****************************************************************************** IGS Electronic Mail 19 Oct 14:49:23 PDT 2006 Message Number 5448 ****************************************************************************** Author: Angelyn Moore Dear Colleagues, The site OBET has been decommissioned. Data has not been available from it for some time. Our colleagues at DLR inform me that following some construction, a new site will be available on a mount nearby. The plan is for this to have a new S-type IERS DOMES number and hence zero horizontal eccentricities. A survey to OBET's marker (14208M004) is planned and will be recorded for a local tie. Current target for the new site is first quarter of 2007. Best regards, Angie ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Angelyn W.

The main goal of the workshop will be the improvement of the IERS Global Geophysical Fluid Centre (GGFC) products in accuracy, consistency, stability, timeliness, user-friendly access, and documentation, to contribute significantly to the "Global Geodetic Observation System" (GGOS) and the users need. The workshop will be held at Hotel Grand Hyatt, Union Square, San Francisco, California, USA, December 6- 7, 2006. The original concept of a Global Geophysical Fluid Centre within the IERS, in which Special Bureaus - defined by the fluids themselves - was an excellent first step to serving the needs of the geodetic community. Ten years on, the community and their needs have changed as the precision of the geodetic observations has been significantly reduced. The division of the GGFC along the lines of the fluid generating the geodetic effect may no longer be sufficient. For example, given the current GGFC set up, a user interested in precise position determinations has to move between the various GGFC Special Bureaus to obtain earth tide models (SBC/SBM/SBT), ocean-load tide models (SBT), atmospheric load-tide models (IERS Conventions), surface mass loading models (viscoelastic and elastic) (SBL) etc. The GGFC would better serve the community such that the user described above only needed to go to a single entry point to obtain all relevant information. Therefore the time is right, to consider a restructuring of the GGFC. At this workshop we will take an insightful review of where we are and discuss options for potential changes to the structure of the GGFC such that today's users can easily find the models and data sets that they need.

Many of you throughout the IGS have had the privilege, as I have had, of working with Miranda over the past years. So you already know what a pleasure it has been to work with her. Miranda is one of those rare people who combines competence and determination with charm and grace. With skills exceeding the merely technical, she shares her enthusiasm and by example, brings out the best in people. Of particular interest to the IGS community, Miranda began the GPS part of her career working on NGS' GPS processing software, OMNI, and translating manufacturer's binary formats into ASCII. She single-handedly worked with colleagues around the world to put together and operate the Cooperative International GPS Network (CIGNET), which preceded the formation of the IGS. When it was time to transition the IGS from a resolution on a piece of paper into reality, Miranda was one of the key people with the experience and leadership needed to make that happen. She continued to help establish GPS tracking stations around the world and in particular the CORS network in the U.S., generously giving her time to train others to her high standards. Miranda can be justifiably proud of her legacy and the respect from friends and colleagues in dozens of different countries. We will miss her deeply and wish her all the best. ----------------------------------------------------------- Dr. Gerald L.

Ferland Dear colleagues, Following several feedbacks received the last couple of weeks, I am proposing minor last minute "fine tuning" to the IGS realization of ITRF2005. 4 stations are affected: Addition: ========= CORD: This station was in earlier proposed realizations. It had been removed because the station was decommissioned. The station will be recommissioned and the same equipment will be reinstalled! (D. Stowers). This is conditional to the coordinates time series resumes without discontinuity. LHAZ To replace LHAS (a few meters away) suggested by R. Stoeger. At the site all ACs have been using one or the other. 2 ACs have been using LHAZ regularly. Deletion: ========= GOUG Data problems. Likely difficult to improve in the short term due to the remoteness of the station. FAIR Due to the gradual degradation of the residuals (mainly in the North/South component). The cause is likely related to non-linear motion due to post-seismic effects caused by the Delani earthquake. Those deletions are very unfortunate as the two stations have some very desirable characteristics. Other Stations: =============== The coordinates & velocity changes of the other stations between the current and updated proposed realization are unchanged (<< 0.1mm & << 0.1mm/y). This applies to both versions of the realization IGS05 & IGT05. The total number of stations in remains 132. The update can be found at the usual location: ftp macs.geod.nrcan.gc.ca cd /pub/requests/sinex/IGS05 Transformations: ================ For those of you who may want the transformation from IGS05 (with absolute antenna phase center) and IGb00 (relative antenna phase center) they are (at epoch 2000.0): R X (mas) : -0.0070 R Y (mas) : 0.0340 R Z (mas) : -0.0069 T X (m) : -0.0003 T Y (m) : -0.0015 T Z (m) : -0.0061 SCL (ppb) : 0.7125 d R X (mas/y) : 0.0033 d R Y (mas/y) : -0.0001 d R Z (mas/y) : -0.0161 d T X (m/y) : -0.0004 d T Y (m/y) : 0.0007 d T Z (m/y) : -0.0018 d SCL (ppb/y) : 0.1748 Note that the transformation of the IGS realization, using relative phase center only, they have been provided in the earlier e-mail (Sect. 4-1): http://igscb.jpl.nasa.gov/mail/igsmail/2006/msg00170.html A comparison of the two sets of transformations indicates that the phase center change causes variations in the transformations: Rotations < 0.02mas, Translation < 1mm, Scale < 0.2ppb The effect on the rates is negligible. Starting with GPS week 1400, the "parallel" solutions using the absolute phase center provided by the ACs will become the official solutions. This imply that there won't be any combination for those parallel solutions posted at the usual ftp. The cooperation of all those that have been contributing to this long transition phase is very much appreciated! Thanks also to all of those that have been providing feedback on the various versions of the proposed realization!
