Information - G1 The impact of technique errors on reference frame accuracy and stability
The advance of the International Terrestrial Reference Frame (ITRF) has reached
such a level of maturity that further improvements will require new insights
into the systematic errors affecting all of the contributing observational
techniques and the local ties that relate them. Random thermal measurement
noise is generally not a significant error source any longer, but continued
improvement in the sensitivity of the observing systems is nonetheless desirable
as a means to better expose non-random effects.
This session seeks contributions to identify the important systematic errors
currently affecting ITRF realizations and to clarify the extent that those
effects contaminate geodetic and geophysical results. Experiences with the
ITRF2005 realization, such as possible explanations for the apparent difference
in VLBI and SLR scales, are particularly relevant. Proposals for future
improvements, new approaches, or novel measurement types are especially sought.
