Earth station spectrum coordination and interference.

Technologies

• Earth station licensing and coordination Licences and coordination with terrestrial users around each earth station.
• NGSO–GSO interference analysis EPFD and aggregate interference studies that show a non-geostationary system can share with GEO networks.
• Propagation modelling Rain, gas, cloud, scintillation and ionospheric models that set link budgets and availability.
• Interference detection and geolocation Finding and resolving interference using carrier ID, spectrum monitoring and standard reporting.
• Cross-border coordination Coordination of earth stations and terrestrial systems near national borders.
• Protection of radio astronomy and science services Siting and emission limits that protect passive science bands near sensitive observatories.
• Satellite and terrestrial spectrum sharing Studies and tools for satellite services sharing mobile bands, including direct-to-device.
