Global Navigation Satellite Systems Engineering, Policy, and Design
Topcon Positioning Group has released two unmanned aerial systems (UAS) for mapping — the Sirius Pro and Sirius Basic. Both systems are designed to produce accurate solutions for the automated mapping of a wide range of sites — regardless of terrain — including construction sites, mines and quarries, and for use in land surveying, power line and pipeline inspection as well as precision agriculture field mapping.

The high-precision GNSS industry should expect to see industry consolidation and a scramble for new markets and innovations as prices for high-end chips and modules continue to slide, experts told attendees at a ION GNSS+ panel discussion in Tampa, Florida, last week (September 11, 2014).
The falling prices could strain R&D budgets, they noted, but could also create opportunity as high-end receivers come within reach of emerging industries like self-driving cars, unmanned aerial vehicles, and are even incorporated into consumer products.

In 2005, Alison Brown was the first Sidney Sussex College woman alumna to be named as an honorary Fellow in recognition of her distinguished technical contributions. Pictured here with Keith Glover, now head of engineering at Cambridge University, who taught Brown control systems engineering, and Donald Green, her director of studies while she was an undergraduate.SIDEBAR: Alison Brown’s Compass Points
On display in the Smithsonian’s “Time and Navigation” exhibit in Washington D.C. is the world’s first GPS-enabled cell phone. It was developed in 1995 by NAVSYS Corporation, a Colorado GNSS and inertial R& D company, as part of the push to build a national emergency notification system for mobile users, E911.

Scintillation — rapid RF signal frequency and amplitude changes due to signal propagation path changes and phase shifting caused by solar turbulence in the ionosphere — is well known in the GNSS community. However, conclusive scientific studies that cover the whole extent of the question are hard to find. Galileo In-Orbit Validation Experiment (GIOVE) data processing confirmed the effects of scintillation on GNSS receivers, as described in the paper by J. Giraud listed in the Additional Resources section near the end of this article.

Harold “Stormy” MartinHarold W. "Stormy" Martin III will be the new director of the National Coordination Office (NCO) for Space-Based Positioning, Navigation, and Timing (PNT), the focal point for federal agencies working out GPS policy issues.
Martin was the deputy director of the NCO and an Air Force colonel until this summer when he retired from the military. He will succeed Jan Brecht-Clark, who retired at the end of 2013. His start date as director has not been set.

Two European proposals to allow pseudolites in the protected frequencies used by GPS and Galileo could soon be adopted, creating a potential interference risk to GNSS receivers and hampering efforts to protect satellite navigation spectrum, experts say.
