SINEX Data Integrity Analysis: Analysis Centers Comparison Report

This report, from the May 22-23, 2000 Analysis Center WG, evaluates data integrity in ILRS station coordinates with a focus on eccentricities and constraints. Recommendations for improvements are included.

  2. Analysis Centers Analysis WG (May 22-23, 2000)

  3. Analysis Center Report Card(SINEX Format and Data Integrity) Legend Missing block Has at least one data format/integrity issue OK # Indicates number of data integrity issues ? Potential data integrity issue Analysis WG (May 22-23, 2000)

  4. HEADER LINE Data Integrity Analysis WG (May 22-23, 2000)

  5. FILE/REFERENCE Data Integrity Analysis WG (May 22-23, 2000)

  6. SITE/ID Data Integrity Analysis WG (May 22-23, 2000)

  7. SITE/ECCENTRICITY Data Integrity(eccentricities in north, east, up) Analysis WG (May 22-23, 2000)

  8. SITE/ECCENTRICITY Data Integrity(eccentricities in XYZ) Analysis WG (May 22-23, 2000)

  9. SOLUTION EPOCH Data Integrity Analysis WG (May 22-23, 2000)

  10. SOLUTION STATISTICS Data Integrity Analysis WG (May 22-23, 2000)

  11. SOLUTION ESTIMATE Data Integrity Analysis WG (May 22-23, 2000)

  12. SOLUTION APRIORI Data Integrity Analysis WG (May 22-23, 2000)

  13. Final Remarks Improvements are needed in the management of system eccentricities. There is evidence of computer round-off, truncation, or computational errors from North, East, Up eccentricities to XYZ. Still confusion with the Zimmerwald and San Fernando system reference point. Should the constraint codes be standardized? The epoch references in the different SINEX blocks need some work. Analysis WG (May 22-23, 2000)
