Arianespace’s Ariane 5 soars to success with JCSAT-17 and GEO-KOMPSAT-2BFebruary 18, 2020
Lifting off from the Spaceport in French Guiana, today’s flight delivered an estimated payload lift performance of 10,109 kg. JCSAT-17 was released first, separating from Ariane 5 at 27 minutes after liftoff; followed four minutes later by its GEO-KOMPSAT-2B co-passenger.https://www.arianespace.com/mission-update/va252-ariane-5-success/Japanese communications satellite and South Korean weather satellite launch on Ariane 5by Caleb Henry — February 18, 2020

An Ariane 5 rocket lifted off at 5:18 p.m. Eastern from the Guiana Space Center in Kourou, French Guiana with Sky Perfect JSAT’s JCSAT-17 satellite and the South Korean space agency KARI’s GEO-KOMPSAT-2B satellite.
Sky Perfect JSAT fleet grows to 20 satellitesJCSAT-17, the heavier of the two satellites, separated from the rocket’s upper stage approximately 28 minutes after liftoff. The 5,900-kilogram satellite from manufacturer Lockheed Martin carries C- and Ku-band transponders, and an 18-meter S-band reflector from L3Harris Technologies.
Sky Perfect JSAT now operates 19 geostationary communications satellites and SDS-4, an experimental ship-tracking smallsat in low Earth orbit satellite that it inherited from the Japan Aerospace Exploration Agency.
Sky Perfect JSAT will use JCSAT-17 to provide connectivity for Japanese telecommunications company NTT DOCOMO in C- and S-band, and other customers in Ku-band.
KARI completes environmental satellite pair KARI’s GEO-KOMPSAT-2B satellite separated 31 minutes after liftoff. The 3,400-kilogram satellite carries an ocean imaging payload from Airbus Defence and Space and an environmental spectrometer from Ball Aerospace.
KARI built the satellite to monitor air pollution and marine conditions around the Korean Peninsula. It is the second in a two-satellite environmental program, following GEO-KOMPSAT-2A, which monitors meteorological and space weather, and launched on an Ariane 5 in December 2018.
Byung-Seon Jeong, the vice minister of South Korea’s ministry of science and information and communications technology, said GEO-KOMPSAT-2B took seven years to complete. (...)

Credit: Lockheed MartinAfter extending their power-generation solar arrays, the JCSAT 17 and GEO-Kompsat 2B satellites will use their own thrusters to reshape their orbits to reach a circular geostationary perch more than 22,000 miles (nearly 36,000 kilometers) above Earth. The maneuvers will also reduce the satellites’ orbital inclination from 6 degrees to 0 degrees to take position over the equator.
The JCSAT 17 spacecraft was built by Lockheed Martin near Denver and weighed 12,912 pounds (5,857 kilograms) fully fueled for launch.
JCSAT 17 is owned by Sky Perfect JSAT, a Tokyo-based company. Once in orbit, the new satellite will unfurl a 59-foot-diameter (18-meter) S-band mesh communications antenna made by L3Harris Technologies, formerly known as Harris Corp., of Melbourne, Florida.
“I just wan to say say how proud we are at Lockheed Martin to be able to deliver one of the largest and most technologically advanced satellites to our customer,” said Guy Beutelschies, vice president of communication satellite solutions at Lockheed Martin.
“We look forward to going through initial acquisition, deploying our solar arrays, moving our satellite out into its orbital position, deploying the very large 18-meter Harris reflector, and then doing all our payload checkout so that we may turn the satellite over JSAT, so that it may serve you and your customers and the people of Japan for many, many, many years to come,” Beutelschies said in remarks after Tuesday’s launch.
JCSAT 17 carries S-band, C-band and Ku-band transponders to provide data connectivity and broadcast services over Japan and other parts of the Asia-Pacific region.
The S-band and C-band payloads on JCSAT 17 will be used by NTT Docomo, a Japanese mobile phone company, to provide mobile connectivity across Japan and surrounding regions, according to Sky Perfect JSAT.
“It will take a couple of months — maybe a month — for us to make the satellite in service,” said Eiichi Yonekura, president and CEO of Sky Perfect JSAT. “So we have to continue concentrating on taking the necessary further procedures until the mission is completed.
“Having said that, I’d like to celebrate together with you tonight our successful launch,” Yonekura said. “Including this JCSAT 17 (satellite), we are going to have to have 20 satellites in operation.”
JCSAT 17 will operate from a position along the equator at 136 degrees east longitude. The spacecraft is designed to operate at least 15 years, but it carries enough propellant to function more than 21 years, according to Lockheed Martin.
Based on the LM 2100 satellite bus, JCSAT 17 carries solar arrays designed to roll out like a window shade. Solar panels on satellites are traditionally designed to unfurl like an accordion.
The new solar array design is lighter and takes up less volume, while capable of generating more power for the satellite once in orbit. The solar arrays on JCSAT 17 will produce more than 10 kilowatts of power, including 6.5 kilowatts dedicated to the satellite’s communications payload.

The spacecraft hosts two sensors: An ocean color imager made by Airbus in Europe and a spectrometer from Ball Aerospace in Colorado. The satellite platform itself was manufactured in South Korea.
The GEO-Kompsat 2B satellite is designed to operate at least 10 years, collecting information on marine environments around the Korean Peninsula, fishery ecosystems, aerosol transport in the atmosphere, and air quality over Korea.
Byung-Seon Jeong, South Korea’s vice minister of science and information and communication technology, said the GEO-Kompsat 2B mission has been in development since 2011.
“We believe that GEO-Kompsat 2B will be an invaluable asset serving various environmental issues of humankind, especially addressing particulate matter in East Asia,” he said. “The air and ocean environmental data from GEO-Kompsat 2B is expected to significantly help many people (with) breathing concerns and minimize the damage from marine disasters.
“The government and related agencies are fully prepared to utilize the data from the satellite so that people can actually feel tangible progress,” he said. That would be the best way to make a return from all the support and trust we received from the people of our country. I’m very pleased that the successful launch of GEO-Kompsat 2B has proved Korea as one of the top space technology countries, and furthers the confidence and pride of our people.”
The Geostationary Environment Monitoring Spectrometer instrument built by Ball Aerospace is billed as the first air quality sensor in geostationary orbit. The spectrometer will take hourly measurements of air pollution, including ozone and nitrogen dioxide, to improve early warnings for potentially dangerous pollution events, according to Ball Aerospace.
“GEMS is a result of more than 30 years of innovation in advanced spectrometers at Ball Aerospace,” said Makenzie Lystrup, vice president and general manager of civil space programs at Ball Aerospace. “Data from GEMS will enable KARI’s mission to assess and forecast air pollution by identifying sources and distribution of pollutants in the atmosphere.”The GEO-Kompsat 2B mission follows the launch of GEO-Kompsat 2A on an Ariane 5 rocket in 2018. While GEO-Kompsat 2B is focused on observing the oceans and air quality, the GEO-Kompsat 2A spacecraft is a dedicated weather satellite providing information to South Korean forecasters.
