O3b mPOWER

O3b mPOWER is a communications satellite system owned and operated by the Luxembourgish company SES. The system uses high-throughput and low-latency satellites in a medium Earth orbit (MEO), along with ground infrastructure and intelligent software, to provide multiple terabits of global broadband connectivity for applications including cellular backhaul and international IPtrunking, cruise line connectivity, disaster recovery, and military communications. The first O3b mPOWER satellites were launched in December 2022 and the system became operational in April 2024 with 6 satellites. Two further satellites were launched in December 2024, and the system's capacity will be increased by a further 5 satellites launched by 2026.

The O3b mPOWER satellites use fully shapable and steerable spot beams that can be shifted and scaled in real time to suit individual users. The satellites join SES' existing constellation of 20 first-generation O3b satellites in MEO and they can be used in conjunction with them, with the SES's fleet of geostationary satellites, and with SpaceX's Starlinklow Earth orbit (LEO)satellite constellation, providing full multi-orbit capability.
