The rapid development of the drone market has also driven the development of related industries. As a high-tech product, drones have undoubtedly brought great convenience to people's lives. Many illegal elements can take advantage of this opportunity, they use drones to hinder public safety, and even affect the safety of people's lives and property. The accompanying drone countermeasure equipment ensures the normality of social order. The UAV anti-jammer device blocks the UAV's uplink flight control channel and satellite positioning channel, so that it loses flight control instructions and satellite positioning information, making it unable to fly normally. Different settings will have the control effect of returning, landing and falling. The 2.4GHz/5.8GHz frequency band signal it emits will cut off the drone's flight control signal and satellite positioning signal. When the GNSS navigation system loses the signal, the flight control system and the signal transmission system are out of control, cutting off the connection between the UAV and the ground end of the remote control, the UAV will be forced to land or return to home automatically. Desktop 12 Bands Cell Phone Signal Jammer Multiple Frequencies The drone jammer device suppresses the control signal by transmitting a high-power same-band jamming signal to the UAV, interfering with the sensor, link and positioning system of the target UAV, forcing the UAV to land on its own or Return. After the interference information is sent, the drone and the remote control cannot hear any instructions from the other party at all. At this time, they can only land or return. https://topsignaljammer.com/

Unmanned aerial vehicles are controlled remotely and wirelessly via radio waves. It is an invisible electromagnetic spectrum (frequency in MHz). There should be a transmitter to send the message and a receiver to get the message that the radio waves work. A lot is that the transmitter and receiver must operate at the same frequency. Wireless Remote Control Portable Drone Blocker GPS Frequency WiFi is often used for remote control drone work, such as Aum AR drone 2.0, and the quality of interoperability between drones and mobile applications is very good (computers, tablets, iPads, etc. if there are any). Higher frequencies also have a wider range than lower frequencies, and also bring better sharpness for intensive use, such as 900MHz for drone transmissions. GPS (Global Positioning System) frequencies L1 (1575.42MHz) L2 (1227.60MHz) L5 (1176.45MHz) are used to send location data to the drone control. GNSS (Overall Navigation Satellite System) mainly includes GPS (USD), Gaileo (Europe), Glonass (Russia), BDS (China), QZSS (Japan) and IRNSS (India). The normal frequency is the operation of common drones 433MHz, 900MHz, 1.2G, 2.4G, 5.2G, 5.8G, etc. (430-440MHz, 2.4G-2.4835GHz, 5.15-5.35GHz, 5.725-5.850GHz). As drones become more common around the world, black flies are actually often seen. topsignaljammer provides an absolutely effective solution for drone blackfly - drone jammer. https://topsignaljammer.com/
