TIROS

From Wikipedia, the free encyclopedia

TIROS, or Television Infrared Observation Satellite, was a series of early weather satellites launched by NASA, beginning with TIROS-1 in 1960. The program was successful in proving the usefulness of satellite weather observation.

TIROS continued as the ESSA TIROS Operational System, and was eventually succeeded by the NOAA ITOS (Improved TIROS Operational System), or TIROS-M, and then by the TIROS-N and Advanced TIROS-N series of satellites.
