SIO PGGA/GARNER Analysis Center Results (04 Sept, 1992)
Yehuda Bock, Peng Fang and Keith Stark
This week we include the following information:
(1) Note on SA tests
(2) Polar motion results for 20-28 August
Note: Our solutions for 20-21 August indicate that there is
a problem at the Usuda site (Japan), and we have subsequently
ignored data from that site. Any feedback from other
processing centers would be appreciated.
(1) Note on SA tests
Our solutions during AS periods do not include data from
the affected satellites (i.e., PRN's 2,16,17,20,21,23,24,25,26,28).
The consequences at this stage:
(a) Our orbital products do not include improvements to these satellites
during the AS period.
(b) Polar motion values for the AS period have larger uncertainties.
(2) Polar motion results.
The set of coordinates described below is based on the
analysis of the of the first 58 days of the IGS campaign, and
include coordinates of the PGGA sites after the Landers earthquake.
The polar motion table has been updated for the period 20-28 August.
1. Analysis Center: Scripps Institute of Oceanography
2. Solution Identifier: Submission 920904
3. Software used: GAMIT/GLOBK
4. Definition of Terrestrial Reference Frame:
Origin: Nominally ITRF-90
Orientation: Nominally ITRF-90
Reference epoch: 1992.57 (MJD 48829.5)
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 u
(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).
(g) On MJD 48800.5, the California sites are treated as separate
sites before and after the Landers earthquake.

NOTES:
(a) 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).
(b) The PEQ notation in the site name (PINB, DS1B, SIOC and JPLB) denotes
post-Landers earthquake position (applicable after 11:58 UTC June 28, 1992).
(c) These coordinates were estimated from the first 51 days of IGS data.
They have been rotated and translated into the ITRF 1990 frame by use
of the horizontal coordinates at all sites. The rms difference between
the horizontal coordinates of these sites and our previous realization
(second IERS submission) was 5 mm.

NOTES: UT1 not estimated. Value given is apriori used in analysis. The rms is the square root 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.

Position Shift of Usuda Station?
--------------------------------
I would like to confirm Yehuda Bock's message about a problem with the
USUDA station. Our records show that on days 221 and 222 there were no
observations from Usuda available. Starting with day 223 we see a shift
in its position of more than 1 meter. We don't use constraints for Usuda,
therefore this shift did not ruin our solutions.
Sorry that this information was not immediately put to IGSMAIL.
--> A clarification by the responsable operational center would be welcome.
