SpaceX: Other NGSO Compatibility Values Often Arbitrary

Only Telesat and SpaceX have issued quantitative inference analyses of spectrum sharing among earlier and later processing round non-geostationary orbit satellite systems (see 2407220021), SpaceX said Friday. In a docket 21-456 filing recapping a meeting with FCC Space Bureau staff, SpaceX said the protection proposals from other commenters "involve hand-waving arguments to support arbitrarily-selected values." In a recap of meetings with the offices of Commissioners Geoffrey Starks and Nathan Simington and the Space Bureau, Amazon's Kuiper said it urged the FCC to wrap the proceeding and discussed its recommended protection values.
