Development of Quality Control Tools for the MLRO-ILRS 2008 Poznan Conference

This paper discusses the development of quality control tools for the MLRO-ILRS conference held in Poznan, Poland in October 2008. The paper highlights the importance of a dedicated SLR system engineer and the need for quasi real-time SLR station health indicators. It also explores the role of the scientist, engineer, and operator in SLR data acquisition and checks. The paper presents internal and external quality control measures, including monitored parameters and external QC reports. The lessons learned and conclusions from the conference are also discussed.

  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

  14. 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
