Welcome to our new post in this post we talk about WRC-23 Achieves a Striking Middle Ground in the Evaluation of Satellite Power Limits .The International Regulators are prepared to allow a technical study to change the satellite transmission power flux density (EPFD) limits on the condition that no regulatory action will be taken until at least 2031 as a result.

More about WRC-23
After weeks of discussions about the review of the Equivalent Power Flux Density (EPFD) limits, a contentious issue in the space industry affecting the non-geostationary (NGSO) satellite signals to avoid interference with Earth exploration satellites, arguments from newcomers to NGSO like SpaceX and Amazon suggest that EPFD rules, made more than a decade ago, have become outdated. This has led to more restrictions than necessary for the protection of satellites in the geostationary orbit (GEO).
Viasat, SES and other GEO operators have warned that changing the rules would jeopardize the regulatory stability that has allowed the space businesses to grow in recent years.
As part of a quadrilateral program operated by the International Telecommunication Union (ITU) to update global spectrum regulations, the proposal to review EPFD limits was on the agenda at the WRC-23 conference that began on November 15 in Dubai.
Supporters of the EPFD review have called for a four-year study process to begin so that proposed regulatory changes can be considered at the next WRC-27 conference.
According to regulatory requirements for final approval in the last phase of WRC-23, scheduled to conclude on December 15, the EPFD technical study should be conducted, and its results reported in WRC-27, but without any regulatory action.
Who is Catherine Gizinski ?
Catherine Gizinski, CEO of space consultancy firm River Advisors, said, “It’s a tough negotiation, with no side claiming victory.” She can make “For the NGSOs, delaying regulatory action on WRC-31 based on the results of these technical studies is a long wait, and opening the door to potential regulatory action for WRC-31 is very soon for [GEO operators].
John Janka, Global Head of Government Affairs and Regulatory at Viasat, who had warned that EPFD changes would deter investment and innovation in GEO, said that the additional breathing room for geostationary players would help protect their networks from interference by NGSO players.
Amazon, which formed a lobbying group with several think tanks to emphasize the importance of EPFD changes, was not immediately available for comment. Telesat, operating a GEO constellation but planning to launch an NGSO network called Lightspeed in 2026, stated that the agreement would be positive for operators.
Elizabeth Nesmith, Senior Director of Regulatory Affairs at Telesat, said that it allows “technical studies that are necessary on a global basis” for proposing changes to EPFD on a global scale. She stated, “If studies show it makes sense, then regulatory action for future WRCs can still be proposed”.
