These data provided means to observe vegetation, clouds, lakes, shorelines, snow, aerosols and ice. The data acquired during each scan allowed, after ground processing, multispectral analysis of hydrologic, oceanographic, land use and meteorological parameters.ĭata from channels l, 2, and 3A were used to monitor reflected energy in the visible and near-IR portions of the electromagnetic spectrum.
Science Data Processing: NOAA/CEMSCS, Air Force Global Weather Central (AFGWC), International Weather Services and ARGOSĮarth imaging was accomplished by the AVHRR/3, a six-channel scanning radiometer, which viewed the same Earth area with each channel. Science Data Capture: Tape playback direct to CDA (typically eleven 12-minute contacts per day), relayed to the NOAA/CEMSCS in Suitland, MD. Return Data Link: Housekeeping telemetry from HRPT and GAC downlinks. Forward Data Link: S-band command uplink encrypted. DSN 26-m and AFSCN for contingency support. Operation Control: NOAA/SOCC CDA stations at Wallops and Fairbanks. Propulsion: Mono propellant hydrazine, GN2 and AKM. Orbit: Sun-synchronous, 833 ± 19 km or 870 ± 19 km. Each spacecraft was designed to meet all on-orbit performance requirements for a minimum period of two years. Upon completion of testing, the satellites were turned over to NOAA for routine operational control. Upon successful achievement of orbit, NASA conducted an engineering evaluation and checkout of each satellite. The Advanced Tiros N / NOAA KLM satellites replaced operational sun-synchronous polar orbiter weather satellites on-orbit as required to provide continuity to the NOAA-managed operational system. merican earth weather satellite.ĪKA: NOAA KLM.
