Finally Funded, GPS Adjacent-Band Compatibility Study Now Delayed by Shutdown

Finally Funded, GPS Adjacent-Band Compatibility Study Now Delayed by Shutdown

Although delayed for a year for lack of funding — and delayed yet again by the government shutdown — research to help set GPS-protecting interference standards appears poised to get underway.

The ABC or Adjacent-Band Compatibility Assessment is part of a broad plan to draft spectrum interference standards covering all GPS civil receivers. The approach would give potential users of frequencies neighboring the GPS band clear limits so they can test and plan accordingly.

Harm Claim Thresholds May Be Coming for GNSS

A group of top frequency experts recommended last week that the Federal Communications Commission (FCC) conduct a pilot test of the concept of “harm claim thresholds” (HCTs), an approach that requires receiver manufacturers to build devices capable of withstanding a predetermined level of interference from users in adjacent frequencies.

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.
