IAA VLBI Analysis Center

Data files used in analysis (supported by the IAA except other stated)

• Station info (in format adopted to SINEX SITE/ID block)
• Database name-Experiment code cross-reference table (based on the IVS master files, updated with every new session)
• Average meteo parameters for stations (based on information from databases, updated with every new session)
• Mean Pole coordinates (with prediction, updated daily)

Observations Statistics (updated near-daily)

This statistics is based on the IAA data base of NGS cards. NGS cards are created at the IAA using the software developed by Igor Surkis and Zinovy Malkin. Windows executable can be found here. Original databases are obtained from the IVS archive. Starting from June 2004 IAA AC regularly submits NGS cards to the IVS with a delay of several hours after appearing of the database in the IVS archive.

• Sessions statistics (sessstat.zip, ~3 MB)
• Global statistics (globstat.zip, ~200 KB)
• Station/date statistics (sobsstat.zip, ~75 KB)
• Problems (duplicate observations, mixed baselines, absent or suspicious meteo data, etc.) (problems.zip, ~60 KB)

Results of analysis

• EOP series are regularly submitted to the IERS and IVS, and also are available at the IAA EOP Service page.
• Session SINEX files are regularly submitted to the IVS for combination.
• Session tropospheric paremeters are regularly submitted to the IVS troposphere combining center
