Observation 456074: NOAA 15 (25338)


#1

Regarding Observation 456074

Old subject I believe.
If using the same setup but in SDR# I get perfect clear images and the signal is very strong.
I tried moving the RF gain and so far improved a bit but clearly not enough. It’s set around 30 for now and I fear any further will overload it.
The only difference is the RTL AGC option in SDR#, which I know SatNOGS doesn’t support for now.

Couldn’t there also be difference in the satellite elevation during the pass? This one is rather low with max ele 16 degrees.


#3

I’ve taken clear shots on low 10 degree and lower elevation passes. I believe the AGC makes a difference, than can be compensated setting ng a static gain, but the bandwidth plays a role. If one could narrow the bandwidth to only where the signal is the picture will become clearer, as wide adds extra noise.
