Inside GNSS • November/December 2011
A San Francisco Bay Area company — Making Virtual Solid–California (MVSC), which snared a trio of awards in a global GNSS competition for its novel approach to driver assistance, is still in early phases of development.
The origins of the company, however, go back more than 40 years to the Cold War era when its principals, Chris Grabowski and Tom Zamojdo, were studying physics and theoretical mathematics at the University of Warsaw, Poland.
But more about that later — first, the news.

Although a Department of Homeland Security (DHS) report on the risks posed by GPS disruptions has yet to be released, the analysis has inspired a proposal to create receivers capable of self-diagnosing spoofing attempts.
“The receiver is the first line of defense,” Logan Scott, president of LS Consulting, told members of the National Space-based Positioning, Navigation, and Timing (PNT) Advisory Board this week.

New Builds • November 9, 2011
Tokyo, Japan–based IP Solutions has released its ReGen GNSS DIF Signal Simulator, a software simulator that simulates ionospheric effects, generates digital IF (DIF) signals similar to those recorded by an RF recorder, and comes with an optional capability of simulating integrated inertial navigation.
Various configurations can produce multichannel GPS and GLONASS L1 signals and single-channel GPS L1, L2, L5 and GLONASS L1 and L2 signals, as well as simulating noise and interference.

[Update November 9 2011] In an ex parte filing with the Federal Communications Commission (FCC) on November 8, a leading GPS advocacy group has asked that the agency “promptly rule” that LightSquared not be permitted to pursue high-powered terrestrial operations in the upper Mobile Satellite Services (MSS) band adjacent to the GPS L1 band.
