Interfering signal equipment is becoming more and more popular from Greatjammer's blog

The jammer can effectively resist drones several kilometers away. Generally, GPS jammer operate at the distance ratio between the drone and the jammer compared to the drone and its pilot. The farther the drone is from the pilot and the closer it is to the jammer, the better. The typical effective jammer direction is a cone of about 15 to 30 degrees, extending forward from the spray gun (this is also affected by the RF frequency band and jammer power). This kind of jamming weapon is also the main direction of weapon research in recent years. It has the effects of high efficiency, small accident damage and low loss. Currently, the device can disable enemy drones and GPS weapons.

ISignal interference has become an increasingly popular tool for criminals to steal vehicles and goods, and truck hijacking is estimated to cost the country 3 billion rand in 2015.

In almost all reported hijacking incidents, the truck tracking signal was not available because the suspect used it more destructively.

During the "State Statement" speech held in Pretoria in 2015, the exposure of the power of attorney and the blockade of mobile communications caused the scourge of signal congestion in South Africa. The latter is particularly helpful in raising public awareness and leading companies such as Ctrack to innovate and defend themselves.

However, the use of signal jammer continues to spread in South Africa because they are easily available and cheaper. As a result, today's hijackers use a variety of jamming systems and devices, some of which are large and heavy, and some are small and easy to carry. Despite the fact that it is illegal to own and/or use ICASA signal jammers in South Africa.

The drone jammer system (technically known as the sd-10a laser headspace system) uses advanced optoelectronic technology. Through the rough tracking of the radar search, the precise tracking of the photoelectric system and the precise strike of the high-energy laser, it can destroy the small UAV in a few seconds. The system can be widely used in military and civilian fields to respond to fast and brisk strikes.
