Nanjing Maritime Bureau to build the country's first intelligent three-dimensional cruise system based on 5G low altitude intelligent networking support, the use of drones on the Nanjing section of the Yangtze River, 98 kilometers to carry out regular cruising.
Recently, the first flight of the ET9 prototype of the electric vertical take-off and landing airplane (eVTOL) developed by YVT (Nanjing) Aviation Technology Co.
The newly developed UAV of AVIC Jincheng Unmanned Systems Co., Ltd. is characterized by high intelligence, high wind resistance level and long endurance, which can be used to carry out a variety of aerial tasks such as emergency communication, field operation, disaster relief and rescue, and environmental monitoring.Nanjing is seizing the "wind".spread wings and soar (idiom); to take wingAccelerating the Race for the "City of Low Altitude"
At present, the city has gathered hundreds of aerospace enterprises, covering low altitude manufacturing represented by Changkong Technology and AVIC Jincheng Unmanned Systems, low altitude protection represented by Nanjing Intelligent Aviation Research Institute and China Unicom Low Altitude Intelligent Networking Innovation Center, low altitude flight represented by Dawei Aviation and Tianze Zhicheng, and low altitude comprehensive services represented by Beidou Intelligent Union, Mai Jieke, and Mode Phantom Sky, and other fields.
Expanding application scenarios
Low-altitude economy "flying" higher
Pukou Hi-tech Zone, "Nanjing low altitude service management platform" screen, the city's air routes, no-fly zones, take-off and landing points, registered pilots and other information is clearly visible.
Back in October 2020, NJ had a drone base thatis the first in the province and one of the first 13 civil unmanned aerial test areas in the country.Today, it has built "two platforms, three airspaces and multiple fields".
First flight of the "air cab"
"Flash Delivery" on the river.
Drone blood transportation across rivers

Drone blood transportation across rivers
The staff loaded the blood reefer into the drone, and then operated the drone to fly from Nanjing Red Cross Blood Center to the outpatient building of Pukou District People's Hospital to carry out the blood transportation task.
Efficient pesticide spraying by drones
In the fields of Shizhulin Community, Yishan Street, Liuha District, agricultural drones took off from the wheat fields, spraying pesticides efficiently to provide a guarantee for increased wheat harvest and production.
"Little Blue Whale" Drone Intelligent Cruise
Recently, Nanjing public transport first 5G + "small blue whale" drone in Maqun transfer center officially took off, opened the first drone air cruise. It is understood thatThe first drone airport was established at the Maqun Interchange, theThe supporting UAV remote control system can be connected to the group's command and control center in real time, providing timely and reliable basis for reasonable vehicle scheduling and shift arrangement.
Competing in the new track of "low altitude economy".
How can Nanjing "fly high" with its wings?A number of new technologies are "on the verge of emergence" and have accumulated a large number of technological advantages.
The National Key Laboratory of Air Traffic Management System (NKLATMS) built by EKLAS and XXVIII is positioned to solve the key core problems of the air traffic control mode spanning from the ground to the air-ground coordination, and the control capability leaping from the minute level to the second level.
Ding Hui, deputy director of the laboratory, introduced the "One of the current priorities is to develop the 'Low Altitude Intelligence Plus' platform, which is a low altitude flight management platform. It allows for airspace management, meteorological information intelligence services, and related regulatory services, so that low-altitude aircraft can fly safely and efficiently.Currently, the development and construction of the platform is going very well and there are already pilot applications."
The low-altitude flight management platform that the National Key Laboratory of Air Traffic Management System is working on, in fact, has already had a "high-altitude version" - theThe National Traffic Management System (NTMS) built by Les Information, a subsidiary of ETCO Les, is the only nationwide flight traffic management platform for civil aviation flights in China.According to statistics, the average delay has been reduced by approximately 331 TP3T since the National Flow Management System went live in 2020.
It is reported that "the laboratory's technological heritage and practical experience in civil aviation air traffic control, airport management, and smart cities can help the technical research in the low-altitude field."
The National Key Laboratory of Aerospace Structural Mechanics and Control, which relies on Nanjing University of Aeronautics and Astronautics, also has good news. According to Lu Tianjian, a professor at the lab and a doctoral director, the"We're figuring out a charging system for drones, trying to develop drones that charge while they fly, and there are preliminary results as well."With the further development of the low-altitude economy in the future, there will inevitably be a large number of cross-city transportation scenarios, "We need to make drones able to fly farther before they can do so. In addition, charging while flying can also improve efficiency and reduce costs."
The supporting disciplines of the National Key Laboratory of Mechanics and Control of Aerospace Structures include the three national "double first-class" construction disciplines of Nanjing University of Aeronautics and Astronautics (NUAA), i.e. mechanics, aeronautical and astronautical sciences and technology, and control sciences and engineering, as well as the disciplines of mechanical engineering, materials science and engineering, and information engineering.
"Mechanics belongs to the basic disciplines. From small drones and small airplanes to large airplanes and oversized spacecraft, they are all supported by mechanics."Lu Tianjian introduced that the laboratory is currently conducting research around key scientific and technological issues to support the structural design of aerospace equipment and improve performance and reliability.
China Network Weitong is an enterprise positioned as a "single champion of satellite-based Internet of Things service-oriented manufacturing", and its independently designed, developed and produced mobile weather stations, satellite vehicle-mounted earth stations (Ku/Ka), satellite portable earth stations (Ku/Ka) and other major products are widely used in the meteorological, environmental protection, security supervision, land and other industries.An integrated air, space and geographic emergency communications network has been established.
"Technicians are conducting remote sensing tests of the newly developed low-orbit satellite communication technology, which can significantly reduce communication costs. According to our calculations, it can reduce the original expenditure by 30%." According to Sun Jun, Director of Intellectual Property and Strategy Department of Nanjing Zhongwang Satellite Communication, "the company's previous main research direction is focused on high-orbit satellite communications, and in these years, with the increase in national launches of low-orbit satellites, it has been laid out to carry out research related to low-orbit satellite constellation communications and has achieved certain results.The relevant technology can be directly applied to low-altitude warpJeep communication not only helps to realize remote control and data monitoring, but also provides high-speed data transmission services."
