ILRS NEWG Meeting Nice 2003

Nice, France
April 8, 2003


"Old" Stuff:

  • Site Logs: Actuality / Updates, Revision 1.1
    • Laser System Section: Add Cavity Length
    • Start Pulse Detector: Add Specs
  • Global Use of Time Bias Exchange

"New" Stuff:

  • Engineering Data File (Word Format)
  • MyStationPerformance.Com
  • Data Corrections File Issues
  • New Bias Detection Capabilities / 28 Day Coords
  • Dynamic Priority Scheduling:
    • Global Use of Time Bias Exchange
    • HTSI Suggestions


  • Minimum Number of Returns per NP
    • Status: MOST Stations do NOT use this criteria;
    • It SHOULD be used, to avoid noise points, to improve data quality etc.
    • ILRS Governing board should sent 1 more notice to the stations, to implement it;
    • At the October meeting in Koetzting, this should be checked again, and - in case - some additional action started then ….
  • Global Use of Real Time Time Bias Exchange, and Time Bias Prediction File:
    • Availability: YES : just implement it, enjoy it
    • Werner Gurtner will send another notice to SLR stations, to encourage implementation
  • MyStationPerformance.Com:
    • Van Husson reported about the present status
  • New Bias Detection Capabilities / 28 Day Solutions:
    • Van Husson reported about this new possibilities;
    • Seems to be a quite powerful new technique to detect problems …
    • Needs sufficient data, and for some cases a nearby core station, but allows significantly better results
  • Engineering Data File (EDF: proposal, format, presentation)
    • Each CAL (and each pass) adds a line of parameters to the station EDF;
    • The list of parameters can be individual for each station; whatever they need and can …
    • The format has to be defined, but is not fixed; could be XML, or indexed, or …..
    • Goal: This allows for each station a complete history of hardware settings, parameters, CAL values, statistics, met values etc.etc.;
    • Expected advantages and output:
      • Each Station can (automatically) check for consistency, linearity, jumps etc.;
      • Analysis groups could easily cross-correlate any signatures;
      • Comparisons between EDF files of similar stations should identify possible improvement areas by simple comparisons ….
    • Some stations (Matera, RGO, Graz, NASA) agreed to check their possibilities, and to start with such recordings as soon as a first test format is defined; the goal is to have first results for the Koetzting meeting in October.
