Passionategeekz On June 20, in MWC2025, Shanghai Tejin, a research and development manufacturer of UAV control system, launched the world’s first base-station low-altitude sensing device based on TDOA (arrival time difference positioning technology), and joined hands with operators to explore a multimodal fusion low-altitude safety supervision system based on 5G-A+TDOA.
According to the relevant person in charge, this device is a low-altitude drone sensing base station, as its name suggests.Mainly used to monitor low-altitude waterway flights, protect important facilities, and avoid “black flights” of dronesAt present, the base station has been deployed in the Hefei low-altitude intelligent network infrastructure demonstration zone, which can realize accurate detection and early warning of unmanned aircraft below 600 meters at a low altitude.
In addition, the relevant person in charge said that the base station was in line with the deployment needs of digital infrastructure at the beginning of its design, and could be installed in a co-located manner with the operator’s communication base station, and did not transmit any electromagnetic signals to ensure that public communications and low-altitude communications are not affected. It realizes low-altitude multi-perception integration with 5G-A synesthesia technology as the core, combined with TDOA (arrival time difference positioning technology), RID (message recognition technology), visual optoelectronics and other technologies, and provides end-to-end guarantee for low-altitude management of drones.
