FCC gets five new applications for non-geostationary satellite constellations


WASHINGTON — Boeing’s plan to deploy a constellation of V-band satellites in non-geostationary orbit has prompted at least five companies, including SpaceX and OneWeb, to file me-too proposals with the U.S. Federal Communications Commission.

The FCC got given companies until March 1 to reveal if they also had strategies to work with the same V-band that Boeing possessed requested in November of this past year. 

The five companies -- SpaceX, OneWeb, Telesat, O3b Sites and Theia Holdings -- all informed the FCC they may have ideas to field constellations of V-band satellites in non-geosynchronous orbits to provide marketing communications services in america and elsewhere. Up to now the V-band spectral range of interest, which rests straight above Ka-band from about 37 GHz to the reduced 50 GHz range, is not heavily useful for commercial marketing communications services.


Boeing also submitted a new application to the agency asking to use the 37.5 to 42.5 GHz range of V-band for downlinking from spacecraft to terminals on Earth, and two other swaths, (47.2 to 50.2 GHz and 50.4 to 52.4 GHz) for uplinking back to the satellites. The company’s proposed constellation would consist of 1,396 to 2,956 low-Earth orbit (LEO) satellites for providing connectivity. The FCC originally deferred on Boeing’s request to operate in 42 to 42.5 and the 51.4 to 52.4 GHz range back in November.

The wave of new applications follows those that 11 companies, including Boeing, filed in November when the FCC set a deadline for any operators to come forward if they had plans to operate in the same bands that OneWeb proposed for its constellation of low-Earth-orbiting internet satellites. All of the companies that met the FCC’s March 1 deadline for V-band plans had participated in the November processing round as well.

Most companies are describing their potential use of V-band satellites as follow-ons to pre-existing plans for constellations in Ku- or Ka-band. SpaceX, for example, proposes a “VLEO,” or V-band low-Earth orbit (LEO) constellation of 7,518 satellites to follow the operator’s initially proposed 4,425 satellites that would function in Ka- and Ku-band. Canada-based Telesat describes its V-band LEO constellation as one that “will follow closely the design of the Ka-band LEO Constellation,” also using 117 satellites (not counting spares) as a second-generation overlay.

Newcomer Theia asked the FCC to allow it to use V-band frequencies for gateways on the ground that would have originally only used Ka-band. The company wants to operate a constellation of satellites for both communications and remote sensing, and claims that because its spacecraft will have “regenerative” payloads, that “there is no specific relationship between V-band uplink frequency bands and downlink frequency bands.”


MEO V-band

OneWeb informed the FCC it wishes to use a "sub-constellation" of 720 LEO V-band satellites at 1,200 kilometers, and another constellation in Medium Globe Orbit (MEO) of just one 1,280 satellites. Added jointly, that expands the OneWeb constellation by 2,000 satellites -- a move the business said the other day that it could choose making by the finish of this yr. OneWeb said in its March 1 filings that the business would "dynamically assign traffic" between your LEO and MEO V-band constellations predicated on service requirements and the info traffic within coverage areas.

OneWeb's request for MEO follows that of ViaSat's in November for 24 MEO satellites to augment ViaSat-3, the business's trio of terabit-per-second-throughput satellites presently underway. ViaSat bundled its obtain use of V-band using its software for MEO Ka-band jointly. O3b this March told the FCC so it wants market usage of V-band for 24 additional satellites that could operate in a circular equatorial orbit as a constellation called O3bN.
