Crustal Dynamics Data Information System (CDDIS)
Crustal Dynamics Data Information System
The CDDIS is NASA’s data archive and information service supporting the international space geodesy community. CDDIS provides continuous, long term, public access to the data and derived products from a global network of observing stations equipped with one or more of the following measurement techniques:
- GNSS-Global Navigation Satellite System (GNSS),
- Satellite Laser Ranging (SLR),
- Lunar Laser Ranging (LLR),
- Very Long Baseline Interferometry (VLBI), and
- Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS)
CDDIS also provides products derived from these data required for a variety of science observations, including the determination of a global terrestrial reference frame and geodetic studies in plate tectonics, earthquake displacements, volcano monitoring, Earth orientation, and atmospheric angular momentum, among others.
Users can access the data and products available through the CDDIS via anonymous FTP.
