Meeting the USA Challenge and More
A story in which two expatriate students from Poland turn a lifetime of
engineering experience into prize-winning technology for GNSS
Their California startup company—Making Virtual Solid—features a technology whose time had already come. First, they imagined the idea of a giant mirror up in the sky. . .
MVS won the top international award in the 2011 European Satellite Navigation Contest, a growing international effort that attracted innovators from 49 countries this year.

United States and Canadian innovators join 21 other countries and regions to see who has the best commercial ideas for satellite PNT technology
Real-Time Single-Frequency PPP on the Road
A single-frequency precise point positioning technique can provide accurate results in static applications. But can it bring the same benefits to kinematic applications, such as identifying which lane a vehicle is in? Based on the results of field trials in the Netherlands, researchers at Delft University of Technology demonstrate the ability to position a vehicle in real-time precisely
enough for lane identification.
Still posing risks for critical U.S. infrastructure and national defense
Only the backing of a billion-dollar hedge fund operating in the plutocracy that America’s political system has become enables LightSquared to dominate this conversation.
Positioning Using Signals-of-Opportunity Based on OFDM Modulation
E911 and many other location-based services and applications currently require accurate urban and indoor positioning — challenging environments for GNSS. This article suggests that signals-of-opportunity based on the orthogonal frequency division multiplexing modulation offer a way to enhance positioning in these locales. The authors used digital video broadcast-terrestrial signals to develop and test a pseudorange estimation method employing real signals, with results that confirm the theory.
What effect does network size have on network real-time kinematic positioning?

Russian GNSS constellation has 23 operational satellites
The Russian GNSS seems to be enjoying favored status, with official
pledges to match GPS accuracy by 2015, bigger budget requests, plans for
a 30-satellite constellation and a promotional boost as iPhone adds
GLONASS capability to its new release.
First two IOV satellites are in their final orbit and undergoing testing and activation of their navigation payloads
Once expected to reach full operational capability by 2010, the European
GNSS has endured delays caused by technical, political and budgetary
obstacles. If all goes well, initial operational capability will be in
place by 2014.
This cycle is a first-time test for GPS-based technology installed since the last solar maximum.
Space weather—lots of people are talking about it, but can we do anything about it? The current solar cycle will peak in May 2013. What will that mean for GNSS equipment designers and users?
