- Abstract
- As of August 8, 2024, there are 6,324 Starlink satellites and 634 OneWeb satellites in Earth orbit. The presence of such large-scale Low Earth orbit (LEO) communication satellite constellations can potentially impact Geostationary Earth Orbit (GEO) telecommunication and broadcasting services. Consequently, the International Telecommunication Union (ITU) has established specific regulations to ensure that Non-Geostationary Orbit (NGSO) satellite networks do not cause harmful interference with other satellite systems, particularly GEO satellites. LEO satellites like Starlink and OneWeb could transit the field of view of Earth station antennas aimed at GEO satellites, and in such cases, the communication signals from the LEO satellites must not interfere with those of the GEO satellites. In this paper, we analyze how frequently the 6,324 Starlink satellites and 634 OneWeb satellites currently in orbit pass through the field of view of Earth station antennas aimed at the Koreasat-6 satellite, positioned at 116° East longitude. This analysis is conducted using orbital predictions to evaluate potential interference with communication services.
