Multi-Global Navigation Satellite System (GNSS) Broadcast Ephemeris Data (daily files) from NASA CDDIS
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/gnss/gnss_daily_multi_b_001
This dataset consists of ground-based multi-GNSS (Global Navigation Satellite System) Broadcast Ephemeris Data.
Description
GNSS satellites 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 GLObal NAvigation Satellite System (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. Colleagues at the Technical University in Munich (TUM) and Deutsches Zentrum für Luft- und Raumfahrt (DLR) provide to the CDDIS a merged, multi-GNSS broadcast ephemeris file containing GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS ephemerides.
