Accurate ties between colocated measurement techniques are essential for the development of the reference system and subsequently accurate measurements of the dynamics of the Earth. Each technique (SLR, LLR, VLBI, GPS, DORIS, gravimeters, etc) brings its own particular strength to the solution, but much of this strength can be lost if we compromise the accuracy over the last few connecting meters. All SLR stations now have GPS receivers, so all stations have at least two measurement techniques. Some stations have more. Please come prepared to discuss the status of your station survey and intertechnique ties: When were they last done? By whom? How was it documented? Anything special about the technique? What kind of monumentation do you use? How good do you think your survey is? How do you know? What are your future survey plans? Do you routinely monitor your system calibration for consistency? This session will include some introductory talks on site stability, but we plan to include sufficient time for discussion. We plan to ask every station to participate. Bring some charts - the projector will be available. See you in Eastbourne, Mike Dr. Michael R. Pearlman Harvard-Smithsonian Center for Astrophysics 60 Garden St. Cambridge MA 02138 tel.
