    • Ground-Based Global Navigation Satellite System (GNSS) IRNSS Broadcast Ephemeris Data (hourly files) from NASA CDDIS

    Metadata Updated: May 27, 2024

    This dataset consists of ground-based Global Navigation Satellite System (GNSS) Indian Regional Navigation Satellite System (IRNSS) Broadcast Ephemeris Data (hourly files) from the NASA Crustal Dynamics Data Information System (CDDIS). GNSS provide autonomous geo-spatial positioning with global coverage. GNSS data sets from ground receivers at the CDDIS consist primarily of the data from the U.S. Global Positioning System (GPS) and the Russian GLONASS. Since 2011, the CDDIS GNSS archive includes data from other GNSS (Europe’s Galileo, China’s Beidou, Japan’s Quasi-Zenith Satellite System/QZSS, the Indian Regional Navigation Satellite System/IRNSS, and worldwide Satellite Based Augmentation Systems/SBASs), which are similar to the U.S. GPS in terms of the satellite constellation, orbits, and signal structure. The hourly IRNSS broadcast ephemeris files contain one hour of IRNSS broadcast navigation data in RINEX format from a global permanent network of ground-based receivers, one file per site.
