Image: SpaceX via SES<\/figcaption><\/figure>\n<h4>Overcoming power issues<\/h4>\n<p>SES began work on the O3b mPOWER satellites in partnership with manufacturer, Boeing, in 2017 when it ordered the construction of seven initial medium Earth orbit (MEO) satellites. It began signing up customers for the on orbit broadband service in 2020 with the likes of Carnival Corporation for its cruise ships and Orange, which supports internet service in Africa.<\/p>\n<p>The first two O3b mPOWER satellites were launched in 2022 and were followed by two more pairs of satellites in 2023. SES began providing service through the satellites in spring 2024.<\/p>\n<p>\u201cWe are very excited that O3b mPOWER is now ready to serve our customers around the world. Over the last few years, our SES team, along with our technology partners across space and ground segments, have worked tirelessly to bring our O3b mPOWER system online,\u201d said Adel Al-Saleh, CEO of SES, in an April 2024 statement. \u201cI\u2019m proud to say that all the core infrastructure is deployed, tested and ready on a global basis.\u201d<\/p>\n<p>However the first O3b mPOWER satellites ran into electrical problems. Ahead of the launch of the third pair of satellites in November, SES told investors that it documented \u201can increased number of sporadic power module switch offs\u201d within satellites 1-4, which resulted in \u201ca few non-recoverable events.<\/p>\n<p>\u201cAfter a comprehensive investigation where the causes were identified by Boeing and SES, mitigations for these events will be put in place for the initial satellites that include updated operational procedures and leveraging elements of the constellation in a resilient configuration, which will enable the expected high-performance services to customers,\u201d SES wrote in a YTD 2023 financial statement. \u201cWith the operations of this initial O3b mPOWER constellation, in combination with the existing O3b MEO constellation, SES expects it can support its currently signed O3b mPOWER customers, as well as future customers and market growth.\u201d<\/p>\n<p>The power issues were determined to cause those satellites to experience operational life that \u201cwill be significantly lower than previously expected.\u201d A plan was developed to replace the faulty power modules on the remaining satellites left on the contract at the time (7-11) and to add two additional satellites to the constellation.<\/p>\n<p>SES currently plans to deploy 13 O3b mPOWER satellites, with satellites 9-11 set to launch in 2025 and the final pair in 2026.<\/p>\n<p>\u201cThe total amount of remaining U.S. C-band clearing cost reimbursements expected to be received in future is now approximately $150 million and SES is continuing to engage with insurers regarding the claim of $472 million relating to O3b mPOWER satellites 1-4,\u201d SES wrote in a statement covering YTD and Q3 2024 financial results.<\/p>\n<p>The company said that as of April 2024, it said its second-generation MEO constellation was supporting \u201cmore than 15 million end users\u201d.<\/p>\n<p>The satellites orbit approximately 8,000 km (4,971 mi) above the Earth\u2019s surface at an inclination of 70 degrees.<\/p>\n<figure id=\"attachment_68240\" aria-describedby=\"caption-attachment-68240\" style=\"width: 876px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-68240\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/12\/20241217_O3b_mPOWER_mission_patch_small.jpg\" alt=\"\" width=\"876\" height=\"981\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/12\/20241217_O3b_mPOWER_mission_patch_small.jpg 876w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/12\/20241217_O3b_mPOWER_mission_patch_small-268x300.jpg 268w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/12\/20241217_O3b_mPOWER_mission_patch_small-678x759.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/12\/20241217_O3b_mPOWER_mission_patch_small-768x860.jpg 768w\" sizes=\"auto, (max-width: 876px) 100vw, 876px\"\/><figcaption id=\"caption-attachment-68240\" class=\"wp-caption-text\">SpaceX\u2019s design for the O3b mPOWER launches on behalf of SES.
