A survey of the existence of GPS interference in Europe « Electronic Environment
"One of the objectives of STRIKE3 is the deployment and operation of an international GNSS interference monitoring network to capture the scale and dynamics of the problem, and to work with international GNSS partners to develop, negotiate, promote and implement standards for threat reporting and receiver testing."

"This article presents measurement results from a survey of the existence of GPS interference and jammers within Europe. The measurement started in the late March 2016 and ended in the beginning of July 2016. Interference detection equipment were deployed ‘as is’ in seven European countries; Sweden, UK, France, Czech Republic, Poland, Slovakia and Finland, see fig. 1. In total eleven different site locations are covered among these countries."

"there is a huge variation in the number of weekly events at each site, with some sites having only a few detections per week whereas others have several hundred ... The most active sites appear to be those next to major roads or in city center locations. These are also the busiest sites in terms of vehicles (which may carry jammers) and other sorts of activity"

", the greatest number of chirp type events (which are likely to be intentional and are associated with vehicle jammers) are seen at site 8 and site 10, with a significant number also seen at site 5. Those three sites are close to busy roads and hence that probably explains the high number of these types of events."

A $225 GPS spoofer can send autonomous vehicles into oncoming traffic * | Ars Technica
Billions of people—and a growing number of autonomous vehicles—rely on mobile navigation services from Google, Uber, and others to provide real-time driving directions. A new proof-of-concept attack demonstrates how hackers could inconspicuously steer a targeted automobile to the wrong destination or, worse, endanger passengers by sending them down the wrong way of a one-way road.

KiwiSDR TDoA Direction Finding Now Freely Available for Public Use - rtl-sdr.com
A few weeks ago we posted about some experimental work going on with Time Difference of Arrival (TDoA) direction finding techniques on KiwiSDR units. The idea is that public KiwiSDRs distributed around the world can be used to pinpoint the physical locations of any 0 - 30 MHz transmitter using the TDoA technique. This feature has recently been activated and can be accessed for free via any KiwiSDR.

The KiwiSDR is a US$299 HF SDR that can monitor the entire 0 - 30 MHz band at once. It is designed to be web-based and shared, meaning that the KiwiSDR owner, or anyone that they've given access, can tune and listen to it via a web browser over the internet. Many public KiwiSDRs can be found and browsed from the list at sdr.hu or by signal strength and location on this website.

One thing that KiwiSDRs have is a GPS input which allows the KiwiSDR to run from an accurate clock, as well as providing positional data. Time Difference of Arrival (TDoA) is a direction finding technique that relies on measuring the difference in time that a signal is received at over multiple receivers spread out over some distance. In order to do this an accurate clock that is synchronized with each receiver is required. GPS provides this and is able to accurately sync KiwiSDR clocks worldwide.

Global Radio Direction Finding in Your Browser | Hackaday
Radio direction finding is one of those things that most Hackaday readers are likely to be familiar with at least on a conceptual level, but probably without much first-hand experience. The RTL-SDR Blog has run a very interesting article wherein they describe how the global network of Internet-connected KiwiSDR radios can be used for worldwide radio direction finding. If you’ve got a target in mind, and the time to fiddle around with the web-based SDR user interface, you now have access to the kind of technology that’s usually reserved for world superpowers. Indeed, the blog post claims this is the first time such capability has been put in the hands of the unwashed masses. Let’s try not to mess this up.
