  1. Development of quality control tools for the MLRO G. Bianco, V. Luceri, D. Iacovone ILRS 2008 Poznan, Poland - 13-17 October 2008

  2. One year ago… ILRS 2008 Poznan, Poland - 13-17 October 2008

  3. At that time we concluded… • A dedicated SLR system engineer is mandatory. • A set of quasi real-time SLR station health indicators should be agreed upon, defined and developed by system specialists and data analysts. This should allow to rapidly pinpoint a problem arising at a station • Is range bias monitoring enough? • Standardizing calibration procedures? ILRS 2008 Poznan, Poland - 13-17 October 2008

  4. The three souls in SLR: ILRS 2008 Poznan, Poland - 13-17 October 2008

  5. The scientist (DA) ILRS 2008 Poznan, Poland - 13-17 October 2008

  6. The engineer (EN) ILRS 2008 Poznan, Poland - 13-17 October 2008

  7. The operator (OP) ILRS 2008 Poznan, Poland - 13-17 October 2008

  8. Data acquisition Check OP nok Report to DA ok CheckDA ok Feedback to OP send data nok OP = Operators DA = Data analysts EN = Engineers Action (EN/AD/OP) Internal QC ILRS 2008 Poznan, Poland - 13-17 October 2008

  9. Internal QC • Acquisition phase • Calibration stability (mean, rms) • Pass parameters stability (editing, rms, other) • Routine checks • Diagnostics, calibrations • Other procedures in collaboration with EN ILRS 2008 Poznan, Poland - 13-17 October 2008

  10. MLRO health indicator parameters • Automatically monitored params (DA is automatically notified if threshold values are reached): • System delay rms (should be <2 mm) • System delay variations • Transmitted energy std • Pass residuals rms ILRS 2008 Poznan, Poland - 13-17 October 2008

  11. System delay ILRS 2008 Poznan, Poland - 13-17 October 2008

  12. Info from Analysis Center Check DA ok No action nok OP = Operators DA = Data analysts EN = Engineers Action (EN/DA/OP) External QC ILRS 2008 Poznan, Poland - 13-17 October 2008

  13. External QC • ILRS reports • ILRS station performance • Biases from Hitotsubashi Univ. • GeoDAF MLRO monitor ILRS 2008 Poznan, Poland - 13-17 October 2008

  19. ILRS 2008 Poznan, Poland - 13-17 October 2008

  20. ILRS 2008 Poznan, Poland - 13-17 October 2008

  21. Lesson learned, and conclusions • Improve interaction between DA, EN and OP • Web based monitor system on line and working • Better understanding of the system • Clear identification of issues • Still a lot to be done… ILRS 2008 Poznan, Poland - 13-17 October 2008
