Sender: owner-igsmail Precedence: bulk ****************************************************************************** IGS Electronic Mail 02 Feb 07:55:31 PST 2007 Message Number 5549 ****************************************************************************** Author: Yang Gao Dear colleagues, The IUGG XXIV General Assembly will be held in Perugia, Italy, July 2-13, 2007 (check the website for details http://www.iugg2007perugia.it/). I like to draw your attention to the following technical session (within IAG GS004: Positioning and Applications): PPP vs DGNSS: Competition or Complementary? While differential GNSS (DGNSS) has become a widely used positioning technology, Precise Point Positioning (PPP) is on its way gaining increased interests within the GNSS community in recent years. With continuous improvements in accuracy/availability of precise orbit and clock products and the development of new error mitigation and data processing methodologies, PPP is going to become an efficient alternative to current DGNSS to many applications. Either seen as a competition or complementary, we need to investigate their roles in the development of next generation real-time kinematic (RTK) systems. This session is seeking contributions to identify and address important issues on the subject from methodology development to case applications, and discuss the potential and challenge in both PPP and DGNSS. Please consider submitting a paper to the session. The deadline for abstract submission is: February 28, 2007 Regards, Yang ********************************************************************************************* Dr. Yang Gao, P.Eng.
