Since August 2010, the frequency and duration of GPS jamming attacks from North Korea have increased, prompting the South Korean government to implement the enhanced Loran system, which will cover the whole country by 2016. This is a call blocking application that blocks all radio waves from mobile phones and smartphones.

Last year, 1016 South Korean aircraft and 254 South Korean ships experienced GPS outages during the 16 days of North Korean interference. Mobile deterrent devices are widely used and have produced very positive effects. This ensures that emergency communications can occur without overusing frequencies or weak signals due to the risk of losing connections due to connections.

GPS trackers receive microwave signals from multiple satellite transmitters orbiting the Earth.This project is mainly intended to prevent the usage of mobile phones in places inside its coverage without interfering with the communication channels outside its range, thus providing a cheap and reliable method for blocking mobile communication in the required restricted areas only.

Once the tracker receives signals from four or more satellites, it determines its position through a series of time calculations and trilateration.The answer is that there is counter-drone technology, which has been in the military for years, but the question is how to legally use counter-drone technology outside of war zones without causing all kinds of confusion.
