Satellite Laser Ranging (SLR) ILRS Orbit Prediction Product (multi-day, daily, and sub-daily files) from NASA CDDIS

**This data set is superseded by data set "Satellite Laser Ranging (SLR) Predictions" from NASA CDDIS, See doi.org/10.5067/SLR/SLR_PREDICTIONS_001** This derived product set consists of Satellite Laser Ranging Predicted Orbit Product (daily files in Consolidated Prediction Format, or CPF) from the NASA Crustal Dynamics Data Information System (CDDIS). SLR provides unambiguous range measurements to mm precision that can be aggregated over the global network to provide very accurate satellite orbits, time histories of station position and motion, and many other geophysical parameters.

SLR operates in the optical region and is the only space geodetic technique that measures unambiguous range directly. Analysis of SLR data contributes to the terrestrial reference frame, modeling of the spatial and temporal variations of the Earth's gravitational field, and monitoring of millimeter-level variations in the location of the center of mass of the total Earth system (solid Earth-atmosphere-oceans). In addition, SLR provides precise orbit determination for spaceborne radar altimeter missions.
