Based on domestic UWB chips and the TDOA (Time Difference of Arrival) algorithm, this solution deploys a cluster of three-dimensional positioning base stations. It leverages the nanosecond-level time resolution of ultra-wideband signals to achieve real-time two-dimensional positioning (horizontal X/Y coordinates) with centimeter-level accuracy and a latency of less than 50 milliseconds. The system employs an adaptive anti-multipath interference algorithm to support stable ranging in dynamic environments. Additionally, it reduces deployment complexity by optimizing the topology layout of the base stations (such as diamond or star configurations). The solution incorporates standardized protocol interfaces, allowing users to directly call APIs for device coordinate resolution and trajectory tracking without the need for secondary development. It is suitable for applications such as warehouse AGVs (Automated Guided Vehicles) and intelligent manufacturing workstation monitoring, meeting the requirements for domestic substitution and high reliability.
