Are GPS jammers enemies or friends of aircraft?
Jammers can block radio communications on devices operating on specific radio frequencies within their range by emitting noisy radio carriers. GPS jammers generate 1575.42 Mhz interference to prevent GPS units from receiving correct positioning signals. GPS jammers are usually small, battery powered, and transmit signals within a small radius.
A derivative of the Russian system manufactured in North Korea. It is believed to have similar functionality but at a lower cost on the open market. South Korean intelligence claimed in early 2010 that North Korea purchased a new GPS jammer from Russia. This interferes with GPS reception within a 500km radius, which basically covers the entire Korean peninsula.
South Korean officials reported that the jammer operation, which began in late March, targeted the aircraft's navigation equipment. North Korea reportedly broadcast 100 jamming signals. A total of 962 aircraft were disrupted and nearly 700 fishing boats were affected. The interference also affects cell phone base stations.
The UK government has announced it is doing something because of its views on the threat of drones in the hands of hobbyists. DJI hopes that the multiple guessing quiz will be included as a testing element in the UK licensing scheme. This gives it an additional commercial advantage over its competitors. This amounts to mandatory registration and security testing, or actually a license.
