Part of SES's O3B medium-Earth-orbit broadband constellation, providing low-latency internet connectivity to island nations, remote enterprises, maritime vessels, and mobile network operators across the equatorial belt. O3B's unique orbital altitude was specifically chosen as the sweet spot between GEO's excessive latency and LEO's need for hundreds of satellites to achieve continuous coverage.
