****************************************************************************** DORIS Electronic Mail Fri Dec 18 10:27:54 WET 1998 Message Number 0060 ****************************************************************************** Author: Pascal Willis Subject: ITRS Time Serie/ Call for Participation Dear colleague, I would like to forward you the following message recently issued by the ITRF group. It is important that several DORIS Analysis groups will effectively answer this call for participation. I would like to point out that these solutions do not have to be performed on an "operational basis" (for example, you may like to send a complete year of weekly solution and then wait for some time to send the continuation of the series). I would also suggest to groups starting some DORIS analysis solution to send some serie to Patrick Sillard ( on a investigation basis) at least to analyse the accuracy of their present results. If you plan to answer this Call for Participation, please send me a copy of your proposal. For additionnal questions please contact Patrick Sillard (sillard@ensg.ign.fr) Best regards Pascal ---------------------------------------------------- Author: boucher@ensg.ign.fr (Claude Boucher) Subject: Call for participation ITRS time series *************************************************** * * * CALL FOR PARTICIPATION TO ITRS TIME * * SERIES PILOTE EXPERIMENT * *************************************************** IERS has decided to perform a pilot experiment for time series of station coordinates/EOP. We therefore ask the interested groups to submit their proposal as : 1. analysis center submitting such a series : these centers should submit data as regularly as possible. 2. combination centers : these centers should compute a time series of ITRS from the submitted data and with the use of the local ties for ITRF computation. NOTE : since IGS weekly SINEX submission are already suitable and already available, no specific response is required for IGS Analysis Centers (point 1). The full description of both the experiment and the recommendations are available at : http://lareg.ensg.ign.fr/ITRSTS/appeldoffre.html For any question, please ask Patrick Sillard (sillard@ensg.ign.fr).
