Licensing and spectrumFilings, coordination and earth-station rules, by country.
Licensing and spectrum, inside Space and satellite systems: earth station licensing and coordination, NGSO–GSO interference analysis, propagation modelling, interference detection and geolocation and more. Every item is traced to its specification, from ITU RR Appendix 7 to ISED Canada earth station licensing, and runs on the open Observatory Protocol.

01What it is
Earth station spectrum coordination and interference.
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. 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. Each technology below carries what it is, what we do with it, and the standard it is drawn against.
