Data Center Operations

The ILRS utilizes previously developed data flow paths to provide satellite and lunar laser ranging normal point (NP) and fullrate data and predictions to the user community. At a minimum, laser stations forward their data to operations/data centers on a daily basis where they are merged into files by day and satellite for transmission to and archive at the global data centers. Prediction Centers email their predictions to their select set of stations and the global data centers. Currently, the two ILRS global data centers make their data holdings available in different directory and file structures. These centers exchange their recently-delivered NP data at least once per day to ensure that their holdings are equalized and that users can continue to reliably access NP data should one center be unavailable.
