 1.4 billion yen and the budget for fiscal year 19 by the cost of providing equipment for drone measures, including jammers.
From this year to the next year there will be imperial events, from the Abbot of the Emperor and the throne of the Crown Prince, the summit of the 20 most important countries / regions (G20), the Rugby World Cup (W-Cup), the Olympic Games and accompanied to the Paralympic Games in Tokyo. Large numbers of people gathered for such events and it was found that action against drones had to be taken because of the risk of terrorism being targeted.
