Space licensing and spectrum: an earth station coordinated with its neighbours before it is switched on. The loop, step by step: 1. Two stations and a receiver at the licence edge. 2. The receiver measures the downlink’s footprint. 3. Each reading is stamped with time and place. 4. The measurement is signed with its position. 5. Power levels reach the compliance rack. 6. The relay forwards sealed packets untouched. 7. Signatures are checked before any model runs. 8. Levels are compared with the licence mask. 9. The edge releases confirmed results only. 10. The filing shows the system inside its mask. 11. The alert arrives with its evidence attached. 12. The regulator receives the coordination file. 13. Sensors check that the response worked. 14. The whole chain is archived for audit. 15. Everything settles back to idle.

Licensing and spectrumLicensing and spectrum, inside Space and satellite systems: ITU filings: advance publication, coordination, notification, NGSO–GSO sharing and EPFD, landing rights and market access, remote sensing licensing and more. Every item is traced to its specification, from ITU RR Art. 9 and Art. 11 to ITU RR Appendix 4 (data for filings), and runs on the open Observatory Protocol.
Plan with usArchitectureThe protocol01What it is
The space segment end to end: orbits and constellations, spacecraft buses, communications and Earth observation payloads, inter-satellite links, tracking and command, space safety, launch, and the licensing and filings that let a system operate over a site. Everything on the ground that talks to spacecraft: gateways and teleports, user terminals, modems and software-defined radio, shared antenna networks, CCSDS protocol stacks, mission control, data processing and the spectrum coordination behind each earth station. Each technology below carries what it is, what we do with it, and the standard it is drawn against.
Satellite and space systems
The filing sequence that secures international recognition of a satellite network's frequencies and orbit.
