A navigation system and associated methods are also described that include a laser positioning system. A navigation system and associated methods are described that include an RF positioning system. In one example, the laser positioning system, and the RF positioning system cross check one another to ensure reliability and accuracy of a position measurement."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Navigation system and method","description":"A navigation system and associate methods are described that include a plurality of fixed terrestrial based reference devices that calibrate the system by tracking positional error between the fixed t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9689963","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.
