The rise of the low-altitude economy has been accompanied by frequent chaos caused by unmanned aerial vehicle (UAV) "black flying". Traditional prevention and control measures face the dilemma of "difficulty in detection, difficulty in positioning, and difficulty in disposal". Security incidents such as airport disruptions and intrusions into sensitive areas have been increasing year by year, urgently requiring precise prevention and control technology solutions.

The SDJ202B device relies on the core technology of "on-chip simulation" based on Beidou, integrating two patents (VCO RF signal base architecture and ultra-high power RF enhancement technology). It can simulate multi-system navigation signals, with a 360° coverage range of no less than 500m without obstruction, a response time of less than 10 seconds, support for 24-hour unattended operation, and stable operation in extreme environments ranging from -40℃ to +70℃.

Distinct from traditional wireless voltage suppression, it employs deceptive jamming to achieve precise guidance, eliminating secondary damage. It supports flexible power adjustment to expand the protection range and can simultaneously disperse over 10 drones of different brands, offering both portable deployment and multi-scenario adaptability.

It has been implemented in scenarios such as security for major events, protection of energy facilities, and border control, establishing an integrated defense line of "detection - identification - control - counteraction". It promotes the transformation of low-altitude security from "passive interception" to "active guidance", aligning with the low-altitude security governance requirements outlined in the "14th Five-Year Plan for Digital Economy Development".

Driven by both policy support and market demand, the market size of navigation spoofing equipment is expected to exceed 10 billion yuan by 2027. In the future, it will integrate AI and 5G technologies to achieve multi-target intelligent control, with accuracy improved to the centimeter level.
