Trimble Dimensions China User Conference 2009

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.

GNSS Hotspots | November 2009

1. NOTHING BEATS FREE
Mountain View, California
√ Google’s open-source, customizable Android OS uses its own maps for a free GPS feature on the new Verizon Motorola “Droid” phone. It’s shaking mobile map giants Navteq and Tele Atlas and the smart phone and PND developers who lease from them. Google’s free GPS could appear on the iPhone as well.

U.S. Air Force Plans to Improve GPS Constellation Geometry for Military Forces in Afghanistan

U.S. Air Force officials are moving to reconfigure the GPS constellation to create a 27-satellite geometry that will improve the availability and accuracy of positioning, navigation, and timing (PNT) capabilities for U.S. military forces in Afghanistan and Iraq.

Although the constellation currently has 30 operational space vehicles (SVs), not including the SVN49/PRN1 that has still not been set healthy, a number of the spacecraft are located nearby other satellites — effectively creating a 24-SV geometry. (See accompanying figure.)

Galileo Program Recalibrates Schedule, Budget, Open Signal ICD

Galileo program managers appear to have bowed to the unavoidable and acknowledged that completing the European satellite navigation system will take longer and cost more than their revised estimates of 2014 and €3.4-billion ($5.04-billion), respectively

And, although a revised Galileo Open Service Signal-in-Space Interface Control Document (OS-SIS-ICD) will appear soon allowing manufacture and sale of Galileo equipment without a license, the ICD will still require a license for commercial use of the intellectual property contained in the document.

Why is it so difficult to launch a spaceborne GNSS receiver?

Q: Ever wonder why it is SO difficult to launch your spaceborne GNSS receiver?

A: I often wonder if most people, both inside and outside the aerospace community, really understand all the challenges that must be overcome prior to launching a spaceborne GNSS receiver.
