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.

We would also request that users acknowledge the information resources of the ILRS (e.g. the ILRS data centers) with the following citation, if users access ILRS data or products from the NASA CDDIS or the EDC. Please reference the following citation:

Noll, C.E., Ricklefs, R., Horvath, J. et al. (2019). "Information resources supporting scientific research for the international laser ranging service". Journal of Geodesy, 93, 2211–2225. DOI:10.1007/s00190-018-1207-2

Furthermore, please include SLR as a keyword in your papers. The SLR community relies on these acknowledgments and references to strengthen its requests for continued support from its funding organizations. The Central Bureau asks that you provide a link to and/or bibliographic reference of any SLR/LLR-related papers or presentations.
