Webinar Describing New Coordinates for NGS CORS Nework Sites Print E-mail
Written by NGS   
Thursday, 10 February 2011

On Friday, February 25, 2011 at 1300h-1430h EST, NGS will host a webinar focused on describing the forthcoming change in coordinates (position and velocities) for CORS sites from ITRF2000 epoch 1997.0 and NAD 83(CORS96) epoch 2002.0. The new coordinates will be available in NGSTRF08 epoch 2005.0 and NAD 83(CORS96A) epoch 2010.0. The underlying datum for NGSTRF08 is based on ITRF2008, but the positions are calibrated for the impending release of IGS08 (+igs08.atx).

In this webinar, we will describe the:
methodology used to establish the new coordinates
magnitude of the coordinate changes
implications for post-processing applications outside of NGS.e.g. holding CORS with fixed positions and use of absolute (vs. relative) antenna calibrations
time-frame for the distribution of coordinates

The presentation will be short with an extended period for participants to share concerns and ask questions. This will be the first of a regular series of presentations on this transition.
   
The presentation will be given by Giovanni Sella and Jake Griffiths, and is open to everyone.

The meeting will be via GoToMeeting via the following link https://www2.gotomeeting.com/register/122817186

Call in number will be available shortly please check this newsletter http://www.ngs.noaa.gov/CORS/news.shtml
