IGS Status Report, July 24, 1992
________________________________

General Remarks :

 - The IGS campaign 1992 started five weeks ago.

 - The data flow is well established now. It is problematic
   that that the file-name conventions and the station name conventions
   are not always observed.

 - Regular analyses are produced by (a) CSR, Austin, (b) JPL, Pasadena,
   (c) SIO , San Diego, (d) CODE, Berne. First results  came in
   from GFZ, Potsdam and from ESOC, Darmstadt.

 - Two earth rotation bulletins were issued so far, Dennis McCarthy is
   comparing the earth rotation parameters regularly with the IERS
   evaluations. The results are encouraging, reports are given at
   weekly intervals in the IGS mailbox.

 - In summary: The experiment is running surprisingly well, Epoch'92
   campaign (25 July 0:00 UT - 8 August 23:59:59 UT) will not suffer
   from a lack of high quality orbits.

(1) IAG-Symposium 112 in Potsdam , 5 - 10  October 1992
    ___________________________________________________

 - There will be a session on IGS at the Potsdam Symposium on "Geodesy
   and Physics of the Earth".

(2) Campaign Oversight Committee Meeting, 15/16 October 1992
    ________________________________________________________

 - As announced earlier the next IGS campaign oversight committee
   meeting will take place at the Goddard space flight center (after
   the DOSE Working Group Meeting).

 - The meeting will have the form of a workshop.  We hope to see the
   members of the oversight committee and many participants of the 1992
   IGS experiments at the workshop.  We will start on Thursday, 15 October
   (probably mid-afternoon), and continue on Friday for the entire day.
   The agenda will follow.

 - Those of you having received the first announcement of the DOSE
   meeting have seen that IGS is scheduled as one of the topics of the
   DOSE meeting. Greenbelt seems to be worth a trip in October -- if
   you are interested in IGS.

(3) Suggested Post Campaign Meeting in Spring 1992
    ______________________________________________

 - There will be the need for a Post Campaign Workshop (covering the
   1992 IGS campaign AND Epoch'92) in spring 1992. I suggest to
   organize this workshop at the University of Berne (which would
   allow us not to travel too far) in the week of 22 - 26 March, 1993.

 - Since there will be a meeting on differential GPS in Amsterdam
   during the next week, the suggested time frame would allow Non -
   Europeans to optimize their trip to Europe.

 - If the idea of a meeting in Berne seems acceptable, we should be
   able to continue our planning by the end of August. Could I
   therefore have your reactions until August 21 ?

                                                    Kind regards

                                                   Gerhard Beutler

INFORMATIONS TO PRODUCT GENERATION

  The calculation of the 7-day ephemerides file is described below.

            Day of GPS Week 650        [Day 0=Sunday; Day 6=Saturday]
  Arc No.   0   1   2   3   4   5   6

       6                             XXXX----

   XXXX : The first day of the 2-day arc is used for ephemeris
          dissemination
   ---- : The second day is used for quality control by overlap

   The pole coordinates are estimated for three epochs (beginning
   of each day) with the 2-day arc's. Using the above described 
   method (one day overlaps) there are three solutions for each
   pole parameter. The submitted ERP-results are the mean values
   of these different solutions.

   cross- and along-track component are presented.

     Permanent tidal correction: None

5. Adjusted parameters:
   (a) Double-difference data

+0.001 m for horiziontal and +-0.005 m for the height were used.
   (f) X and Y pole position once per day.  (No estimate is made of UT1-
AT since these deviations are absorbed into the orbital parameters).

NOTES:
 (a) Those sites without a DOMES point number are at unknown locations,
and those sites with a (?) in the Alternate descriptions possibly have
an incorrect DOMES number.
 (b) The epoch refers to the epoch at which the site position applies
and not the mid-point of the data span.  We have also added the
velocities adopted for these sites at the end of each line.  For most sites
these are the NUVEL-1 velocities with the North American AM0-2 velocity
added.  For PIN1 and DS10, Observed velocities (based on a combined VLBI/
GPS solution using ~10 years of data have been used).
 (c) The PE notation in the site name (PINB, DS1B and JPLB) denotes 
post-Landers earthquake position (applicable after 11:58 UTC June 28, 1992.
 (d) These coordinates were estimated from the first 29 days of IGS data.
They have been rotated and translated into the ITRF 1990 frame by use
of the horizontal coordinates at YELL_GPS, PIN1_GPS, SIO1_GPS, FAIR_GPS, 
USUD_GPS, DS10_GPS, DS60_GPS, YAR1_GPS, ONSA_GPS, WTZ1_GPS, TROM_GPS, 
KOSG_GPS.  The rms difference between the horizontal coordinates of 
these sites and our previous realization (first IERS submission) was
15 mm).
