Viasat CEO, FCC Chair Talk NGSO/GSO Sharing

The 18.8-19.3 GHz and 28.6-29.1 GHz band segments are used by at least six other geostationary orbit satellite operators, and that use has gone on for years without interfering with non-geostationary systems, Viasat CEO Mark Dankberg told FCC Chairwoman Jessica Rosenworcel, per a docket 21-456 filing posted Monday. That compatibility comes by avoiding in-line interference through angular separation between NGSO operations and the GSO arc, Viasat said. It urged the FCC to ensure GSO operators continue to have access to the bands as it looks at updating its NGSO fixed satellite service sharing rules.
