GAC? #6

Closed zeke800 closed 2 years ago

zeke800 commented 2 years ago

Describe the feature you would like Is it possible to demodulate and decode GAC? Is it LHCP or RHCP, too?

Thanks!

Added in 8e38df2

NOAA-19 is LHCP, NOAA-18/15 are probably RHCP though. You can find out when the dumps begin with this

Just going to use this issue to ping you, but I made some improvements to the GAC demodulator since 8e38df2, so might be worth checking out.

Thank you for replying! I just saw this now :) Yes, I can confirm NOAA 18 and 15 are RHCP. Fortunately, I have a linear feed so I can receive all of them. Another interesting thing about NOAA 18 is that it does a few dumps per pass, not just one, on different frequencies, and sometimes at the same time.
