Data Centers

Currently, ILRS data centers archive SLR and LLR data (normal points and full-rate), predictions, and products derived from these data (e.g., site positions and velocities).

These data and products are available through anonymous ftp or the web from the global data centers CDDIS and EDC. Below is a table of these data centers along with accessibility information.
