ICAO, RTCA Seek New Protections for GNSS Aviation Receivers

GPS pseudolite used in experiment at University of New South Wales Satellite Navigation and Positioning Lab

International aviation officials have asked U.S. experts to consider updating standards for GNSS aviation receivers to improve their ability to withstand interference from repeaters, pseudolites, and jammers.  

Repeaters — generally used to extend navigation signals inside buildings where they would otherwise be blocked — rebroadcast GNSS satellite signals and therefore operate in the same frequency band. Although useful within a building,  care must be taken to confined the repeater’s signal lest it confuse other receivers operating nearby.

FAA Begins Opening Airspace to Unmanned Aircraft as NextGen, ADS-B Draw Fresh Scrutiny

Aviation officials Thursday (September 25, 2014) for the first time approved the use of unmanned aircraft for commercial filming in the United States, opening the door to what is expected to be a slow-building gold rush to the skies.

Six companies received exemptions from the existing rules, which generally ban the commercial use of unmanned aerial systems or UAS. The exemptions were granted to RC Pro Productions Consulting LLC dba Vortex Aerial, Aerial MOB LLC, Astraeus Aeria, HeliVideo Productions LLC, Pictorvision Inc., and Snaproll Media LLC.

In August, a group of scientists at the Scripps Institution of Oceanography reported that the severe drought gripping the western United States in recent years is causing a “uplift” in the western United States.

About the same time, governmental agencies were reporting widespread cases of land subsidence in California’s central San Joaquin Valley caused by overpumping of water from wells there.

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.

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.
