The IPS UWB anchor positioning system is a solution based on ultra wideband technology, consisting of anchors, tags, gateways, and software. The system supports centralized positioning across multiple regions, floors, and cities, with a typical positioning accuracy of up to 10-30cm. The ultra-low power positioning tags meet the requirements of months and years of ultra long battery life, and the ultra-high concurrency performance makes the anchor and tag capacity almost unlimited. The functions of point map calibration and intelligent diagnosis make system deployment easier. The anchor includes TDOA and AOA anchor, supporting mixed deployment to achieve optimal quantity. Tags include various forms such as bracelets, work cards, and particles to meet the needs of different scenarios. Software opens APIs to meet software integration requirements. The software supports functions such as electronic fences, call alarms, trajectory tracking, and department management, and is widely used in scenarios such as warehousing and logistics, manufacturing factory and safe construction.
