Tranche 1 Tracking Layer C is one of five missions by the United States Space Force Space Development Agency (SDA) for the Proliferated Warfighter Space Architecture (PWSA) Tranche 1 Tracking Layer constellation, which will provide global indications, warning, tracking, and targeting of advanced missile threats, including hypersonic missile systems.
Polar 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 OrbitSecond Weather System Follow-on (WSF) satellite. WSF-M (Weather System Follow-on - Microwave) is the next-generation operational environmental satellite system for the Department of Defense (DoD), to replace the microwave wavelength weather forecasting capabilities of the DMSP satellites. Ball Aerospace has been selected in late November 2017 to be the prime contractor for 2 Low Earth Orbit (LEO) weather satellites with a passive microwave imaging radiometer instrument and hosted Government furnished energetic charged particle (ECP) sensor space weather payload developed by the Air Force Research Laboratory. The radiometer leverages the Ball-built Global Precipitation Measurement (GPM) Microwave Imager (GMI) instrument. This mission will improve weather forecasting over maritime regions by taking global measurements of the atmosphere and ocean surface. The launch will also include BLAZE-2, a launch opportunity for operational, research, development, and prototype small satellites from across the DoD.
