Portable GNSS Software-Defined Receiver Based on ADALM-Pluto SDR

NavSync develops a low-cost, modular, and flexible GNSS receiver using an ADALM-Pluto SDR integrated with GNU Radio and GNSS-SDR. The Pluto SDR captures L1-band GPS signals and streams baseband I/Q data to a host system performing acquisition, tracking, decoding, and PVT estimation. The system targets acquisition of at least six satellites within 20 seconds and horizontal positioning error below 20 meters under open-sky conditions. Experimental validation in diverse real-world scenarios demonstrates stable real-time tracking and continuous PVT output.
