#gps jammer

They first experienced a dropped signal strength from the WiFi signal but once it normalized, the GPS and satellite signals from a few drones completely dropped. One by one, more drones also lost their GPS signals until the entire fleet of drones broke down due to lost satellite connection. Since all the drones could not make any GPS connection, the flight path could not be processed and the launch had to be delayed. Normally, drones would lose GPS signals due to several factors (atmospheric disturbances, weather changes, solar activity) but the most common would be blocked signals like tall buildings or structures, which is why drone live shows are done in an open area. The one experienced during the BLACKPINK Sandbox Drone Show was a total (0%) GPS signal loss on all of the dozen drones used in the event. This can be easily done with a GPS jammer. A GPS jammer is a small self-contained device that blasts electromagnetic noise and radio frequencies to a drone to disrupt its own signal. There are really cheap signal jammers out there so this possibility is something we can't rule out in this instance.
