On October 21, 2026, at the 2026 North Bund International Shipping Forum Green and Low Carbon Forum, the “In-flight High-Precision Positioning System and Personal Safety Sensing Network” jointly developed by CRIC Tianjin and CCCC Aviation Communications Technology Co., Ltd. was officially released. In response to the industry problem of “the signal cannot enter, the positioning is inaccurate, and the safety cannot be seen” in the steel cabin, the system uses a mesh self-organizing network to spread the communication network into the cabin, and then uses “signal fingerprinting+inertial navigation” to restore personnel positions, stabilizing the positioning accuracy of the key cabin at 3-5 meters, with a typical confidence level of 87%. Among them, the inertial sensing session uses Shanghai SiRui Technology Co., Ltd.'s six-axis IMU, PDR pedestrian inertial guidance algorithm, and fall detection algorithms; the signal fingerprint uses the algorithms of Shenzhen Ancar Intelligent Technology Co., Ltd., so that the position “does not stop or jump” when the signal is blocked, and also allows the system to move further from “knowing where people are” to “knowing whether people are safe”.
