In September this year, Zhiyang Innovation Technology Co., Ltd. successfully developed the "Xingsun SF-X1" model, which has recently achieved demonstration application. It solves the problem of stable UAV operation in satellite-denied environments, presenting a "Chinese solution" to the "signal black hole" issue that has long troubled the UAV manufacturing industry.

In recent years, UAVs have been widely used in inspection, mapping, and other fields, but they become "immobile" in environments lacking satellite signals such as tunnels and mines. To break the core reliance on satellite signals, the company's team focused on developing alternative autonomous positioning technologies, setting their sights on multi-modal signal fusion positioning technology. By integrating data from various high-precision sensors including inertial navigation and lidar, and performing fusion processing, it equipped the UAV with a "Memory Master" and "compass", achieving centimeter-level precise positioning.
