Television Infrared Observation Satellite allow integration of additional payloads. A change from the TIROS-N through NOAA-D spacecraft was that spare word locations in the low bit rate data system TIROS Information Processor (TIP) was used for special instruments such as the Earth Radiation Budget Satellite (ERBE) and SBUV/2. The search and rescue (SAR) system became independent, utilizing a special frequency for transmission of data to the ground. Television Infrared Observation Satellite TIROS, or Television Infrared Observation Satellite, is a series of early weather satellites launched by the United States, beginning with TIROS-1 in 1960. TIROS was the first satellite that was capable of remote
Weather System Follow-on Microwave 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
