Automated Picture Transmission (APT) Data
        APT data is smoothed 4-km (2.5-mi)-resolution IR and visible imagery derived from
        the AVHRR/3 instrument and transmitted within the footprint of the NOAA polar orbit-
        ers. Because APT data is captured on low-cost VHF ground stations, it is also very
        popular in schools. Users purchase the necessary equipment (computer, software, and
        antenna) from commercial companies for unlimited access to APT signals. In 2004,
        there were 4,945 APT receivers worldwide registered with the WMO.
        The Satellite Operations Control Center (SOCC) can select by command any two
        of the active five AVHRR/3 channels provided to the MIRP, which are further
        processed as Video A and Video B. One APT line, consisting of one line of
        Video A and one line of Video B, is output every third AVHRR scan. Ancillary
        AVHRR data appears at one edge of each line and their 64-second repetition peri-
        od defines the APT frame length. The resulting line rate is two per second. The
        data is transmitted continuously over a dedicated VHF link as an analog signal
        consisting of an amplitude-modulated 2400-Hz subcarrier frequency modulating
        the RF carrier at 137.1 MHz or 137.9125 MHz.
