Starlink likely uses its own satellites to give a reasonable position. Google luck trying to spoof that.

very easy to spoof, very safe also

@@soothingsounds7491 how do you know?

Sometimes two antennas are not enough in real conditions due to the effects of multipath and fading. In our advanced detector, we use 3 antennas.

Hey may I know how you did the analysis? Thank you

@@shanthoshkumarm6873 Hey, We can’t fully disclose the details of our algorithms, but I can share that we use a u-blox receiver and analyze several key parameters, including: CN0 Pseudoranges Residuals Doppler Gain Spectrum info Datastream I hope this helps! Thank you.

This device operates from a fixed position with user-defined reference coordinates. To detect jamming in motion and determine its boundaries, an additional coordinate source is required, such as an inertial navigation system.

Contact us and we can help you avoid this in the future gpspatron.com/contacts/

im not sure this will help your problem (I'm not as smart as this person) but after changing the geolocation on the iPhone you must reset the phone so it can be spoofed again. Basically after spoofing the phone, you must reset it because any further signals received after you stopped the spoofing will not be read until the Iphone is reset (reset as in hard power off)

This is just a demonstration that GNSS spoofing has become very affordable and easy. Attackers will always find a purpose if critical infrastructure is not protected

In Australia the 7-11 fuel company allows you to lock in a fuel price based on your location for 7 days (so you can travel and still have the cheap fuel) so there is one use - though you would need to use it a lot to pay for the hardware!

A very good and valid question. Indeed, to detect very brute asynchronous spoofing it is not necessary to use any sophisticated detection systems. It is enough just to monitor basic metrics. The problems start when detecting: low power asynchronous spoofing, low power coherent fake signal, quasi-coherent spoofing. Basic detection looks very easy. But to cover all possible scenarios we have already spent more than 3 years and continue to improve our algorithms so the system can work not only in ideal laboratory conditions but also in real city environments with complicated reception conditions, multipath, and industrial interference.

@@GPSPATRON i see, training a NN is probably easier than coding an expert system these days anyway, i was just curious. Also the response time was unreal wow

The software is available only to companies and only after export control procedures have been completed

OK, I get it. We'll talk about that soon

та ладна, а кирилица в ПК автора не смущвет?

Yes, sure.

@@maximbarodzka2670 We want to generate a spoofer so that we detect the spoofing and then we had to implement some mitigation technique,

@@rizwandhanyal1961 That's what this software is designed for.

@@maximbarodzka2670 I have send a quotation request from your official website please respond to that

Hi Davide. First of all, the device is designed to analyze GNSS interference. If we take into account that one of the reasons for the lack of a stable RTK solution may be interference in the GNSS band, the instrument can help here. But if your problem is related to complicated conditions of the GNSS signals reception (closed sky, multipath), then it will not help. We have a cloud service GP-Cloud in which you can stream your data in RTCM@NTRIP format and analyze the quality of GNSS signals reception. Maybe it can help.

@@GPSPATRON Thank you for your reply .well my situation is a bit complicated . In my company we use multiple uavs and each has its own RTK GPS , capable of achieving RTK+ accuracy . An RTK base is also used to send any rtk corrections. Since they are flying UAVs they need to be as stable as possible in flight and thus maintain RTK+. The instrument we are looking for is a high quality instrument that can tell us (in a location survey phase) if that location has interference due to radio signals, obstacles or any other problem , which does not allow the GPS of the UAVs to reach a constant RTK+. To answer your question , we are not looking for overly complicated problems , but simply figuring out whether a given area is suitable for GPS flight ( with an accuracy of centimeters) , through an analysis. One of our perquisites is that there be as large a portion of the sky as possible and away from obstacles that create multipath, but very often there are radio or LTE antennas that jam GNSS frequencies.

