I'm new to dealing with SDR. My goal is to get images from NOAA or Meteor m2 satellites. I use Wxtoimg to find the passing time of NOAA satellites and it is generally correct. But whenever I look at orbitron or gpredict, neither of them have a matching passing time. I can use wxtoimg for NOAA, but where can I find the most accurate transit information for the meteor m2 satellite's transit time?
