Real-time Decoding of Satellite Signals

Satellite is a common term these days and a tremendous amount of work is conducted in space and technology. The proposed system briefs about the decoding of live satellite signals with help of a mini ground station using USRPB200 Software Defined Radio (SDR), RTL SDR mini and a self-designed V-shaped Antenna. The objective of the proposed system includes decoding the satellite signals in the Ultra High Frequency(UHF) and Very High Frequency (VHF) bands with their respective implementations in the GNU Radio environment. Signals from International Space Station (ISS), Meteor Satellites, and National Oceanic and Atmospheric Administration (NOAA), are captured during multiple passes to study in detail and explore how communication exactly happens. The proposed system also sheds light on the hardware and software used while decoding the signals, the mini-ground station, the different challenges faced during the process, and the solutions to overcome the same.
