LEO Satellite Reception and Doppler-Shift Correction
summary
Builds an SDR around a Novena FPRF + FPGA to receive UHF LEO downlinks from ~15–20 amateur satellites, ingesting public TLEs and using Gpredict for tracking. Uses GNU Radio blocks and a contributed phase-preserving Doppler correction module; the correction is proven in software but not yet fully integrated live. A two-antenna phasing harness briefly works in the field; major obstacles are multi-day local compilations and driver gaps, so cross-compiling and cloud builds are the immediate next steps.
