Spoofing will attain virus status, warns expert

November 29, 2016By

As manufacturers convert machines and appliances into remotely controllable objects (the Internet of Things), the potential for spoofing expands, perhaps exponentially. Hackers could interfere with the data supplied to autonomous cars or tracks, remotely forcing them to crash. Although the dangers of GPS spoofing have been pointedly discussed in may technical papers and articles in GPS World since the early... read more

Poll: Experiences with jamming, spoofing and RF interference

Not with Purple Haze, but with signal interference — although, come to think of it, the two may be not unalike, phenomenologically. The October reader’s poll asked “Have you directly experienced any of the following? Check all that apply. GPS/GNSS jamming. GPS/GNSS spoofing. Unintentional RF interference. RF interference from unknown source; unknown whether intentional or not. None of the above.... read more

Expert Opinions: Testing and simulating against GNSS jamming, spoofing

November 8, 2016By
satellites-500x150

Q: What special considerations should be taken into account for testing and simulating against GNSS jamming and spoofing?   A: Current integrations of GPS include a controlled reception pattern antenna (CRPA). Testing with a standard interference or jamming source will not provide accurate results. Wavefront generator simulators are capable of outputting signals that correctly stimulate the GPS receiver’s antenna electronics.... read more

Make it real: Developing a test framework for PNT systems and devices

OPENING GRAPHIC

Tests of the robustness of commercial GNSS devices against threats show that different receivers behave differently in the presence of the same threat vectors. A risk-assessment framework for PNT systems can gauge real-world threat vectors, then the most appropriate and cost-effective mitigation can be selected. Vulnerabilities of GNSS positioning, navigation and timing are a consequence of the signals’ very low... read more

Innovation: Better GNSS navigation and spoofing detection with chip-scale atomic clocks

Getting there more safely
We discuss how chip-scale atomic clocks can help us navigate more safely by allowing a GNSS receiver to position itself more accurately even with only three satellites in view, and to protect itself by being able to detect a sophisticated spoofing attempt. read more

Are you experienced? Tell us about jamming, spoofing, RF interference encounters

October 11, 2016By

We talk a lot about — and publish a lot of technical articles about — GPS/GNSS jamming, spoofing and unintentional RF interference in GPS World magazine and on this website. Clearly it is an emerging and potentially huge problem. How much of it goes on right now?  Tell us very briefly (10 seconds it will take) if You are experienced... read more

Vulcano weapon system to fire with Rockwell Collins NavFire GPS

August 8, 2016By

Rockwell Collins is bringing its NavFire Precision Positioning Service (PPS) GPS to Leonardo-Finmeccanica’s Vulcano family for naval and artillery applications. Derived from the field-proven 12-channel NavFire Precise Positioning Service GPS receiver, Rockwell Collins’ NavStrike military GPS offers high performance GPS for tightly coupled GPS/inertial navigation system (GPS/INS) integrations. “We have customized the NavFire receivers for the particular caliber of the ammunition, and... read more
