## Intro to Automatic Picture Transmission
|
|
Automatic picture transmission (APT) is an analog image transmission format
|
|
developed for use on weather satellites in the 1960s. While only three
|
|
modern satellites, NOAA 15, NOAA 18, and NOAA 19, transmit on the APT
|
|
protocol, building a reception station is cheap and simple. The images can
|
|
be quite high qualitythey natively have a resolution of
|
|
4 km/px. It is reasonable to expect at least one good-quality satellite
|
|
pass (and, thereby, opportunity for image downlink) per day.
