Doppler-corrected IQ signals from MRC-100 satellite

 The MRC-100 satellite, a 3PQ PocketQube developed by the Budapest University of Technology and Economics, was launched in 2023. It primarily operates in the 70 cm amateur radio band. The dataset comprises complex 32-bit floating-point samples recorded at a sampling frequency of 50 kSamples per second. Doppler correction was performed using calculations from Gpredict with Celestrak's Keplerian equations. The recordings span the period from October 21, 2023, to November 12, 2023, and were captured in Szeged, Hungary. Validation of the dataset was carried out using the recommended demodulation software, SmogCLI2. Two channels (_cha and _chb file suffixes) are included, representing different coherently sampled, linear polarizations. The date in each filename corresponds to the local time when the recording began.  This dataset serves as a valuable resource for researchers and developers aiming to test and compare demodulation techniques for amateur satellite communications.
