Proposal to Review Satellite Transmission Power Limits Sparks Debate on Innovation in Geostationary Orbit

The discussion at the WRC-23 conference on updating global spectrum rules has ignited a debate on the potential impact of reviewing Equivalent Power Flux Density (EPFD) limits for non-geostationary satellite signals. While NGSO players argue that updating the rules would support innovation, GEO operators caution against potential disruptions to investment and technological advancements.

The ongoing WRC-23 conference in Dubai has become a battleground for satellite operators, with a proposal to review Equivalent Power Flux Density (EPFD) limits taking center stage. The outcome of this debate could have significant implications for the future of satellite transmission power and innovation in geostationary orbit (GEO). NGSO players, led by SpaceX and Amazon, argue that updating EPFD rules would foster innovation in orbits outside of GEO. However, GEO operators, such as Viasat, caution that changing the rules would stifle investment and hinder the deployment of advanced satellite technologies.

NGSO Players Advocate for EPFD Rule Changes to Foster Innovation

NGSO players, including SpaceX and Amazon, are pushing for the revision of EPFD rules established over a decade ago. They argue that updating these rules would create a more favorable environment for innovation in orbits outside of GEO. Amazon has even formed the Alliance for Satellite Broadband with several think tanks to advocate for EPFD changes, claiming that the current rules are impeding the progress of NGSO innovation.

GEO Operators Argue for Maintaining the Status Quo

GEO operators, on the other hand, assert that the current EPFD rules strike a balance between protecting their interests and supporting NGSO newcomers. Viasat’s global chief of government affairs and regulatory officer, John Janka, warns that changing the rules would hinder innovation by others, including the deployment of higher throughput satellites and smaller, more cost-effective antennas. Janka emphasizes the importance of a stable regulatory regime that has facilitated investment in satellite networks and technologies in recent years.

The Potential Impact on Investment and Startups

Janka further contends that the uncertainty surrounding a potential change in EPFD rules would disrupt the investment environment, particularly for startups. He argues that self-funded companies would still be able to invest, while those reliant on external funding would face increased risk. The proposal to review EPFD rules could create an environment that favors megaconstellations over startups, potentially stifling competition and hindering the growth of the satellite industry.

Seeking a Middle Ground

While some GEO operators vehemently oppose the proposed review of EPFD rules, others, such as Telesat and Intelsat, see merit in revisiting the rules within the context of a modern space economy. Telesat’s senior director for regulatory issues, Elisabeth Neasmith, suggests that even if no changes are made, it is worth considering the rules in light of the evolving industry. Intelsat, which plans to launch an NGSO constellation in 2027, believes that reviewing the rules is necessary to ensure they align with current and future technological advancements.

Conclusion:

The debate over reviewing EPFD limits at the WRC-23 conference has highlighted the divergent perspectives of satellite operators. While NGSO players advocate for rule changes to foster innovation, GEO operators caution against potential disruptions to investment and technological advancements. The outcome of this debate will shape the future of satellite transmission power and could have far-reaching implications for the satellite industry as a whole. As negotiations continue at the conference, the industry awaits a resolution that strikes a balance between supporting innovation and ensuring a stable investment environment.
