A New Challenger Emerges
Blue Origin, a prominent player in the aerospace industry, has put forth a significant endeavor to establish its own satellite internet service, dubbed
TeraWave. This ambitious project aims to deploy a constellation of 5,408 advanced satellites designed to cater to enterprise and governmental clients. The system's potential to rival established services like Starlink has generated considerable attention. SpaceX, which operates the widely used Starlink network, has formally communicated its apprehensions to the Federal Communications Commission (FCC) concerning aspects of TeraWave's operational design. The core of SpaceX's objection lies not in outright rejection of the project, but in specific operational parameters that it believes could lead to substantial disruptions for existing satellite systems, impacting the services relied upon by millions of consumers globally. This early intervention highlights the competitive pressures and the critical importance of spectrum management in the burgeoning satellite internet market.
Spectrum Interference Concerns
The crux of the disagreement between SpaceX and Blue Origin centers on the management of satellite constellations, specifically the radio frequencies used for telemetry, tracking, and command (TT&C) operations. Blue Origin's TeraWave proposal involves utilizing specific frequency bands, including parts of the Ka and E-bands, namely 18.8 to 19.3 GHz, and 71 to 76 GHz, as well as 81 to 86 GHz. This presents a significant overlap with the frequency bands that SpaceX's Starlink constellation already employs for its essential download and gateway transmission functions. SpaceX is particularly worried about Blue Origin's plan to equip its low-Earth orbit satellites with two 'low-gain, omnidirectional Ka- and E-band antennas'. According to SpaceX's assessment, such antennas would broadcast signals over vast areas, akin to continent-sized contours, rather than the narrowly focused beams that are more efficient. This approach would necessitate greater power consumption and render the system more vulnerable to environmental factors like weather, potentially leading to signal degradation and widespread interference for Starlink's operations in these shared frequency spaces.
Proposed Solutions and Objections
SpaceX has articulated a clear set of recommendations to mitigate the potential interference issues arising from Blue Origin's TeraWave project. The company suggests that Blue Origin should transition to utilizing 'high-gain directional E-band links.' These types of antennas are designed to emit radio beams in highly focused directions, significantly reducing the likelihood of stray signals impacting other systems. By adopting this approach, SpaceX argues, Blue Origin could ensure its TT&C operations are conducted without compromising the integrity of the bands currently used for crucial backhaul services and reliable, high-capacity satellite communications. SpaceX emphasizes the FCC's responsibility to ensure that the development of new satellite services does not come at the expense of existing users who depend on these frequencies. Furthermore, SpaceX has expressed skepticism regarding Blue Origin's capacity for good-faith coordination with other satellite operators to preemptively resolve any interference conflicts, underscoring the need for regulatory oversight to safeguard the equitable use of orbital spectrum.
Industry Weighs In
The concerns raised by SpaceX regarding Blue Origin's TeraWave proposal have resonated with other entities operating within the satellite industry. Following the FCC's acceptance of Blue Origin's application for review, several other satellite operators have voiced their own reservations. AST SpaceMobile, an organization developing satellite-to-phone connectivity, has also flagged potential radio interference risks to its forthcoming constellation. They have formally requested that the FCC mandate Blue Origin to present technical evidence and engage in coordination with AST SpaceMobile to avert any detrimental interference. Adding to the opposition, Viasat, another major satellite service provider, has submitted a petition urging the FCC to reject Blue Origin's plans for TeraWave's TT&C operations. Viasat contends that the proposed methods would not only impede more efficient uses of the radio spectrum but also pose unacceptable interference risks to other established operators, reflecting a broader industry concern about the responsible deployment of new satellite technologies.
