Automatic Picture Transmission (APT)

Automatic Picture Transmission (APT) is a system used to transmit weather satellite images in real-time. The system uses a low-resolution camera to capture images of the Earth's surface, which are then transmitted to a ground station via radio waves. The images are then processed and displayed as weather maps. APT is used by many countries to monitor weather patterns and predict weather conditions. The system is particularly useful for tracking severe weather events such as hurricanes and typhoons.
