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: 1992.352 (MJD 48750) 
     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, JPL1, SIO1, FAIR, KOKR, USUD, DS10, DS40, DS41, 
DS60, YAR1, MCMU, TAIW, ONSA, WTZ1, TROM and KOSG.  For these stations 
constraint of +- 0.005 m for horizontal components, and +- 1 m for 
height.
   (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.
 (b) These coordinates were estimated from 152 GPS experiments spanning 
the interval from January 1991 to May 1992.  There were 3,398,512 double 
difference observations in the solution.  All site positions were 
estimated and the velocities were constrained to NUVEL-1 North American 
fixed (NAFD) velocities.  To align this solution with ITRF-90, we 
propagated the ITRF-90 site coordinates from their 1988.0 reference 
epoch to the epoch of the coordinates in our solution (1992.352) using 
NUVEL-1 velocities (NAFD).  A six parameter transformation was then made 
between these coordinates and ITRF-90 after applying (most) of the ties 
in IERS TN-10 using only the horizontal coordinates of 11 sites with 
good ties and located outside of plate boundary zones (ALGO, YELL, DRAO, 
FAIR, KOKR, DS40, TAS1, TROM, WTZ1, WETB, ONSA).  The RMS difference of 
the fit after the 6 parameter transformation was 20 mm.  The rotated and 
translated coordinates were then transformed to a AM0-2 frame by 
applying the AM0-2 velocity of the North American plate maintaining the 
orientation the systems at 1988.0
