NovAtel GPS-702-GG-HVNovAtel 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.

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.

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.

The 4th International School on Satellite Navigation is underway in the GLONASS Learning Centre in Moscow, Russia. The school runs through September 24
The event is organized by Roscosmos and JSC Russian Space Systems.
Lectures and hands-on studies cover the history, current status and future of the GNSSes, particularly the use of GLONASS in the Russian economy. It includes two series of lectures and practical exercises of 36 hours each. The first covers satellite navigation and the second the combined use of Earth Remote Sensing and GNSS data.

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.

Seventeen companies have now applied to the Federal Aviation Administration (FAA) for permission to use unmanned aerial vehicles (UAVs) for services that range from filmmaking and photography to oil flare stack monitoring, package delivery and real estate marketing.
A reported White House plan to rely on voluntary adoption of privacy best practices for unmanned aircraft operations appears unlikely to address concerns that the aerial vehicles will be used to spy on people in their homes or abused by law enforcement officials conducting surveillance.
