This subway environment, with a depth of 1.4 km and a labyrinthine network of metal tunnels, is notoriously hostile to traditional positioning systems. <\/p>\n\n<p>To meet that challenge, the Australian company implemented a hybrid system that combines its Boreas D90 fiber-optic gyroscope with a laser velocity sensor (LVS), eliminating the need for external signals. The integration is managed by AdNav OS Fusion, a platform that calibrates the reliability of each sensor in real time. <\/p>\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Advanced Navigation Conquers Europe\u2019s Deepest Mine Without GNSS or Fixed Infrastructure\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/axQyqJznXZk?start=2&#038;feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n<p><\/p>\n\n<p class=\"has-text-align-center\">The system combines a laser speed sensor with the Boreas D90 fiber optic gyroscope and an inertial navigation system.
