The Total and Spectral Solar Irradiance Sensor 2 (TSIS-2) is a satellite designed by NASA to measure the Sun's energy input to Earth. TSIS-2 comprises two instruments, the Total Irradiance Monitor (TIM), and the spectral Irradiance Monitor (SIM). TIM measures total brightness and SIM measures spectral irradiance over a wavelength range that includes 96% of the energy in the solar spectrum. Both instruments are similar to those used for the TSIS-1 mission onboard the International Space Station.
Sun-Synchronous Orbit3.7-ton South Korean geostationary communications satellite also known as Chollian-3. Designed to replace GEO-Kompsat-1 launched in 2010, it features advanced payloads for communications, disaster prevention, maritime safety and the safe flight of aircraft
Geostationary Transfer OrbitThe JPSS constellation of satellites collects global multi-spectral radiometry and other specialized meteorologic, oceanographic, and solar-geophysical data via remote sensing of land, sea, and atmospheric properties. These data support NOAA’s mission for continuous observation of Earth’s environment to understand and predict changes in weather, climate, oceans, and coasts to support the nation’s economy and protect lives and property. NASA uses the instruments aboard the JPSS satellites to continue decades of Earth science research for the betterment of humanity. JPSS-4 carries the NASA Earth Venture mission Libera, an instrument to improve our understanding of trends in Earth’s energy imbalance and our changing climate.
Sun-Synchronous OrbitNASA's Near-Earth Object (NEO) Surveyor mission is designed to help advance planetary defense efforts to discover and characterize most of the potentially hazardous asteroids and comets that come within 30 million miles of Earth’s orbit. These are collectively known as near-earth objects, or NEOs. NEO Surveyor consists of a single scientific instrument: a 50 centimeter (nearly 20 inch) diameter telescope that operates in two heat-sensing infrared wavelengths. It will be capable of detecting both bright and dark asteroids, which are the most difficult type to find.
Heliocentric L1JSAT-31 is a geostationary communication satellite for SKY Perfect JSAT. Operating both in Ka and Ku frequency bands, the JSAT-31 High Throughput Satellite will offer high speed broadband services over Japan, South-East Asia, Australia, New Zealand and Pacific islands. JSAT-31 will have the largest capacity in the history of SKY Perfect JSAT satellites. It will rely on Space INSPIRE, a highly flexible and fully software-defined solution that offers instant in-orbit adjustment to broadband connectivity demand, while maximizing the effective use of the satellite resources. SKY Perfect JSAT will leverage the satellite’s extreme flexibility to offer enhanced communications services all along JSAT-31’s lifespan in orbit.
Geostationary Transfer OrbitEchoStar 26 is a direct broadcast satellite, built on the proven Maxar 1300 series platform, which will deliver content across DISH TV customers across all 50 U.S. states & Puerto Rico. It will be equipped with a high-power, multi-spot beam payload, allowing DISH to provide high-quality content to its customers.
Geostationary Transfer OrbitKPS-1 is South Korea's first navigation satellite, the 1st of 8 satellites planned for the Korean Positioning System (KPS). This will be one of 5 satellites to be deployed into an Inclined Geosynchronous Orbit (IGSO), with the other 3 in geostationary orbits. The KPS is scheduled to be completed by 2035.
