The 24th international congress of the International Federation of Surveyors will take place at the Sydney Convention and Exhibition Centre in Sydney, Australia.
The FIG 2010 keynote speech will be given Monday morning, April 12 by Tim Flannery,
2007 Australian of the Year. He will speak
about climate change, drawing on his book, The Weather Makers: How Man Is Changing
the Climate and What It Means for Life on Earth, which debuted on
The New York Times bestseller list.
A frequently asked question about GPS is: How accurate is a GPS-based position? The experienced GPS user knows that a big difference lies between using pseudoranges alone or combining pseudoranges and carrier phases.
The following analysis is partly based on an idea raised in the book, Global Positioning System: Signals, Measurements, and Performance, by P. Misra and Per Enge (See Additional Resources section at the end of this article).

Trimble will hold its first user conference in China on December 15-17 at the Jiuhua Resort and Conference Center in Beijing. It will cover civilian technology only.
The theme "Exploration Has No Boundaries," draws comparisons between 15th century navigator Zhenghe, the 2008 space mission Shenqui, and the use of positioning technology to steer exploration.
Trimble head Steve Bergland will deliver one of the conference keynotes.
