Global Navigation Satellite Systems Engineering, Policy, and Design
Companies who exhibit at the Institute of Navigation GNSS conference next September will have longer exhibit hall hours to work the floor – but fewer days to do so – at the 2013 event in Nashville, Tennessee.
Based on feedback from exhibitors, ION will eliminate the Friday hours for the industry show and increase the Wednesday and Thursday hours next year.

Members of a key technical advisory group told members of Congress this week that a more creative use of interference limits was preferable to setting receiver standards as the way to expand the use of scarce spectrum.
Although the committee focus was on communication devices in general, the issue of GPS receivers and the recent controversy involving LightSquared’s proposed ground-based wireless broadband service.

This is, as they say in Hollywood, a wrap.
The final issue of our seventh year heads off to the printer. And tomorrow I will point my car north and west, returning as generations of Americans have done over the centuries to the family farm, the “home place,” for Thanksgiving.
Because this is the season for gathering in and counting up. For gratitude at what we have received in the year past, and for those untoward things that we have avoided.

With the election finally over, and the chain of decision makers now largely clear, the spectrum war between LightSquared and the GPS community is heating up again with new fronts opening at the Federal Communications Commission (FCC) and Congress.
The focus of the action are changes to rules governing spectrum and receivers that, if enacted, could enable LightSquared to move forward with its plans for a high-powered, terrestrial broadband network.

NavtechGPS presents a series of GNSS courses at the Doubletree Suites by Hilton in Santa Monica, California from December 3 through December 7, 2012.
The classes will take place two long blocks from the automobile-free Third
Street Promenade and four blocks from the Santa Monica Pier (and, of course, the beach).
Register by November 16 for the special hotel conference rate.

Finding your way indoors will be even easier with a new smartphone app from two Portuguese research institutes that augments GNSS with positioning using ultra-low magnetic field communication (ULF-MC).
Fraunhofer Portugal and the University of Porto’s Faculty of Engineering received the €20,000 Galileo Master’s prize for their innovation in this year’s European Satellite Navigation Competition (ESNC 2012) awards. The ULF-MC application was the overall winner from among 406 completed entries (the most ever) submitted from more than 40 countries.

As the forthcoming “Time and Navigation” opening next March at the Smithsonian National Air and Space Museum reminds us, modern navigation depends profoundly upon time — the more precise, accurate, and stable a navigation system’s timing is, the more precise, accurate, and stable its positioning capability.

Various designs of inertial/GNSS integrated navigation systems exist, with different architectures depending on the quality of sensors, the mission, the dynamics of the vehicle, and the non-linearity of the dynamics model, measurement model, or both.
