Starlink to test new satellite limits in Romania

The test will investigate the potential for relaxed power flux density (EPFD) limits, possibly allowing Starlink to increase its operational capacity significantly.
India accelerates its push for home-grown Earth observation satellites with a new private-public initiative.

In partnership with Romania’s National Authority for Communications Administration and Regulation (ANCOM) and the Ministry of National Defence, Starlink is conducting an innovative real-world test to assess whether its non-geostationary satellite (NGSO) systems can operate without interfering with geostationary satellite (GSO) networks. The test aims to investigate relaxed power flux density (EPFD) limits, which, if successful, could enable Starlink satellites to operate at up to eight times the current capacity allowed by the International Telecommunication Union (ITU) while ensuring the protection of GSO networks.

Moreover, the existing EPFD limits, established 25 years ago, were designed to prevent unacceptable interference with GSO Fixed Satellite Service (FSS) and Broadcasting Satellite Service (BSS) networks. However, many experts contend that these limits may no longer be relevant. Consequently, ANCOM has initiated this testing campaign to contribute valuable insights to ongoing ITU studies regarding EPFD limits and their implications for GSO networks.

Furthermore, the test includes installing equipment to monitor signal and interference levels, with specific protection criteria set at a 10% aggregate increase in service unavailability and a 3% increase in individual service unavailability. Over the course of at least six months, SpaceX will exceed the current EPFD limits in a designated area to collect essential operational data.

The findings will subsequently be presented at ITU meetings to demonstrate that efficient NGSO operations can coexist harmoniously with GSO networks. Additionally, Romania underscores the importance of establishing a regulatory framework that balances the protection of geostationary networks with the potential of NGSO networks to enhance connectivity. As a result, ITU is set to review EPFD limits at the upcoming World Radiocommunication Conference (WRC-27), where Romania will advocate for a collaborative approach to harness both types of satellites effectively.
