RTL-SDR for 433MHz/70cm CubeSats Signal Captures

Introduction In the last two posts I looked at hardware for receiving CubeSats as well as software for decoding the signals (Ref.1/2). In this post I will put this all together for real time CubeSat signal captures. Compared to receiving NOAA15/18/19, I find CubeSat reception quite difficult. First the frequency is higher so there is… Continue reading RTL-SDR for 433MHz/70cm CubeSats Signal Captures

RTL-SDR for 433MHz/70cm CubeSats on GNURadio

Introduction In the previous post I examined receiving Amateur Radio/University CubeSats on the 433MHz/70cm band (Ref.1). In this post I look at how to decode CubeSat transmissions using the gr_satellites out of tree module on GNURadio. gr_satellites was developed by Daniel Estevez EA4GPZ. I will test several library signal captures to demonstrate how to use… Continue reading RTL-SDR for 433MHz/70cm CubeSats on GNURadio
