NOAA-4, also known as ITOS-G was a weather satellite operated by the National Oceanic and Atmospheric Administration (NOAA). It was part of a series of satellites called ITOS, or improved TIROS.^[4] NOAA-4 was launched on a Delta rocket on 15 November 1974. The launch carried two other satellites: AMSAT-OSCAR 7 and Intasat.^[2] It remained operational for 1463 days until it was deactivated by NOAA on 18 November 1978.
