Global Navigation Satellite System (GNSS) Final Orbit Products from NASA CDDIS
Listed in NASA Earthdata CMR
Precise satellite orbits derived from analysis of Global Navigation Satellite System (GNSS) data.
Description
Analysis Centers (ACs) of the International GNSS Service (IGS) retrieve GNSS data on regular schedules to produce precise orbits identifying the position and velocity of the GNSS satellites. These orbits are determined sub-daily (ultra-rapid generation), daily (rapid generation), and weekly (final IGS product).
The IGS Analysis Center Coordinator retrieves these individual solutions and generates the official IGS combined orbit products. The orbits generated by the individual ACs and the combination products generated by the ACCs are available at the CDDIS. These orbits can be used to determine precise coordinates of the observing stations, gravity field parameters, and Earth orientation parameters.

The IGS Final products are the basis for the IGS reference frame and are intended for those applications demanding high consistency and quality.
