Subject:  List of coordinates based on 16 months of PGGA analysis
----------------------------------------------------------------- 

Dear Claude/Zuheir:

Enclosed is a list of coordinates that we have computed with respect
to ITRF91 based on 16 months of PGGA analysis at Scripps from August 1991 to
November 1992. The coordinates will probably change again in the near future since
we will be adding GIG 91, Caltrans, VLBI solutions and other data sets, shortly.
Nevertheless, I wanted to send you our latest coordinates so that you could include
them in your next computation. I look forward to any feedback from you, or anyone
in the community.

First, I should note that there are several antenna problems that you
should be aware of:

(1) According to IGS mail #90, the antenna height at Onsala is 0.995 m.
CSTG Bulletin Vol. 5, No. 1, gives a value of 0.985 m to the bottom of
the Rogue choke ring. Which is correct? We use the value 0.985 m.

(2) According to IGS mail #90, the antenna height at Taiwan is 1.766 m.
We have been using a value of 1.775 which I believe we received from
Miranda. Which is correct?

(3) We are using an incorrect antenna height for Ny Allesund of 1.8879 m,
compared to the correct height of 5.203 m. Therefore, you must add the
difference to our listed coordinates. This error has been propagated since
we didn't receive the correct information until after many months of
processing.

(4) We are using an incorrect height for McMurdo of 0.0000 m, since we did
not receive the correct information for many months. The correct height is
4.990 m. Therefore, you must add the difference to our listed coordinates.

(5) According to IGS mail #90, the antenna height at Penticton is 0.118m.
Acording to Herb Draggert this is the old height. The height since day 145,
1991 is 0.115m which is the value that we use.

(6) The antenna height for Vandenberg in IGS mail #90 is 0.903 m. This is
incorrect. The correct height to the bottom of pre-amp base (RINEX standard)
is 1.8416 m.

(7) For completeness, we are using an antenna height of 0.0932 m for Santiago
based on information from Steve Dinardo. IGS mail #90 gives 0.094 m.

Ok, with those antenna discrepancies in mind here are our coordinates:

Notes:

(1) The fundamental sites are the ones used to transform from ITRF90 (AM02)
to ITRF91 (NUVEL-1 No net rotation).

(2) Canberra has three antenna locations.

(3) Usuda has three antenna locations.

(4) Post Landers earthquake values are given for Pasadena, Goldstone,
 Pinyon Flats, Vandenberg and Scripps 2.

(5) Station velocities were obtained by constraining to ITRF91 values given 
 in IGS mail #90.

(6) The epoch for the coordinates is 1992.8360

(7) Enlosed at the end is a file that contains the history of occupation at
the IGS and PGGA sites. I would appreciate any feedback from the community
on this information.
