Pocket SDR is an open-source GNSS (Global Navigation Satellite System) receiver based on SDR (software defined radio) technology. It consists of a RF front-end device, some utilities for the device and GNSS-SDR APs (application programs) written in Python and C. It supports almost all signals for GPS, GLONASS, Galileo, QZSS, BeiDou, NavIC and SBAS.
From Tomoji Takasu, the author of rtklib.
