Harmonic and intermodulation emission from direct-to-device satellites - Harmonics of the Starlink 2.6 GHz downlink and the products around them
Balthasar Indermuehle, Benjamin Winkel, Federico Di Vruno +2
Direct-to-device (DTD) satellites carry mobile base stations transmitting in terrestrial mobile bands. Their non-linear emission products can fall into radio astronomy bands, inclu…
A measurement-based approach to EPFD calculation, to quantify the impact of satellite mega-constellations on low-frequency radio astronomy
Steven J. Tingay, Gregory Hellbourg, Daniel Sheen +4
Context: Satellite mega-constellations generate Unintended Electro-Magnetic Radiation (UEMR) impacting low frequency radio astronomy. The Radio Regulations of the International Tel…
Modelling steerable beams of satellite constellations for radio astronomy impact studies
Federico Di Vruno, Gary Hovey
Modelling is essential for studies that quantify the impact from satellite downlinks on radio astronomy sites. To estimate this impact it is necessary to know not only the position…
Summary of SatHub, and the current observational status of satellite constellations
Mike W. Peel, Siegfried Eggl, Meredith Rawls +4
SatHub is one of the four hubs of the IAU Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference (CPS). It focuses on observations, data anal…
Preserving your skies since 1988 -- Committee on Radio Astronomy Frequencies (CRAF) -- Periodic Review 2011-2021
Committee on Radio Astronomy Frequencies, Benjamin Winkel, Simon Garrington +43
The Committee on Radio Astronomy Frequencies (CRAF) is an Expert Committee of the European Science Foundation. It aims to provide a cost-effective single voice on frequency protect…
Large Satellite Constellations and Their Potential Impact on VGOS Operations
Federico Di Vruno, Vincenza Tornatore
Large LEO satellite constellations (or so-called Mega-constellations) will significantly change the view of the sky in some radio frequency bands. For VGOS telescopes it is importa…
Unintended electromagnetic radiation from Starlink satellites detected with LOFAR between 110 and 188 MHz
F. Di Vruno, B. Winkel, C. G. Bassa +4
We report on observations of 68 satellites belonging to the SpaceX Starlink constellation with the LOFAR radio telescope. Radiation associated with Starlink satellites was detected…
The Case for Space Environmentalism
A. Lawrence, M. L. Rawls, M. Jah +8
The shell bound by the Karman line at a height of 80 to 100km above the Earth's surface, and Geosynchronous Orbit, at 36,000km, is defined as the orbital space surrounding the Eart…
