Use of APT satellite infrared data in oceanographic survey operations



For several years, earth oriented experimental and operational satellites have been broadcasting visible and infrared terrestrial radiation data as they are collected by the satellite sensors. Some of these data broadcasts are receivable by APT (automatic picture transmission) stations located within the line of sight of the transmitting satellite. The advantage of this type of data transmission is that APT stations located anywhere in the world have immediate access to a satellite's radiation data are collected and broadcast over their local areas.
