8) What kind of images can be
received?
Automatic Picture Transmission (APT) imagery shows the earth from a height of 800 to 1600 km. Two complete images are built up side by side. One image is in the near IR (infrared) and the other is in visible light during the spacecraft's day and far IR during the spacecraft's night. Image resolution is 4 km at the suborbital point and each swath is approximately 2,700 km wide. Visible light images show geographic features and weather features. Near IR images show geographic features and additional weather features not visible in visible light. Far IR images show weather features defined by their temperature and some geographic features. APT imagery comes from polar orbit satellites such as NOAA 10 and Meteor 3-3.
