Have you noticed that the sky is getting busier and busier. In Shenzhen shopping malls, drones rise and fall in an orderly manner, and takeout falls from the sky; In Pingdu, Qingdao, farmers use plant protection drones to sow and fertilize crops, saving time and effort in managing farmland; In Mount Huangshan, Anhui Province, drones are used to carry goods up the mountain from the air... More and more unmanned application scenarios have entered our lives. Behind this lies the joint efforts of ground surveillance, communication, navigation equipment, low altitude airspace control systems, as well as drones, navigation aircraft, and other aircraft. Recently, the relevant departments jointly issued the Implementation Plan for Innovative Application of General Aviation Equipment (2024-2030), which encourages local governments to incorporate low altitude infrastructure into urban construction plans and strengthen connections with urban transportation systems. How to fully utilize the airspace resources below 1000 meters in the context of urban land resources? Well, the three-dimensional transportation network of the city has been updated. With the low sound of the propellers, an electric vertical takeoff and landing aircraft (eVTOL) capable of carrying 5 people and cruising at a speed of up to 200 kilometers per hour takes off slowly from the Shenzhen Shekou Cruise Home Port, without the need for traditional airports and runways, and can fly to Zhuhai in just 20 minutes. At present, this cross city trip takes nearly 3 hours by car and over an hour by boat. It is reported that this is the world's first eVTOL cross sea and cross city flight. After obtaining an airworthiness certificate, it is expected to start manned flights in 2026. To fly, it is even more important to fly safely. How to provide safety guarantees for low altitude flights with dense, large volume, and scattered points, from taking sightseeing helicopters for a ride, to adding "air taxi" routes, and then conducting urban air traffic pilots? At the beginning of this year, Rice Information from China Electronics Technology Institute 28 won the bid for the Anhui Province Low Altitude Flight Service Platform Project for New Technology Integration Application. It is understood that the project adopts new technologies such as multi-source heterogeneous data fusion and quantum security to build a low altitude flight service platform that integrates flight situation monitoring, aviation airspace management, flight plan management, navigation intelligence, meteorological intelligence, data management, and statistical analysis functions. It can effectively perceive and manage low altitude flight activities in an orderly manner. "We continuously optimize the system's airspace planning, flight safety assurance and other functions, accelerate the development progress of low altitude flight service software." According to project expert Su Zuhui, after the project is completed, it will fully empower local low altitude flight support, improve flight operation efficiency and safety level. "This point has a suitable height, less obstruction, and is suitable for deployment." This is Li Hua, a senior engineer at China Electronics Technology Corporation's 36th Institute, commanding the anti drone team on site to confirm the layout of the control point, in order to improve the probability of discovery, positioning accuracy, and disposal efficiency. "During the Hangzhou Asian Games, we installed radio and navigation interference detection equipment around key facilities such as competition venues and airports, and integrated radar, optoelectronic and other technical means to build a comprehensive unmanned aerial vehicle countermeasure system." Li Hua introduced that the system has intelligent recognition function, which can quickly identify the model, flight trajectory, and intention of the target drone, and quickly and accurately lock the target drone through high-precision sensors and algorithm analysis. New technologies are taking root and sprouting, and new scenes are emerging - Nanjing, Jiangsu, China,
