Daily and monthly ground-based Satellite Laser Ranging observation files from the NASA Crustal Dynamics Data Information System provide millimeter-precision range measurements to satellites with retroreflectors. The data, gathered by a global network of stations, supports the International Laser Ranging Service for producing precise station positions, satellite orbits, and geophysical parameters. It is available in ILRS and Consolidated Ranging Data formats.
Data is available in two formats (older ILRS format and Consolidated Ranging Data format). License details are unclear; users should verify terms on the CDDIS website.
