# ORBCOMM receiver

> ORBCOMM receiver decodes satellite transmissions into packets and parses known packet types. Its Python scripts process recorded IQ data or live RTL-SDR input, compensate for satellite motion and report message, network and ephemeris fields. The repository includes sample recordings and DSP exercises for timing and phase recovery.
