Introduction In the last five posts I have discussed receiving CubeSats under various conditions and locations. Following my successful reception of EIRSAT-1, I wanted to see if my procedure could be used for other University/Educational CubeSats (Ref.1/5). I cross referenced several data bases to make a collection of possible candidates. First, the CubeSat must be… Continue reading CubeSat Veronika on GNURadio

Introduction In the last four posts I have discussed receiving CubeSats under various conditions and locations. In Montreal I discovered a perfect receive location with no QRM, but unfortunately the VEE dipole did not have enough gain to get a proper decode. The signal was visible but not decode-able. So my method now is to… Continue reading CubeSat 437MHz on GNURadio

Présentation la semaine passée j’ai pris quelques vacances à Montréal. Comme j’aime faire de la randonnée jusqu’au mont Royal, j’ai pensé que ce serait amusant de faire un peu de radio amateur et de voir si je pouvais recevoir EIRSAT-1 que j’avais reçu auparavant à Toronto. En raison de restrictions de taille, je n’ai pas… Continue reading CubeSat 437MHz à Montréal

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
