Satellite Constellations - 2021 Industry Survey and Trends
[SSC21-XII-10] Satellite Constellations - 2021 Industry Survey and Trends Erik Kulu NewSpace Index, Nanosats Database, Kepler Communications [email protected] ABSTRACT Large satellite constellations are becoming reality. Starlink has launched over 1600 spacecraft in 2 years since the launch of the first batch, Planet has launched over 450, OneWeb more than 200, and counting. Every month new constellation projects are announced, some for novel applications. First part of the paper focuses on the industry survey of 251 commercial satellite constellations. Statistical overview of applications, form factors, statuses, manufacturers, founding years is presented including early stage and cancelled projects. Large number of commercial entities have launched at least one demonstrator satellite, but operational constellations have been much slower to follow. One reason could be that funding is commonly raised in stages and the sustainability of most business models remains to be proven. Second half of the paper examines constellations by selected applications and discusses trends in appli- cations, satellite masses, orbits and manufacturers over the past 5 years. Earliest applications challenged by NewSpace were AIS, Earth Observation, Internet of Things (IoT) and Broadband Internet. Recent years have seen diversification into majority of applications that have been planned or performed by governmental or military satellites, and beyond.

There were much fewer Earth Observation com- NewSpace Index has tracked commercial satellite panies in 1990s and 2000s when compared to com- constellations since 2016.

PRESS RELEASE SES Q1 OPERATING PROFIT UP 6.7% REVENUE UP 4.2% Luxembourg, 12 May 2011 – SES S.A. (Euronext Paris and Luxembourg Stock Exchange: SESG) reports financial results for the three months to 31 March 2011. FINANCIAL HIGHLIGHTS • Revenue of EUR 428.4 million (+4.2 %) Recurring1 revenue grew 3.1% to EUR 428.4 million • EBITDA of EUR 321.5 million (+3.5%) Recurring EBITDA grew 3.0% to EUR 323.8 million Recurring EBITDA margin of 75.6% • Operating profit of EUR 206.3 million (+6.7%) • Profit of the group of EUR 149.4 million (+40.1%) • Earnings per A-share rose 40.7% to EUR 0.38 (2010: EUR 0.27) • Closing net debt / EBITDA of 2.80 times Romain Bausch, President and CEO, commented: “SES’ financial results are on track, reflecting business developments in the first quarter. A number of contracts were signed for new Direct-To-Home (DTH) and broadband services in Europe, and the development of HD programming in Germany was given a boost as the German public broadcasters committed to five transponders to follow the termination of analogue broadcasting in April 2012. New capacity agreements for broadcast and broadband services in Central and Latin America were signed, and additional capacity was contracted for global maritime services. Following the commercialisation of all available DTH capacity for India, we have ordered a new satellite, SES-8, to provide additional capacity for that fast- growing market. SES has reorganised its activities under a streamlined management structure, which will optimise the execution of our growth strategy. -

THAICOM 8 Set to Launch in 2016 to Support Thailand’S Growing Broadcasting Industry, and Serve the Asia and Africa Markets
THAICOM 8 Set to Launch in 2016 To support Thailand’s growing broadcasting industry, And serve the Asia and Africa Markets Nonthaburi, 29 April 2014: Thaicom Public Company Limited, Thailand’s satellite operator, announced today that its planned Thaicom 8 satellite will be launched in the first half of 2016. This new satellite will support the growth of the country’s broadcasting industry and strengthen its competitiveness in the international market. Suphajee Suthumpun, Chairman of the Executive Committee and CEO, Thaicom Public Company Limited said that, “the Company has been preparing the ground work for the Thaicom 8 satellite, including the investment plan, technical design, project feasibility, pre-marketing, as well as, the ITU process to secure the additional frequency rights for Thailand at the 78.5 degrees East orbital slot. Now that the Company has been awarded a license for Thaicom 8 by the National Broadcasting and Telecommunications Commission (NBTC), we can proceed, and we expect to launch Thaicom 8 within the first half of 2016. THAICOM 8 will support the growth of Thailand’s broadcasting industry and provide adequate capacity to serve the HDTV trend. The satellite will also allow us to meet the Ultra-HD demands for Thailand and the international market expected in the future.” Thaicom 8 will expand Thaicom’s existing fleet of Thaicom 5 and 6 positioned at the 78.5 degrees East orbital slot, while Thaicom 7, to be launched in mid-2014, will be positioned at 120 degrees East. The Company’s Thaicom 4 (IPSTAR) broadband satellite is located at the 119.5 degrees East orbital slot and provides broadband and backhaul services to 13 countries throughout the Asia Pacific region.
