SkyRoof is an open-source Windows application that combines amateur radio satellite tracking with software-defined radio capabilities. It provides real-time satellite positions, pass predictions, and detailed information about satellites transmitting on amateur radio frequencies. Interactive sky, Earth, timeline, and pass list views help operators plan observations and communications. An SDR waterfall displays VHF and UHF satellite signals with Doppler-corrected frequency information. Built-in receivers support SSB, CW, and FM operation. Telemetry decoders process several digital modulation formats and can submit frames to SatNOGS. Image decoders reconstruct SSTV and SSDV transmissions. Additional tools support FT4 contacts, QSO logging, audio recording, transceiver control, and antenna rotators.
