QPSK and CCSDS Packets: Meteor‐M 2N Satellite Signal Reception

Summary

Analyzing digital satellite communication protocols is an opportunity to explore all the layers of signal routing, from the physical layer with the phase‐modulated signal we acquire to the error‐correcting mechanisms (convolutional code to be decoded using the Viterbi algorithm and Reed–Solomon block code), and finally collect data blocks containing the JPEG image thumbnails to be assembled to provide a complete picture. This whole demonstration requires, from a hardware perspective, about €10 worth of investment for finally having the satisfaction of mastering the whole communication chain as used in space links.
