How to protect low altitude safety

In recent years, the application of drones has become more and more common, and in daily life, drones can be used for plant protection, mapping, fire fighting, patrol, inspection and so on. In contrast, disorderly flight of drones also occurs from time to time, bringing some security risks, in addition to improving laws and regulations, but also need to be controlled at the technical level.
Shengyuan Intelligent Technology Co., LTD., located in Ningbo, Zhejiang Province, is a company committed to developing drone countermeasures technology. Founded in 2023, the company is positioned in low-altitude airspace management, focusing on the needs of UAV accurate control, committed to UAV accurate identification, accurate positioning and accurate strike technical links, and build a security business system around radio information security technology.
Focus on technical research of low altitude defense accurate identification and positioning
"Drone countermeasures technology, currently in use on the market can probably be divided into three categories. One is blocking, the UAV needs to communicate with the pilot during flight, and also needs to locate by GPS in the sky, we use a high-power interference signal to block these signals, so as to achieve countermeasures; The second category is more used in the military, which will directly use some weapons, such as launching bomb nets, to capture the aircraft; There is also a more advanced technology being developed to generate decoy signals without blocking the drone, or even take over the drone's communication, and make the aircraft do something I can control, such as descending to the position I specify." Sheng Yuan Intelligence technology chief technology officer Wang Ning introduced.

Shengyuan Intelligent Technology brings together senior experts from the field of network security, information protection and radio communication, and has always focused on the research of low-altitude UAV defense technology, and the first "cognitive radio protocol reverse analysis" technology, English abbreviation CRPC, is in a leading position in China. Wang Ning said: "The drone we detected is a non-cooperative object. Non-cooperative objects refer to the technology it uses is not open to us, we fully understand the entire communication system through the project, targeted to detect and identify it, to achieve accurate individual identification, and even the location of some drones, models can be measured, which is our company's most core technology. The technology we target and target is TDOA+, which we combine with the protocol cracking CRPC technology. By sending a signal from a source, the difference in time to different stations is used to figure out its geometric position. In fact, the difference in time reflects its distance difference."

The integration and application of technologies forms the development pattern of the whole industrial chain
The smart technology will integrate a number of technologies to achieve the target UAV "accurate identification", "accurate positioning" and "accurate defense" three functions in one. At present, Shengyuan Intelligent Technology has "submarine shield, outpost, hawk-eye, sky shield" and other multi-form UAV countermeasures products, which are widely used in government agencies, aviation and airports, petroleum and petrochemical, water conservancy and hydropower industries.
Chen Na, deputy general manager of Shengyuan Intelligent technology, introduced: "Our 'submarine shield' is called 'watch and play one', which can detect drones, but also defend against drones, it can work itself to form a closed loop, the main application scenario is some fixed areas, such as camps, positions, oil deos, and some important national strategic infrastructure, political core parts."
With the increasing maturity of civil unmanned aircraft technology, UAV performance is getting better and better, and it has been widely used in agriculture, industry, national defense and rescue command, intelligence acquisition and other industries, and a large number of consumer drones "fly into ordinary people's homes", and more and more "low slow small" drones need to be controlled.
To this end, Rise Intelligent Technology has developed the first domestic "low slow small" UAV detection and warning system based on consumer cameras - "Eagle Eye" series, which innovates the application of self-developed intelligent neural network and artificial AI vision algorithm to ordinary consumer photoelectric cameras, and enables the camera to have UAV detection and warning function through short-term learning and training. It has achieved a major application breakthrough of using consumer-grade cameras as terminal sensors to actively detect and detect, and intelligent identification and early warning "low slow small" drones.
"Our Hawkeye series mainly makes up for the lack of radio products. When the drone is flying, it does not emit any signals, that is, inertial navigation flight, so in the absence of radio signals, there is no way to detect and warn the drone. The photoelectric camera product is a kind of vision, we can actively find no one through visual means." Chen told reporters.
Based on CRPC cognitive radio protocol reverse analysis technology and optoelectronic technology, the multi-series products developed by Rise Intelligent technology can effectively detect and identify the accurate position and flight path of drones through grid and systematic deployment, and accurately interfere with the designated targets in multiple drones. With excellent product technical performance, Gradually form a whole industry chain development pattern covering UAV countermeasure product research and development, low-altitude perimeter protection, air situation data mining, and information service promotion, and weave a "low-altitude safety protection network".
