Sensonor has announced new features for its STIM300, a small, lightweight micro-electro-mechanical system (MEMS) inertial measurement unit (IMU) that provides non-GPS–aided positioning in multiple domains.

The STIM300 — which can be used underwater, on land and sea, and in aeronautic and astronautic applications — now has real-time g-compensation in al axes and supports rates of up to 2000 degrees/second.

NovAtel Expands Pinwheel Antenna Product Line

NovAtel Expands Pinwheel Antenna Product Line

NovAtel GPS-702-GG-HV

NovAtel Inc. has introduced the GPS-702-GG-HV to its line of high-performance Pinwheel antennas. Tracking L1/L2 GPS and L1/L2 GLONASS frequencies, customers can use the same antenna for GPS-only or dual-constellation applications, reducing equipment costs and need for future redesign. With the same form factor and choke ring performance as the company’s other Pinwheel antennas, the GPS-702-GG-HV has been enhanced to provide the robustness needed for use under high vibration conditions.

Falling Prices Will Spur Innovation, Competition in High-Precision GNSS Market

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.

Alison Brown: Tally Ho! The Hunt for GNSS Innovations

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 Martin Returns to PNT NCO as Director

Harold “Stormy” Martin

Harold 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.
