(1/n) THREAD: Signal sessions part xyz! Thanks to @ea4gpz and @coastal8049 for nice articles about and around @cgbassa's software! So much to learn about orbital mechanics. But while I'm getting very decent results on LEO satellites, there's a mystery hanging over the equator! 
(2/n) I was curious could I see the Alphasat wobble via Doppler shift. I randomly selected a peak/carrier at 1538.029 MHz. Because of a patch antenna I really not idea where's the signal is coming from. Anything from 24E to 70E...
