Trimble Launches 4-Constellation OEM GNSS Module

Trimble BD930 GNSS Module

Trimble has introduced its BD930 module as part of its GNSS OEM portfolio.
 
This small module features triple-frequency support for GPS and GLONASS plus dual-frequency support for BeiDou and Galileo constellations. Capable of receiving a wide range of commercially available GNSS signals, the 220-channel BD930 takes advantage of all available signals to provide reliable RTK centimeter-level positioning.

Bring Real-World GNSS Satellite Signals Back to the Lab . . . with More Detail Than Ever

Spirent GSS6425 Record and Playback System

Spirent Communications has unveiled a new system for recording real-world GNSS RF signals and replaying them in the lab.

“Record and Replay” is popular as a more rigorous — and, crucially, repeatable — approach to GPS and GNSS testing than using live signals in real time, where satellite positions and atmospheric conditions are constantly changing.

I Fell In Love With GNSS When . . .

“Two GNSS-related experiences really impressed me as a young professional and that I’ve never forgotten. The first involved adjusting a GPS-supported (GPS aerial control) aerial triangulation. By getting rid of most ground control points we managed to produce new results.

ABI Research: Dedicated GPS/GNSS Devices to Reach $7 Billion in 2018

Despite the continued decline in sales of portable navigation devices (PNDs) and the alternative solutions from smartphones, smart watches and eyewear, the portable GPS-enabled device market is anticipated to continue to hold its own thanks to dedicated heads up display/eyewear, cycling, and health/tracking devices, according to a market research company.

Assessing GNSS Receiver Vulnerability in Controlled But Realistic Conditions

Assessing GNSS Receiver Vulnerability in Controlled But Realistic Conditions

GSS8000

At a time when more and more services rely on GNSS for timing, navigation, or location comes the burgeoning realisation that unencrypted, civilian GNSS is vulnerable to accidental interference or malicious meddling.

That the hoaxing of GPS receivers is a reality and not a distant science-fiction threat has been underlined in a typically 21st century way, by disclosures on social media such as youtube.

Peer-to-Peer Counseling

Peer-to-Peer Counseling

First I thought to title these comments, “Learn from the People,” but readers might have confused me with Chairman Mao. (I spent some time recently around the Yangtze River, although I didn’t take the opportunity to swim in it as the Great Helmsman did.)

In any case, my thoughts turned toward the masses and the mass market as a result of working with the authors of an article in this issue on cooperative authentication. They have extended a chain of innovative proposals drawing on the crowdsourcing concept of data sharing among nearby GNSS users or “peers.”

Location Data Increasingly Used to Stop Fraud and Cyber Crooks

Establishing someone’s immediate whereabouts is emerging as a key element in preventing credit fraud and improving cyber security.

The technique uses location data, derived from GPS and other sources, to estimate the likelihood that the person making a request to enter a building, access a computer network, or use a credit card is actually who they say they are.

Cooperative GNSS Authentication

Equations

During the past two decades, the Global Positioning System, together with other GNSSes, has become an essential element of the global information infrastructure, with myriad applications in almost every facets of modern businesses and lifestyles, including communication, energy distribution, finance and insurance, and transportation. Ever-growing dependence on GNSS creates strong incentives to attack civil GNSS, for either an illegitimate advantage or a terrorism purpose.
