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

Description

This dataset consists of ground-based Global Navigation Satellite System (GNSS) Galileo Broadcast Ephemeris Data (sub-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 sub-hourly Galileo broadcast ephemeris files contain 15 minutes of Galileo broadcast navigation data in RINEX format from a global permanent network of ground-based receivers, one file 15 minutes per site. More information about these data is available on the CDDIS website at https://cddis.nasa.gov/Data_and_Derived_Products/GNSS/high-rate_data.html.
