Agenda for IGS AC Splinter Meeting
----------------------------------------------------
3 June 2008, 17:40 - 18:30, Ritz-Carlton Fisher Room

* AC changes

  - REMINDER: when ACs make changes, it is vital to report these, 
    preferably in advance.  In some cases, comparison of parallel
    test solutions is recommended.  Please notify both:

      sinex@geod.nrcan.gc.ca
      igs.acc@noaa.gov

* IGU changes & improvements 

  - can AC product deliveries be speeded up?
  - present delay from last data is 2h 50m
  - what is a reasonable goal?

  - is it useful to consider more frequent IGU updates?
  - how often (from present 6 times per day)?
  - note that an increase in quantity of deliveries will
    almost certainly lead to a loss of quality due to heavy
    work load; quality monitoring will be reduced
  - will have to emphasize "as is" standard (which is official
    standard now, but users have come to expect more)

  - ACC proposes to deweight USU orbit contribution to
    improve IGU orbit combination
  - what about USU clock contribution?

  - what can be done to improve EOP predictions, esp
    UT1?

* IGR changes & improvements 

  - can AC product deliveries be speeded up?
  - present AC delay is 16h; combined product delivery is 17h
  - what is a reasonable goal?

  - should USN orbit contribution be deweighted here too
    due to incompatible antenna modeling?
  - USN clocks already rejected from IGR combination

  - what can be done to improve EOP predictions, esp
    UT1?

* reprocessing issues

  - will there be reprocessed tropo products?

* naming of clock files of variable sampling intervals?

* venue for next IGS workshop
