About

Zhili Xu is a leading researcher in the field of seamless navigation and multi-sensor fusion, with a primary focus on enabling robust positioning for unmanned ground vehicles (UGVs) across complex indoor and outdoor environments. His most cited work introduces a tightly coupled integration of precise point positioning (PPP), inertial navigation systems (INS), and ultra-wideband (UWB) technology, achieving centimeter-level accuracy without the need for a reference station. This breakthrough directly addresses the critical challenge of ubiquitous availability in mobile robotics, bridging the gap between GPS-denied indoor spaces and open outdoor areas. With 23 citations on this seminal paper alone, Xu’s contributions are shaping the next generation of low-cost, high-reliability autonomous navigation systems. His research is particularly notable for its practical application to low-cost UGVs, making advanced positioning accessible for real-world deployment in logistics, inspection, and emergency response. By solving the long-standing problem of seamless indoor-outdoor transitions, Zhili Xu is paving the way for truly autonomous mobile robots that can operate anywhere, anytime.
