[Hong Kong, August 12, 2025] – Aerovision Technology Limited (ATL), with its independently developed “Sentry Drone System for Early Alert of GNSS Interference”, after successfully entering one of the 38 government-approved “Regulatory Sandbox” programs in March this year, recently completed a trial run at the China Merchants Godown pier, marking an important step forward for the company in safeguarding the activities of the low-altitude economy.
ATL’s “Sentry Drone System for Early Alert of GNSS Interference” deploys “sentry drones” as a vanguard to detect interference to GNSS signals in the airspace in advance, providing real-time safety alerts for drone flights. The system can be widely applied to drone delivery, inspection, performance, etc, significantly reducing flight risks and offering solid technical support for the development of the low-altitude economy.
ATL has assembled a young and international team, with members from Hong Kong, Mainland China, Indonesia, and Pakistan.
In this project, the company collaborated closely with partners, including China Merchants Godown, Wharf & Transportation Co., Ltd., and FlightPro Drone Solutions, while also receiving strong support from various parties. Through resource sharing and in-depth exchanges, the system was rapidly optimized and implemented. For example, the Civil Aviation Department shared their valuable experience in detecting satellite signal interference; the Hong Kong Productivity Council opened its laboratories to support the team in conducting various tests; and the Hong Kong Applied Science and Technology Research Institute engaged in in-depth technical exchanges, inspiring ideas through the exchange of experiences.
Ms. Mabel Chan, Secretary for Transport and Logistics Bureau, visited China Merchants Godown pier on August 12. During the on-site inspection, she highly praised the scientific research achievements of ATL.
Ms. Mabel Chan said she is confident that once the system successfully “takes off,” it will reduce the safety risks of drone operations, giving the authorities room to discuss lowering drone insurance premiums with the insurance industry, thereby benefiting the overall development of the low-altitude economy.

Ir. Dr. Angus Cheung, Chief Executive Officer of ATL, stated in an exclusive interview: “In recent years, the problem of global satellite signal interference has become increasingly serious, particularly in regions with tense geopolitical situations. Over a year ago, our team developed a GNSS interference monitoring system for high-altitude flights. In response to Hong Kong’s low-altitude economy development needs, we subsequently applied its innovative technological concept to the drone sector. The success of this trial run not only validates the reliability of the technology but also lays a foundation for future advancements in drone defence and interference-correction technologies.”
The success of this trial highlights the significant contributions of ATL’s “Sentry Drone System for Early Alert of GNSS Interference” as a pioneering invention in technological innovation and application. ATL will introduce this innovative technology to the market as soon as possible to enhance the development of the low-altitude economy in Hong Kong and even globally, contributing to the safety and efficiency of the industry.
