Weather System Follow-on Microwave
The Weather System Follow-on Microwave (WSF-M) Satellite is the United States Department of Defense's next-generation operational environmental satellite system. WSF-M will be a Low Earth Orbit (LEO) satellite with a passive microwave imaging radiometer instrument and hosted furnished Energetic Charged Particle (ECP) sensor.
WSF-M will be the first satellite in the Weather System Follow-on (WSF) program. Following the cancellation of the National Polar-orbiting Operational Environmental Satellite System (NPOESS), the Air Force pursued development of a new weather satellite under the Defense Weather Satellite System (DWSS) program. However, when that system faced delays and funding issues, the White House cancelled it and instituted the WSF program.
WSF-M is designed to mitigate three high priority DOD Space-Based Environmental Monitoring (SBEM) gaps: ocean surface vector winds, tropical cyclone intensity and LEO energetic charged particles.
