O3b mPOWER is a communications satellite system owned and operated by 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 IP trunking, cruise line connectivity, disaster ...
On 16 December 2022, the first two of SES's next generation medium Earth orbit (MEO) satellite constellation, O3b mPOWER were successfully launched. O3b mPOWER 3 and 4 were launched on 28 April 2023 and O3b mPOWER 5 and 6 on 12 November 2023, and with six satellites in MEO, the service began commercial operation in April 2024. [42] [43] [44] [45]
Communications satellites in MEO include the O3b and O3b mPOWER constellations for low-latency broadband and data backhaul to maritime, aero and remote locations (with an altitude of 8,063 kilometres, 5,010 mi). [8] Communications satellites to cover the North and South Pole are also put in MEO. [9]
Since 2013, the O3b satellite constellation (in Medium Earth Orbit at an altitude of 8,063 km) claims an end-to-end round-trip latency of 140 ms for data services. Since 2024, the next generation O3b mPOWER constellation has been operating alongside in MEO, offering tens of Mbps to multiple Gbps per service with a latency of about 150 ms [66]

The number of O3b mPOWER satellites ordered was increased to 11 and then 13, and on 16 December 2022, the first two O3b mPOWER satellites were successfully launched, with four more in 2023, and the service began operations alongside the existing O3b constellation in April 2024. [9] [10] [11]
The O3b fleet was initially owned and operated by O3b Networks, which became a wholly owned subsidiary of SES in 2016 [120] Orbiting in Medium Earth orbit (MEO), the first generation satellites are sometimes referred to as "O3b MEO" to more clearly distinguish them from the second generation O3b mPOWER constellation - first launched in 2016 ...
Satellites in each plane would follow circular orbits at an altitude of 1400 kilometers. [1] Each satellite was envisioned to contain all hardware and software needed to route traffic throughout the network, including Earth-to-space in the 28.6-29.1 GHz and 29.5-30.0 GHz bands, space-to Earth in the 18.8-19.3 GHz and 19.7-20.2 GHz bands, and ...
