Title
Automatic Picture Transmission
Full Description
Automatic Picture Transmission (APT) enabled meteorologists to
obtain immediate local area cloud pattern photographs when the
Nimbus satellite was within a 1700-mile range of a receiving
station. The APT subsystem pioneered on Nimbus 1, which was
launched August 28, 1964, provided direct readout of nighttime and
daytime cloud coverage. It transmitted photographic data of
synoptic meteorological conditions in areas 1200nmi square to over
300 ground stations in more than 43 countries. APT was part of
three experiments performed on Nimbus 1, with the other
experiments being Advanced Vidicon Camera Subsystem (AVCS)
and High Resolution Infrared Radiometer (HRIR). This subsystem
facsimile receiver required relatively simple ground station
equipment at the price of about $30,000 per set.
