         --------------------

1. Analysis Center: Scripps Institute of Oceanography
2. Solution Identifier: Preliminary Submission 920624
3. Software used: GAMIT/GLOBK
4. Definition of Terrestrial Reference Frame:
     Origin: Nominally ITRF-90
     Orientation: Nominally ITRF-90
     Reference epoch: 1992.51  (MJD 48808.5)
     Relativity Scale: Terrestrial
     Velocity of light: 299792458.0 m/sec
     Permanent tidal correction: None

5. Adjusted parameters:
   (a) Double-difference data
   (b) Single day orbit arcs, 6 ICs and 3 radiation parameters per 
satellite-per-day
   (c) One-per-day-per-station zenith tropospheric parameter,
   (d) Bias parameters, one for each independent double difference 
combination.
   (e) Station positions with +- 10 m constraints at stations other 
than: ALGO, YELL, PIN1, PINB, JPL1, JPLB, SIO1, SIO2, FAIR, KOKR, 
USUD, DS10, DS1B, DS40, DS41, DS60, YAR1, MCMU, TAIW, ONSA, WTZ1, 
METS, MATE, TROM, NALL, KOSG.  For these stations constraints of
+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).

6. Station coordinates used.

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).

NOTES: UT1 not estimated.  Value given is apriori used in analysis.  The rms is the square of chi**2
per degree of freedom in our solution.  It nominally should be 1.0.  st and sv are numbers of stations
and satellites in solution.

Notes:
 1.  RMS is in cm
 2.  MJD 48809.5 through 48810.5 excluded PRN12 based on the RMS which exceeded 2.3 cm.
 3.  MJD 48807.5 is a revised submission, based on elimination of PRN12
 4.  MJD 48813.5 excluded PRN12
 5.  MJD 48818.5 excluded PRN25
 6.  MJD 48820.5 and 48821.5 are provisional (revised solutions with late data will be reported)
