Viasat executive warns that proposed changes to Equivalent Power Flux Density (EPFD) limits could stifle innovation and investment in the geostationary orbit (GEO).
The ongoing WRC-23 conference in Dubai has become a battleground for satellite operators as they debate proposed changes to the Equivalent Power Flux Density (EPFD) limits. These limits determine the transmission power of non-geostationary (NGSO) satellites to avoid interference with geostationary orbit (GEO) spacecraft. While NGSO players like SpaceX and Amazon argue that updating the rules would foster innovation, GEO operators, such as Viasat, contend that the existing regulations strike the right balance. The outcome of this debate could have significant implications for the future of satellite networks and technologies.
NGSO Players Push for EPFD Changes to Support Innovation
NGSO players, including SpaceX and Amazon, advocate for updating the EPFD rules established over a decade ago. They argue that revisiting these limits would create opportunities for innovation in orbits outside of GEO. Amazon recently formed the Alliance for Satellite Broadband, collaborating with think tanks to advocate for EPFD changes, claiming that the current rules hinder NGSO innovation.
GEO Operators Argue for Maintaining the Current Regulatory Regime
On the other hand, GEO operators assert that the current EPFD rules strike the right 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 not only generate more interference but also hinder innovation by other players. Janka emphasizes that the stable regulatory regime has fostered investment in satellite networks and technologies, and any uncertainty could undermine the investment environment.
Middle Ground and Need for Review
While some GEO operators oppose the proposed changes, others, like Telesat, see the value in revisiting the EPFD 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, a review is warranted. Intelsat, another GEO operator, agrees that it is time to reevaluate the rules to ensure they align with current and future technological advancements.
Conclusion:
The debate over proposed changes to EPFD limits at the WRC-23 conference highlights the conflicting interests of NGSO and GEO operators. NGSO players argue that updating the rules would foster innovation, while GEO operators contend that the current regulations strike the right balance. The outcome of this debate will determine the future of satellite networks and technologies, with potential implications for investment and innovation. As negotiations continue at the conference, the industry awaits a resolution that will shape the future of satellite communications.
