Dear colleagues, On behalf of Markus Rothacher I like to invite you for a meeting of IERS WG 3 on Combination on Wednesday, April 27, 2005 18:00 - 20:00 h, The location of the meeting will be the Technical University of Vienna, Gusshausstr. 27 3rd floor. A detailed agenda will be distributed later but you are kindly asked to submit the subject and the expected time for discussion in case that you have some special business. If you check the meeting calender of the EGU you will find announced on Tuesday, April 26 room SM 5 a meeting of the WG 3. But this announcement is misleading because on that date the IERS WG 2 on Site Survey and Co-location will have its meeting. Sorry for the confusion and any inconvenience. With kind regards Bernd Richter
