In the method, the calculating is based on computing THS+TSR from the satellite ephemeris vector, a gateway transmits the SFNP and receives the burst in the slot X within the frame number M of the inroute, and N is greater than or equal to M. A method and system for using ephemeris data for inroute timing is disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multimodal inroute timing synchronization system","description":"A method and system for determining inroute frame timing for a Very Small Aperture Terminal (VSAT) includes receiving an appointment to transmit, on an inroute, at a start of a slot X of a frame numbe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11490347","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.
