Abstract
Supplemental Coverage from Space (SCS) poses a significant coexistence challenge for existing and planned radio science systems (e.g. radio astronomy telescopes). Services using satellite constellations to transmit and receive directly to large numbers of mobile devices in the 614 MHz to 2.36 GHz are planned or already in testing (i.e. 38 FCC Rcd 2790(3)). The large scale constellations required for these systems, and the radio transmissions and emissions that result, represent a new and likely unavoidable set of interference sources for radio science systems and applications. We discuss the challenges of this new era and our efforts to model and quantify the impact of SCS on radio science observatories.
