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 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 IOV ProtoFlight Model under Assembly

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.

CERGAL 2010, GNSS Certification Symposium, Issues Call for Papers

The 2010 CERGAL symposium will take place in the Baltic city of Rostock, in northern Germany, next April 28-29.

This year, the Symposium on Certification of GNSS Systems and Services will concentrate on maritime and inland waterways applications and GNSS testing infrastructure.

In addition to those topics, papers are invited on GNSS system aspects and aviation, road, rail and other special applications. Abstracts are due on November 30, 2009.

Timing on the Fly

Sensor fusion is a predominant feature of modern navigation systems. To integrate navigation systems with other sensors, the spatial and temporal relationship of the sensor systems must be defined and calibrated.

GNSS Milestones

Rome wasn’t built in a day, and neither was the Global Positioning System.

Nor will the emerging GNSS system of systems arising from the regional and global infrastructures being put in place or modernized today: GPS, GLONASS, Galileo, Compass (Beidou-2), QZSS, GAGAN, IRNSS, EGNOS, WAAS, MSAS, and undoubtedly other acronyms yet to be born.
