In this study. we propose a tightly coupled integrated method of ultrawideband (UWB) and light detection and ranging (LiDAR)-based simultaneous localization and mapping (SLAM) for global navigation satellite system (GNSS)-denied environments to achieve high-precision positioning with reduced drift. Specifically. we focus on non-line-of-sight (NLOS) identification and correction. https://www.marketingjeunesse.com/product-category/high-gloss-top-coat/
