The SINEX (Solution INdependent EXchange) format is a well-established format used by the technique services of the IERS for several years. Since 2001 the IERS Analysis Coordinator has been taken care of the SINEX format updates. Following the discussion at the Unified Analysis Workshop (UAW) 2009 in San Francisco the IERS Directing Board has established a Working Group on the SINEX format.
The aim of the working group is to maintain the SINEX format according to the needs of the IERS, the technique services (IDS, IGS, ILRS, IVS) and GGOS. The working group should be the point of contact if any modifications or extensions are required. In order to have the best possible interaction with the groups working with the SINEX format (either as output or as input), the analysis and combination groups of all the technique services as well as the relevant components of the IERS and GGOS are represented within the working group.
