Feb. 25 NGS Webinar on CORS Network Sites - Open to MALSCE Members

Type:  Featured News  

NGS Open Webinar about the Change in the CORS Coordinates
Friday, February 25, 1 PM

Details below.


MALSCE received the following message from Dave Doyle, NGS Chief Geodetic Surveyor, about an open NGS webinar being held at 1 PM on Friday, Feb. 25.  The change in CORS (Continuously Operating Reference System) network sites coordinates may have a impact on many GPS users in the surveying community.

Webinar Describing New Coordinates for NGS CORS Network Sites

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 and login details will be forthcoming.
