The Yaogan 30-01-01 to 30-01-03 (Remote Sensing Satellite-30-01-01 to 30-01-03) satellites, were launched by CZ-2C rocket from China's Xichang space center on 29 September 2017. The purpose is not confirmed, although the news reports hint towards a SIGINT mission, especially to detect ships by their radio emissions. They are also known as CX 5 by the manufacturer. The satellites are spaced by 120° in their orbit.
Low Earth OrbitA batch of 34 satellites for the OneWeb satellite constellation, which is intended to provide global Internet broadband service for individual consumers. The constellation is planned to have around 648 microsatellites (of which 60 are spares), around 150 kg each, operating in Ku-band from low Earth orbit. Eventually it can be expanded to include extra 1260 satellites, for a total of 1908.
Polar OrbitGlonass-M, also known as Uragan-M, are the second generation of Uragan satellite design used for GLONASS satellite navigation system. GLONASS is a Russian space-based navigation system comparable to the similar GPS and Galileo systems. This generation improves on accuracy, power consumption and design life. Each satellite weighs 1415 kg, is equipped with 12 L-band antennas, and has an operational lifetime of 7 years.
Medium Earth OrbitThis is the first flight of the Long March 7A which is a new configuration of the Long March 7 launch vehicle. The difference is that 7A variant includes an additional third stage, allowing the rocket to perform GTO launches. This is also the first mission out of Wenchang cosmodrome in 2020.
Geosynchronous Transfer OrbitThis satellite is a part of the geostationary component of the 3rd phase of the Chinese Beidou (Compass) satellite navigation system. It features a phased array antenna for navigation signals and a laser retroreflector and additionally deployable S/L-band and C-band antennas.
Geostationary Transfer OrbitSpaceX launched the Dragon spacecraft on their 20th operational cargo delivery mission to the International Space Station. The flight was conducted under the Commercial Resupply Services contract with NASA.
Low Earth Orbit B1059 - Flight Proven ( ) Landing Zone 1JCSAT-17 is a Japanese communication satellite of SKY Perfect JSAT Corporation. Its payloads incorporate S-band, C-band and Ku-band transponders, which will provide satellite communication services. The S-band and C-band transponders will serve NTT DOCOMO, Inc., the largest telecommunications company in Japan, for its flexible mobile communications services in Japan and the surrounding region under IRU contract (Indefeasible Right of Use). SKY Perfect JSAT will support NTT DOCOMO’s satellite communication services. JCSAT-17 also includes a flexible processor that will allow SJC to redirect capacity to concentrate on disaster relief efforts or other high-volume events. The GEO-KOMPSAT-2 program is a national program of the Korean government to develop and operate two civilian geostationary satellites sharing the same satellite bus: GEO-KOMPSAT-2A for meteorological and space weather monitoring missions; and GEO-KOMPSAT-2B for Earth environment monitoring and ocean monitoring missions. The GEO-KOMPSAT 2 program also ensures the succession for the COMS program (Communication, Ocean and Meteorological Satellite). The satellite carries two main payloads: GOCI II (Geostationary Ocean Color Imager II), provided by Airbus Defence and Space; and the GEMS (Geostationary Environment Monitoring Spectrometer), provided by Ball Aerospace & Technologies.
