Data Corrections

SLR stations are capable of measuring ranges very precisely and accurately, but sometimes; due to the complexity of SLR systems, biases can be induced. Engineering analysis can uncover the error sources and frequently bias problems are recoverable.

Currently data corrections are available in two formats (free format and SINEX). Data Corrections pre 1 January 1999 are in free format available from slr_problems_index.html . Data Corrections post Jan 1, 1999 are available in SINEX format (Reference SLRmail#1020).

Files have been created by the ILRS Analysis Working Group for use with SLR data; these files are are maintained by (and accessible from) DGFI on behalf of the AWG. The ILRS Discontinuities File is used to keep track of the various solution numbers and includes the information available from ITRF. The ILRS Data Handling File summarizes in a common format all information on range-, time- or pressure biases from all SLR tracking station, adopted by the ILRS Analysis Working Group. Additionally the file contains a list of stations with periods of data to be excluded from processing.