@@davidl5786 Thank you for providing more information about your situation. I suggest the following configuration: 1. Redirect the RTCM data stream from your RTK base station to GP-Cloud. This will allow you to monitor the performance of the base station used by your drones during operations. If you're using Septentrio, that's great, as we support their binary data format. 2. Redirect the NMEA@NTRIP data stream from your drones to GP-Cloud. This will enable real-time logging and assessment of your drone receivers, allowing you to analyze their performance. 3. Deploy several of our GP-Probe devices in the field to perform a comprehensive evaluation and localization of interference sources. This will help identify potential causes of disruptions in the drone receivers' operation and provide insights into maintaining stable RTK+ accuracy. By implementing this configuration, you will be able to better understand and address any GNSS reception issues that may affect your UAVs' performance. If you have any questions or need assistance setting up this configuration, please don't hesitate to reach out. Best regards, GPSPATRON Support Team

It depends on the settings you used when generating the IQ data file. In the example from the video the duration is 10 minutes, if I'm not mistaken

@@GPSPATRON So I can use a parameter to tell to the software to make a file for some weeks please ? Thanks again

@@MrDenisJoshua It is better to use another application that generates and sends IQ data at the same time. You can find it on github. Be aware that transmitting an RF signal over-the-air in the GNSS bands is prohibited in most countries.

@@GPSPATRON Thanks a lot again... do you have the name of this soft please ? I'll use only on a place underground... I just must tell to the mobile that I'm home :-)

Hi there. There are two options here: 1. develop your own app based on GPS-SDR-SIM with real-time IQ streaming capabilities. 2. Use any commercial app.

@@GPSPATRON can you please provide any url for tutorial to develop such app.Sounds complicated! Also,please mention some such commercial apps you mentioned….

Our pricing policy is not public. This is a common approach for B2B startups. If you have a specific project, we can discuss it and calculate the cost of the project. Nevertheless, for some products, we plan to make a public price. P.S. GPSPATRON offers the most cost-effective solution on the market for protection against intentional GNSS spoofing.

@@GPSPATRON thing is "cost-effective" is irrelevant if you dont show the price. are you priceing in the 100's 1000 or 10,000's.

@@fastmover45 Price starts at 5k EUR

@@GPSPATRON many thanks for giveing me an insight. a little too much for me for research.best wishes hope you sell lots in the future.

@@fastmover45 thank you. We can provide great discounts for academic users. Especially for GP-Simulator software.

Our GPS simulator gets synchronization from real GNSS signals. It's needed to conduct a coherent attack scenario.

@@GPSPATRON so technically you are constructing a spoofing signal with respect to code delays, doppler frequency and time of the real signal right?

@@copycarvers Exactly. This enables complicated scenarios. A target receiver instantly switches to our fake signal. And then it's possible to move position or time. Learn more here about different attack scenarios: gpspatron.com/types-of-gnss-spoofing/

@@GPSPATRON this is amazing however I am still wondering how much computational and processing performance is needed for such type of attacks? Basically I am interested in studying intermediate and sophisticated spoofing scenarios in MATLAB.

@@copycarvers why do you think that this is a high load task? It's just needed to pre-generate some IQ data and start streaming at GPS frame beginning

Hi Heinz, We used a common frequency-modulated jammer we bought from an online store. Unfortunately, I can not provide a link, so as not to contribute to the distribution of these things.

Nick, be careful with this kind of activity. It is illegal in most countries. I mean to broadcast such signals

The cellphone is send8ng the GPS signal data file to the hackrf. You could also use a computer (Linux, Mac or windows)

Hi David. What software do you use for GPS signal simulation? What hardware?

It's NI LabVIEW powered and based on NI GNSS toolkit

Spoofer --> receiver distance is not very important. It is critical to choose the distance between the jammer, spoofer, and receiver. The jammer must block the original GLONASS and Beidou signals. At the same time jammer should not suppress fake spoofer signals.

but why we need jammer if the transmit position of our Hackrf is nearest, so should be the strongest? And you may forgot mentioned about TCXO clock for hackrf as well?

@@IdrusAlhamid-jz9jt you need to jam the original signals so the receiver will pick up the spoofed ones - think about it like its not a radio because the signal must be confirmed before they are read (like Bluetooth compared to FM radio) - also if you do not jam the original signals, the Spoof protection on the receiver will pick up on the false signals (like how the GLONASS and Beidou were considered "spoofed" signals after the original jamming)
