Week in Space Data, every Friday.
Satellite frequency allocations, filings, auctions, and spectrum coordination
Primary mobile satellite band. Used by Iridium, Inmarsat, and Globalstar for voice and low-data-rate services.
Used for Earth exploration satellite service and space research. Shared with terrestrial mobile services in many regions.
Heavily congested band undergoing transition. FCC C-band auction reallocated 3.7-3.98 GHz to 5G. Legacy satellite operators being relocated.
Primarily reserved for military communications, radar, and Earth exploration satellite services. Limited commercial access.
Workhorse band for DTH television and VSAT services. Increasingly used by NGSO constellations like OneWeb.
High-throughput band critical for next-gen broadband constellations. Active coordination between Starlink, Kuiper, and Lightspeed systems.
Largely unallocated band with potential for future high-capacity satellite links. Research and experimental use ongoing.
Emerging band with large bandwidth availability. SpaceX has filed for V-band NGSO operations. High atmospheric attenuation limits ground use.
