Welcome to Libgnss-Recv-Gps

An Embedded System Friendly GNSS Library Provided by Orientable.AI.

Overview

Orientable AI GNSSLib is a comprehensive software-defined radio (SDR) library designed for real-time GNSS signal processing. Written primarily in C, it provides high-performance implementations of PRN code generation, signal acquisition, tracking, and navigation message decoding.

Features

• Core Signal Processing:
  • PRN code generations (GPS L1C/A, GLONASS G1, SBAS L1)
  • High-sensitivity signal acquisition and robust tracking
  • Real-time decoding of navigation messages
  • Precision measurements: Pseudo-range, Doppler, and Carrier Phase
• Positioning Integration:
  • Real-time positioning powered by RTKLIB
  • Standardized output: RINEX or RTCM formats
• Hardware Support:
  • NSL Stereo
  • SiGe GN3S sampler v2/v3
  • Nuand BladeRF
  • RTL-SDR
• Post-Processing: Support for RF binary files for offline analysis.

Project Structure

The repository is organized as follows:

• src/: Core library source codes.
• cfg/frontend/: Front-end configuration files.
• lib/: Third-party libraries (RTKLIB, ka9q-fec, pffft).
• tests/: Integrated test data and output directories.
• bin/: Sample configuration and executables.
