Identify a good satellite passĪs with ISS, higher elevation passes tend to be longer and have a better signal, but there is some advantage to lower angle passes. Capture I/Q and audio signal during satellite pass as a backup.Set up WXtoIMG to receive audio via VAC.Set up the SDR (including I/Q recording) and pipe the audio via the VAC.There are a number of steps that I followed: Again, using a Virtual Audio Cable to pipe the received audio from SDR Console to the APT decoding software. Includes satellite tracking capability and doppler compensationĪ straightforward setup reusing a lot of what I'd learned / used for ISS SSTV capture. Vertically mounted in a tree in the back garden The kit list is pretty similar to that for capturing SSTV from ISS, but I did make a QFH Antenna tuned to 137 MHz to improve reception Serial Specifically, there are three satellites: There are a number of NOAA satellites that transmit pictures in a format called Automatic Picture Transmission ( APT). There are a lot of satellites orbiting Earth, some are communication satellites, some are imagery satellites, and some of those imagery satellites produce images that an amateur can capture and decode. Capture I/Q and audio signals during satellite pass as a backupĬan I decode weather imagery on my home made antenna? Weather Satellites.
