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]
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]
In August 2023, SES announced that the start of commercial service of the O3b mPOWER system would now be by the end of 2023, with the launch of the fifth and sixth O3b mPOWER satellites (required for commercial service) in Q3 2023, and that the SES-17 high-throughput GEO satellite (launched 2021) and the O3b mPOWER MEO system now have a ...
The O3b constellation orbits at 8,062 km, with RTT latency of approximately 125 ms. [36] The network is also designed for much higher throughput with links well in excess of 1 Gbit/s. The next generation O3b mPOWER constellation shares the same orbit and delivers from 50 Mbit/s to multiple gigabits per second to a single user. [37]
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 ...
[11] [8] SES's O3b constellation was the first MEO high-throughput satellite system, launched in 2013, and by 2018 more than 18,000 new LEO satellites had been proposed to launch by 2025. [12] Despite the higher costs associated with spot beam technology, the overall cost per circuit is considerably lower as compared to shaped beam technology. [1]
Planned future satellite projects using the K a-band include Amazon's Project Kuiper satellite internet constellation in LEO, [18] SES's multi-orbit satellite internet system of the SES-17 satellite in GEO (launched in October 2021; in position and fully operational in June 2022) [19] and the O3b mPOWER constellation in MEO (first two ...
