G52A:
Reference Frames: Determination, Usage, and Application II

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 15649

Session Description:
The quantification of many geophysical phenomena, e.g. sea level variation, co- and post-seismic deformation, glacial isostatic adjustment, loading effects, but also precise orbit determination of artificial satellites, rely on the availability of a global terrestrial reference frame, such as the ITRF. The session solicits contributions from scientists determining or using global reference frames for their applications, focusing on error budgets and other limiting factors. Contributions from analysts of space geodetic techniques (VLBI, SLR, GNSS, DORIS) and their combination are also welcome. Papers on the evaluation and exploitation of ITRF2014 published this year are specifically encouraged.
