Other Designations: Improved TIROS Operational System. Class: Earth. Type: Weather. Nation: United States. Agency: ESSA, NASA, GSFC, NOAA. Manufacturer: RCA.

ITOS was the follow-on to the TIROS series of polar-orbiting US weather satellites, and marked the beginning of the use of the NOAA designator. The program was initially managed by the ESSA (Environmental Science Services Administration). NOAA later became the managing organisation. Spacecraft: 3-axis stabilised. Two deployed solar panels. NiCd batteries. Payload: AVCS (Advanced Vidicon Camera System). APT (Automatic Picture Transmission system). FPR (Flat Plate Radiometer). SPM (Solar Proton Monitor). VTPR (Vertical Temperature Profile Radiometer). VHRR (Very High Resolution Radiometer). ITOS-1, ITOS-A, ITOS-B carried AVCS, APT, FPR, SPM. ITOS-D, ITOS-E, ITOS-F, ITOS-G, ITOS-H carried FPR, SPM, VTPR, VHRR.
