The primary node and secondary nodes are configured to form a hierarchical communication and localization network in which the primary node is associated with a primary hierarchical level and each secondary node is associated with a respective secondary hierarchical level lower than the primary hierarchical level. On the basis of distance measurements and distance-related messages associated with the system, a local reference coordinate system indicative of the positions of the secondary nodes with respect to the primary node is established."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Navigation system for exploring and/or monitoring unknown and/or difficult environments","description":"A navigation system for exploring and/or monitoring unknown and/or difficult environments is provided that includes a mission control module, an unmanned vehicle operable for carrying out the explorat","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8473118","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
