Obtain and Deploy Drone Jammers to Halt Drone Activity


In an era where drones are increasingly prevalent, the importance of drone jammers cannot be overstated. These devices have become a common feature in both commercial and recreational contexts. As the drone population expands, it is crucial to adopt security strategies to counteract the threat posed by unauthorized aerial intrusions.

Devices that prevent unauthorized drone operations work by interrupting the communication link between the drone and its controller. This technology is categorized as anti-drone technology, employing sophisticated methods to block signals and incapacitate drones. By transmitting radio frequencies that interfere with the signals necessary for drone functionality, these jammers can effectively ground drones, thereby protecting your privacy and security.

The term “blocker” in the advertisement for the circuit we have purchased might lead the naive and technically unskilled customer to imagine that the radio frequency signal from the GPS constellation is miraculously canceled in the vicinity of the receiver. Even a destructive interference solution would only be local, excessively complex to adjust, and difficult to implement on the GPS broadband CDMA signal. In practice, we purchased the most despicable signal jammers imaginable: a sawtooth-shaped signal generator (the venerable NE555) biases the adjustment voltage of a microwave oscillator around 1.575 GHz.

As all these components drift terribly with the environmental conditions, and in particular the temperature, in the absence of quartz or frequency control, the swept frequency range is largely superior to the 2 MHz bandwidth of GPS: the triangular signal coming from the NE555 induces a sweep of the microwave oscillator on the range 1.55 to 1.59 GHz. By chance or proximity to Russia, the 1.6 GHz GLONASS band (1602.0-1615.5 MHz) is at the limit of the interference band and is not too much affected by the signal jammer.

Each GPS bit occupies 20 ms (transmission at 50 bps), and each bit is encoded by 20 repetitions of the pseudo-random code that represents each satellite, a code of 1023 bits in length transmitted at a rate of 1.023 Mb/s (thus repeating the code every millisecond). By clicking the NE555 at about 300 kHz, we are in the order of magnitude of the repetition rate of the code identifying each satellite, ensuring that the receiver cannot find the original signal.

Key Features to Consider

Key features such as frequency range, output power, and portability are crucial when choosing a drone jammers. Frequency range determines which signals the jammer can block, while output power affects the effective range of the device. Choosing the right drone jammer is not just about power, but also about accuracy and adaptability to different environments. To choose the right drone jammer, evaluate the typical drone activity in your area and the size of the area you wish to protect.

Deployment strategies for drone jammers

Strategic planning is essential for the effective deployment of drone jammers. It is vital to evaluate the layout of the environment, anticipate drone flight patterns, and identify any potential obstacles that may affect the jammers' range. Ongoing testing and drills will ensure that the equipment is prepared to operate at optimal levels when it is most critical.

  • Test your jammer in different locations.
  • Keep your devices charged and ready.
  • Update the firmware regularly to ensure optimal performance.

It is crucial to understand that even the best technology can face obstacles. Common problems associated with drone jammers include signal interference, limited range, and power issues. Detailed manuals and customer support can play a vital role in troubleshooting these challenges, thereby maintaining the effectiveness of your jammer.
